Ace tactical shooter and gunsmith Jim See of Elite Accuracy LLC recently tested a Frankford Arsenal rotary brass tumbler. Like the older Thumbler’s Tumblers, this can tumble your cases in a liquid solution. The wet-tumbling process worked very well Jim reports. Posting on Facebook, Jim noted: “I was super impressed with the Frankford Arsenal rotary tumbler and cleaning packs they sent me. I ran 350 pieces of brass for one hour. They now look great.” Jim appreciated not having to deal with dry tumbling media, such as crushed walnut shells. Dry media produces dust and can leave residues or clog flash-holes.
Interestingly, Jim recommends you try wet-tumbling WITHOUT using stainless media. At least give it a try. Tumbling without media simplifies the process and you don’t have to worry about pins stuck in flash-holes or case-necks*. Jim reports: “Stainless steel pins come with the Frankford kit, but mine hit the trash right out of the box. There is no need to clean the inside of your cases 100% and that’s all the pins add to the equation. The brass bumping brass with hot water and Frankford’s liquid cleaner works great all by itself.” One wag stated: “That’s great to hear. Stainless steel pins are a PITA.”
Other Facebook posters concurred with Jim’s evaluation of the Frankford Arsenal Rotary Tumbler:
“I’ve had one for a couple years, and it works well. I usually run about 250-300 Dasher cases at once in it. But I use the pins because I’m OCD about clean brass.” — David W.
“I’ve had one for a year and a half and it definitely works with or without pins.” — Luke C.
“I got one about six months ago and have yet to use any SS media. I just use some dawn, distilled water, and Lemi Shine®. Turns nasty 5.56 range brass bright and shiny.” — Brian D.
“I don’t use the pins either and use a combination of Dawn soap and Lemi Shine.” — Jon N.G.
This video shows how to assemble and operate the Frankford rotary tumbler. NOTE That Jim See does NOT feel that it is necessary to use stainless media.
How to Dry Your Brass — Hair Dryer Vs. Machine
The downside of wet tumbling is that you end up with a pile of wet brass at the end of the cleaning cycle. There are many ways to dry brass, from drying in the sun to using a kitchen oven (be careful not to “overcook” your brass). One Facebook poster asked Jim: “What is your drying method for wet brass, and how long does it take?”
Jim See replied: “To start I just drain off the dirty water, and rinse the brass with clean hot water. Then I roll the brass on a towel for 30 seconds and put the brass in a one-gallon bucket. Next I insert a hair dryer in the bucket (with the brass) and let it run for about 5 minutes. With this procedure, the drying process for me is done in less than 10 minutes.”
Jack Lanhart has another method: “I use a food dehydrator. It takes 30 to 45 minutes.”
For those who don’t want to mess with towels and hair dryers, Frankford Arsenal offers a matching Platinum Series Case Dryer that simplifies the process of drying brass. Lyman also makes an excellent Cyclone Case Dryer. Both drying machines cost about $60.00 and both have multiple levels so you can separate different types of cartridge brass. Lyman states that “The forced heated air circulation of the Cyclone will dry your brass inside and out within an hour or two, with no unsightly water spots.” The Lyman dryer can also be used for ultrasonically-cleaned gun parts.
*The Frankford Rotary tumbler does include media separators if you choose to use the provided pins or other media. CLICK HERE for diagram showing how to use media separators.
Factory-loaded ammunition has become very hard to find, particularly pistol ammo. Concerns over social unrest, personal security, and the upcoming election have spiked demand for loaded ammo. Everyone is asking “where has all the ammo gone?”
Pistol Ammo Hard to Find
In particular, 9mm pistol ammo flies off the shelves as soon as it arrives, and even major online vendors such as Midsouth Shooters, MidwayUSA, and Natchez have very limited supplies.
Need Ammo? Load Your Own…
One answer to the ammo shortage is to load your own. And if you want to produce a large quantity of ammo in a short amount of time, the progressive press is the answer. There are many progressive press systems, from modest Lee progressives to high-end, automated systems from Mark 7 (Lyman). In this article we feature the “latest and greatest” progressive press from Dillon — the new eight-station RL 1100 Press with Case-Feeder.
Our friend Gavin Gear of UltimateReloader.com got his hands on Dillon’s impressive new RL 1100. In two videos, Gavin shows how to set up the RL 1100 and then he demonstrates how to produce 9mm pistol ammo with this impressive 8-station press.
Gavin says: “My Dillon RL-1100 is cranking out the 9mm, and in this video we bring it up to ‘full tilt’ speed” [with the MR. Bullet Feeder and the Dillon Case-Feeder]. If you watch the video, you’ll see Gavin produce 9mm ammo at a rate of nearly 50 rounds per MINUTE!
Gavin equipped his new RL 1100 with two cool products from Double Alpha Academy (DAA) — the Mr.Bulletfeeder® as well as an advanced, Magnetic Powder Check. When loading ammo you can never be too safe, so we definitely recommend the use of powder-check dies (we use a conventional RCBS powder-check die on our progressives). The DAA bullet feeding system is an important add-on that significantly increases output rates when used in concert with the Dillon Case-Feeder (blue funnel).
RL 1100 Reloading Stations with Powder Check and Bullet Feeder
RL 1100 Stations shown above:
1. Case inserter
2. Sizer/De-Primer
3. Swager (with hold-down)
4. Priming (no die)
5. Powder charge and expansion (expansion for pistol cartridges only)
6. Double Alpha Magnetic Powder Check
7. Mr. Bullet Feeder bullet feed die
8. Bullet seating and Crimping
Note: In order to accommodate the magnetic powder check die AND the bullet feed die, bullet seating and crimping were combined at the last station.
The RL 1100 has some very impressive features that allow faster and easier ammo production. An Eccentric Roller Bearing Drive System reduces friction. The RL 1100’s heavier frame provides greater rigidity for more efficient cranking. The RL 1100 also boasts an improved shellplate indexing system. Priming is enhanced through a spring-loaded Priming Station Locator and Upgraded Primer Pocket Swager.
Dillon RL-1100 Set-Up Video:
Loading with the “Turbocharged” Dillon RL-1100
Gavin was very impressed with his RL-1100: “This reloading setup is [great]. Every crank of the lever yields a completed cartridge, and the attainable speeds are AMAZING. The case feeder and bullet feeder had no trouble keeping up with my quick pace using this setup. And it is great to know that every powder charge is being checked.
This press is very reliable and smooth, bridging the gap between lower cost home set-ups and six-figure commercial loading equipment packages. What’s next? I’ll be performing a caliber changeover to .308 Winchester.”
The DAA Magnetic Powder Check can be used on a variety of Progressive Presses.
Benchrest and F-Class shooters know that you need a very good rear bag to achieve optimal (and repeatable) accuracy with your rifle. The rear sandbag does more than just support the weight of the rifle in the rear. It also aligns the stock with the front rest, absorbs vibration/shock, and perhaps most importantly, guides the rearward travel of the stock during the recoil cycle.
A premium bag will be stable from shot to shot, not move on recoil, and also be a good match to the angles and width of the keel (bottom) of your stock. Modern rear sandbags also employ various types of synthetics on the contact surfaces. The idea is to reduce friction which still providing a stable “grip” on the stock.
We’ve learned that our friend Sebastian Lambang, inventor of SEB coaxial rests, has come up with an improved, second-generation Bigfoot Rear bag. The design looks very well thought-out and the craftsmanship is excellent. Seb welcomes comments on his Facebook Page. These will be available soon from SEB dealers worldwide.
Seb explains: “Here is the new/premium SEB Bigfoot Rear Bag. The photos show our Prototype bag model shown with nylon seat belt material on the ears.” Note that the bags sit perfectly flat — there is no bulge on the bottom even though the bags are “packed to the brim with sand”.
Dimensions: Standard spacings between ears: 3/8″, 1/2″, 5/8″, 3/4″, and 1″; standard height: 4″.
Customizing: Other spacing, bag height, for right- or left-handed available on request.
Accessories: The SEB doughnut (bag base/surround unit) is also available (sold separately).
Here is gunsmith Richard King, with his updated Martini Mark III smallbore rifle.
This is the kind of family-friendly, “feel-good” story we like. A few years back, Texan Richard King created a rimfire benchrest rifle using a classic Martini Mark III smallbore action. He fitted the gun with a new flat, wide forearm and a new buttstock, allowing the gun to sit steady on the bags and track smoothly. The narrow action was also fitted with a cantilevered top rail to hold a high-magnification scope.
Here is Vicki King, with Martini Mark III and her trophy.
But here’s the best part. Back in 2014, Richard provided this updated classic to his wife Vicki, who proceeded to win a rimfire benchrest match (Vintage class) with the old Martini. Richard reports: “Here is my lovely wife with her High Overall Vintage trophy. That is a Martini Mark III that I re-stocked in walnut for 50-yard, .22-caliber benchrest matches. It’s great to have her shooting with me again.”
Bravo Richard — kudos to you AND to your lovely bride. It’s great to see a couple shooting together. It’s also great to see a classic rifle brought back to the winner’s circle with some inspired stock-work, new optics mount, and other smart upgrades. Old rifles never die… at least if they find their way to a great smith like Richard King.

Forum member Nodak7mm has discovered an ideal way to store your rifle cleaning rods in your garage or loading room. Using inexpensive Berkley Horizontal Fishing Rod Racks, Nodak7mm has secured a half-dozen Dewey rods on the back of a door. You could also mount the racks along a wall or on the side of a storage cabinet. This installation takes up minimal space and the Berkley Racks cost just $11.96 at Amazon (select “6 Rod Rack”) or $16.50 per set at Walmart. If you prefer wood, Amazon also sells a pine 6-rod wall rack for $22.45.
Nodak7mm explains: “I was moving some fishing poles around and ended up with an extra pair of Fishing Rod wall racks. I said to myself, ‘I bet this would hold my Dewey cleaning rods’. I mounted the pair on the inside of a closet door in my man cave and put my cleaning rods in it. It works like a charm and is far cheaper than a specially-made rack that only lets the rods hang. One can even slam the door with the rods mounted and they stay put. This rod rack set… is made by a nationally recognized name and does a great job of holding the cleaning rods securely and safely.” These are inexpensive and are easy to mount to a door or wood cabinet.
Stow Your Cleaning Rods on Your Gun Safe
Another option is to make a rod set with a magnetic backing strip. This can be affixed to the sides of your gun safe or steel storage cabinet. Here is a home-made, magnet-affixed cleaning rod holder made by Forum Member “BobM”. This smart installation works great. CLICK HERE for more information.

Editor’s NOTE: Shelley Davidson passed away in 2008 after a courageous battle with cancer. He was one of the great innovators in benchrest rifle design. This article, written before Shelley died, showcases Shelley’s creative talents at their best. His “Tinker Toy” design will always be a tribute to Shelley’s fabricating skills and imagination.
Shelley Davidson — a brilliant innovator. R.I.P. Shelley — you will not be forgotten.
Shelley Davidson’s peers called his radical rifle the “Tinker Toy” gun. We call it revolutionary. Even now, 14 years after its creation, there’s nothing quite like it. This innovative, skeleton design threw conventional wisdom to the winds. Shelley readily concedes he “broke the rules” of benchrest rifle building. But this was inspired rule-breaking, because Davidson’s rifle shot like a house on fire. The Tinker Toy gun won its first matches, both for Score AND for Group. And this rifle also delivered many “zero groups” in Gene Begg’s Texas Tunnel. Hats off to Shelley for conceiving and building a truly radical rifle that was also wicked accurate and successful in competition.
Tinker Toy 30 BR — Radical As It Gets
Report by Shelley Davidson
Although I’m not big on naming rifles, my shooting buddies have christened the gun “Tinker Toy.” I can live with that as it does kind of look as if it was made with a Tinker Toy set.
Origins of the Project
This project began with some wild ideas I had in the fall of 2006 about using magnets to tune a barrel. My idea was to use one magnet on the barrel and another on the stock so they pushed against each other to counter gravity-induced barrel sag (and possibly) tame barrel vibration in a beneficial manner. The only way to test these ideas was to build the device and mount it on a gun. That meant I had to build a new rifle because there was no place to mount a magnet on the stock of a conventional benchrest rig. I had a Kelbly-stocked heavy varmint stock with a Michael Kavanaugh paint job on it. I didn’t think Kav would ever forgive me if I started drilling holes in one of his works of art. My light varmint was in a carbon fiber Scoville stock that costs about a grand. Drilling into the Scoville for an experiment just smacked of bad judgment. So, the magnet thing was my first motivation for designing a new stock. As long as I was building from scratch I decided to offset the barrel and action 0.75″ to the right to counteract the spin/torque from the bullet.
Although there’s nothing new here, my second motivation was to build a 30BR that could shoot in the 10.5 lb light varmint class in NBRSA. The magnetic tuner will automatically make this gun illegal in the IBS. The IBS has declared all barrel attachments un-safe and have outlawed them. I personally feel that the IBS really outlawed all barrel attachments to prevent experimentation and innovation. But at least we have NBRSA matches.
Designing the New Gun — Thinking “Outside the Box”
Once I’d decided to build a lightweight stock that could support experimental devices out near the muzzle, I started drawing up some rough plans. I also took a trip to Jerry Stiller’s shop in Wylie, Texas for a brainstorming session with Jerry, the maker of Viper and other Benchrest actions. Jerry is a school-trained mechanical engineer and thinks differently than I do. I came away from Stiller’s shop with my design roughed out and sketched on paper. The design violated several covenants of conventional wisdom for building competition BR rifles. For instance, two-piece stocks stress the action. Stress reduction is why most BR rifles are glued into the stock. Another myth is that metal stocks vibrate too much so wood or foam-filled fiberglass or carbon fiber are used.
Tinker Toy Rifle DESIGN FEATURES
Shelly Davidson’s Rifle was so innovative, that almost every feature, except the bare action, is very different than you’ll find on most Benchrest rigs. Accordingly we felt it would be useful to isolate and describe the key design features, from stem to stern. Click thumbnails to view FULL-SIZE PHOTOS.
Front Bracket with Magnetic Tuner
The tuner consists of one rare earth magnet attached to the stock and another attached to a barrel sleeve with the magnets oriented so as to make the magnetic force repel each other. The purpose is to counter “barrel droop” and, hopefully, dampen barrel vibration. The lower magnet is carried on a threaded shaft (with lock ring), allowing the magnet to be raised up and down to adjust the “up push” on the barrel.
Tubular Fore-Arm Supported by Brackets
Three brackets support two tubes, one on either side of the barrel. The rear-most bracket is sandwiched between the barrel and the action. Four inches forward (max distance allowed for barrel blocks) a second bracket grips the barrel. Near the muzzle a third bracket secures the ends of the tubes and holds the magnetic tuner. To allow barrel offset, the left tube is 1″ diameter tube while the right tube is 5/8″ diameter.
Offset Barrel The rifle rests on a 3″ wide plate attached to the underside of the two fore-end tubes. With the plate centered in the front sandbag, the barreled action is actually offset 0.75″ to the right (looking forward from the breech). The purpose of this offset is to keep more weight on the right side to counter the tendency of the rifle to torque counter-clockwise. Two different diameter tubes allow for the built-in offset.
Floating Action without Sub-Support or Bedding
On the Tinker Toy gun, the action serves as a load-bearing assembly, holding the barrel in the front, and the skeleton buttstock (or “keel”) in the rear. Shelley was told that accuracy would suffer if you stressed a benchrest action in this manner but that proved untrue. It is a very simple solution to building a rifle, and it eliminates the need to bed the action. The forearm attaches to the action via a bracket installed like a recoil lug.
Skeleton Rear “Keel” Affixed Directly to Action
Davidson’s Tinker Toy does not have a conventional rear buttstock. Instead there is low-profile, v-shaped metal “keel”, as Davidson calls it, that rides the rear bag. The keel is supported by a tubular backbone that attaches at the rear of the Diamondback action. At the butt end is an aluminum plate covered with bubble wrap that serves as a butt pad. The skeletonized rear section helps the rifle maintain a very low center of gravity.
Locked Scope with External Windage and Elevation Adjustment
Shelley ran an older Leupold 36X Benchrest Scope with front-adjusting objective. To eliminate slop or loose tolerances in the erector mechanism that could cause changes in point of impact, the internals have been locked up by Jackie Schmidt. To move the cross-hairs relative to the bore axis, Shelley has a special Jewell/Foster rear ring that allows a limited amount of lateral and vertical movement of the entire scope body.

Stiller Diamondback Action and Shilen 17-Twist Barrel
I had wanted to use an aluminum Stiller Cobra drop port with a 6mmBR bolt face but Jerry had none in stock and he estimated it would be a year before one was available. Although I’ve waited for up to a year for an action in the past, I wanted to build this rifle during the fall of 2006 while the weather was pleasant enough to work in my unheated and un-air-conditioned garage shop. Jerry did have a 1/2″ short stainless steel Diamondback in stock so I purchased it even though it would add 3 ounces to the gun compared to the aluminum Cobra. Three ounces is a lot of weight when you’re working with a 10.5-lb limit. I had a heavy varmint contour Shilen 17-twist barrel that would work nicely and I had a Jewell trigger on a rifle that I wasn’t using at the time. I also decided to use my Leupold 36X (locked-up by Jackie Schmidt) with the Jewell/Foster adjustable rings.
Building the Tube Fore-Arm and Brackets
I took a wild guess as to tubing thickness and settled on .035″ for the 1″ left fore-arm tube and .058″ for the 5/8″ right fore-arm tube. All of the flat stock and tubes are 6061 Aluminum. I did the lathe work and the mill work and every evening I’d put the parts together and think about the proper way to proceed.
When the parts were mostly made, I started thinking that this was a truly ugly rifle. I thought about painting it but that wasn’t a good option as many of the parts are designed to slide over others and glue together. Anodizing was the best answer so while looking on the Internet for local anodizing shops I Googled “Home Anodizing”. Sure enough there were a few sites that told about how to anodize at home. I picked up some battery acid from NAPA Auto Supply, some Rit Clothes Dye from Wal-Mart, and a bunch of distilled water from the grocery store. Using an old battery charger as my dc power supply I started anodizing and dying the eighteen parts that went into the stock. Although I had to strip and re-anodize some of the parts, the work turned out acceptable.
Putting it All Together–Lug-Mounting the Fore-Arm and Lots of Epoxy
The barrel contour had to be modified to work with the stock which attaches by way of a rear plate which mounts like a recoil lug and a plate that ties the barrel and the stock tubes together 4″ forward of the bolt face. The four-inch maximum distance is a NBRSA rule concerning barrel blocks.
The recoil lug-style stock mount is probably the only truly innovative thing I did other than the opposing-magnet tuner. Basically, the rear bracket is sandwiched between the receiver face and the barrel shoulder–positioned where a conventional recoil lug would go. I also added a brass ring (visible in photo) between the anodized bracket and the barrel. This was done to distribute loads over a wider surface area. (I was concerned that the bracket material was fairly soft and I didn’t want to crush it as I torqued the barrel in place.) After fitting the barrel and plates I glued the entire gun together using epoxy and various LocTite adhesives. The rest of the parts were assembled but I did not Loctite the scope bases since I thought I’d be disassembling the rifle for re-work after the first trials. That came back to bite me during later testing when the gun started shooting erratically and I went down a couple of blind alleys before finding the loose bases.
Range Testing–Results Are Very Positive
The first range session was a real shocker. Even though the wind was up to 10mph and twitchy, the rifle showed promise from the very first shot. I really didn’t expect that kind of performance without, at least, some rework. After sighting in, I shot five, 5-shot groups that, when averaged together, measured .223″. That’s good enough to win some benchrest group matches. But I wasn’t finished with the gun yet–I still wanted to try out my magnetic tuner concept.
The Magnetic Tuner
Next, I built the magnetic tuner. The tuner consists of one rare earth magnet attached to the stock and another attached to a barrel sleeve with the magnets oriented so the magnetic forces repel each other. In order to test the magnets and to determine if the rifle really shot as well as it seemed to, I took it to Gene Beggs’s shooting tunnel in Odessa, Texas. I spent two days at the tunnel testing loads and then installed the magnetic tuner. The gun shoots well with the magnets and shoots well without them. I suppose I can’t make any claims as to how much, if any, improvement the magnets make. Gene said that my gun was the most accurate rifle to be tested at his one-year-old shooting facility: “Shelley Davidson brought one of the most unusual rifles I had ever seen; he called it his ‘Tube Gun.’ And boy, did it ever shoot! It still holds the record in the tunnel as the rifle that shot more zeros than any other to date.” I definitely recommend Gene’s facility for testing and refining shooting techniques and loads.
Competition — Tinker Toy Won Both Score and Group Matches
Finally the big day arrived when I’d shoot the first match with my new gun. The North Texas Shooters Association was holding its first club match of the 2007 season. At the Denton, Texas matches we shoot a Score Match in the morning and a Group Match in the afternoon. The March event was at 100 yards and the April match will be at 200 yards and so on alternating throughout the benchrest season.
Match One–Tinker Toy Wins Score with a 250 – 17X
Since the gun is chambered in 30BR and that chambering is almost immune to tuning woes, I preloaded 130 rounds with H4198 powder and 118gr Cheek bullets. I used my SEB front rest and rear bag which are made by Sebastian Lambang in Indonesia. Everything came together, and Tinker Toy demonstrated that the accuracy it showed in the tunnel was no fluke. The gun shot great and I won the morning match with a 250, 17X. The day was quite windy and the next best shooter scored a 250, 15X. So I’d chalked up my first win.
Match Two–Tinker Toy Wins Group with a .2282″ Agg Tinker Toy won the afternoon group match I entered with a five-group Aggregate of .2282″. (The second place score was .2568″.) My groups were .149″, .197″, .243″, .302″ (oops), and .250″. You know how some folks say a 30BR can’t be competitive with a PPC? Well that .2282″ Agg won’t break any records, but it is good enough to win some regional registered BR matches. So this rifle has demonstrated an ability to win in both Score and Group matches. Obviously I have a very good Shilen barrel, great Cheek bullets and the rest of the components are doing their jobs as well. But, the stock is also working well.
Score Shooting vs. Group Shooting–The Rules
In a score match, the shooter shoots one bullet at each of five record targets, which are clustered on one target sheet. The Aggregate score of five of these targets determines the winner. If the shooter touches the 10 ring on all of his 25 targets he can score a “clean” 250 score. Usually there will be more than one shooter who scores a 250 so the winner is determined by the X-count. The 1/2″ 10-point ring has a 1/16″ dot in its center. Touching the X dot adds to the shooters X count. In short-range group matches, the shooter must try to put five bullets through the same hole. At each distance (100 or 200), five, 5-shot matches are scored, the group sizes are added together (MOA equivalent at 200) and the total is divided by five to arrive at an Aggregate score.
Today is National Hunting and Fishing Day. To help the avid hunters among our readers, here are Twenty Tips that can help ensure a safe and successful hunt. These tips have been compiled from our AccurateShooter Hunting Forum, with help from Hunting Editor Colton Reid (who has already been out hunting this month). Some items are preparatory — such as working with maps, sighting in the rifle, and improving physical fitness. We also talk about equipment — having the right gear, from proper boots to a GPS for multi-day hunts.
Of course there are entire volumes written on hunting, but these 20 Tips can benefit all hunters. Follow these suggestions and you should have a safer hunting experience with greater likelihood of success. If you liked these pointers, you’ll find two dozen more helpful hints on the NSSF Website.
Preparations Before The Hunt
1. Map Your Hunt and Notify Others — Before your hunt, make a plan and notify friends and family members about WHERE you are going and your intended return date and time. Print out a Google Satellite map and locate landmarks and trailheads. Mark where you plan to park your vehicle and give a copy of this map to friend and/or family members. A hunter may injure himself by falling off a rock, or tumbling in a creek-bed. After that kind of injury the hunter may be confused or unable to walk. If you get stranded in the wilderness, you want trusted persons to know where you are. So, before you leave on a trip, provide a map to a friend or family member. Show them where you will leave your vehicle, and where you expect to be every day of your hunting adventure.
2. Licenses and Permits — Make sure you have a valid hunting licenses and all the necessary tags. Begin this process with ample time before your intended hunt(s). The NSSF adds: “If you are crossing state or national borders, find out about any special considerations you must take care of. Border crossings can mean knowing about firearm transport laws or Chronic Wasting Disease-related regulations.”
3. Work on Your Fitness — On a multi-day hunt you may be trekking many miles. You need to be in good shape. If you are out of shape you may be putting yourself in a precarious situation, particularly if you underestimate the terrain difficulty. As the NSSF says: “Not being able to handle the conditions lessens your chances of success, can turn a great experience into an agonizing one and can endanger your health.”
4. Do Your Homework — Study the area you will be hunting. Talk to other hunters. Look at satellite photos. Get a real sense of the walking and terrain challenges. For a multi-day hunt, MAKE a PLAN. The NSSF states: “Eliminate surprises. Learn as much about where you will be staying, the area you will be hunting, what the weather might be like and what you need to bring[.]”
5. Rifle and Ammo — Make sure your rifle is sighted-in and your ammo is tested. Sight-in your rifle with the ammo you plan to use on your hunt. CLICK HERE for 4-Shot Sight-in Method. After sighting-in from the bench, confirm your zero by shooting from typical hunting positions (kneeling and with forearm supported on a rock or post).
6. Shooting Positions — Practice the shooting positions you will use in the field. Practice sitting, kneeling, and prone positions. You should also practice with shooting sticks, using your day pack as a rest, and with a bipod. Try to have a rock-steady rest before taking your shot.
7. Back-Up Irons — If possible, select a rifle with back-up iron sights. While modern scopes are very durable, they can and do fail (glass can crack). If you’ve invested a lot of time and money in your hunt, back-up iron sights can keep you in the game even if your riflescope fails.
8. Communications and GPS — Bring a GPS if you are in a wilderness area far from civilization. It’s a good idea to bring a cell phone, but you may not have coverage if you’re quite a distance from populated areas. A smart-phone also doubles as a digital camera to record your trophies. For navigation and safety, consider getting Garmin inReach Explorer+. This high-tech handheld unit features interactive SOS, connecting you to the GEOS 24/7 search-and-rescue monitoring center. They also allow you to send and receive text messages, no matter where you are, via advanced inReach satellite technology. Yes you can communicate even if you are miles from the nearest cell tower.
9. Select Good Gear — Make sure you have GOOD BOOTS that are comfortable — you’ll spend a lot of time on your feet. You may want a pack with harness for your rifle so you have both hands free. On a multi-day trip, make sure you can carry enough water, and that you will stay warm enough at night. Good practices for backpacking apply to multi-day hunts.
10. Make a Checklist — Create a complete checklist of the gear and supplies you need. That includes arms, ammunition, rangefinder, binoculars, proper clothing (including spare clothes), hunting accessories, sleeping gear (on multi-day hunts), toiletries, medications. Don’t forget a good first aid kit — lots of bad things can happen during any wilderness trip. You can cut a hand, break an ankle or worse.
During The Hunt
11. Have a Plan — know where you plan to go and when. Try to be where you want in the early morning and early evening hours when deer are likely most active.
12. Take Your Time — If you spot a deer and get too excited and don’t take your time you may spook him. Go slow and glass. If possible, wait for the animals to bed down and relax. Then work out the best way to approach your prey. Remember, “You get so few opportunities, don’t screw it up!”
13. Glass More, Walk Less — Let your eyes do the walking — get good binoculars and use them. With their heightened senses of smell and hearing, deer/elk are able to spot you way better than you can spot them. If you are walking around a lot, chances are you are getting spotted by your prey.
14. Riflescopes Are Not Binoculars — Never use a riflescope as a substitute for binoculars. The temptation to do so is real, but when one does this, one is by definition pointing the muzzle of the gun at unknown targets. We like binoculars with built-in rangefinders. When glassing at long range, try supporting your binoculars on your pack.
15. Be Sure of Your Target before Shooting — Every year during whitetail season, farmers everywhere are forced to spray-paint their cattle or risk having them “harvested” by hunters who don’t bother confirming the species in their sights. Hunters with “buck fever” can make mistakes. When in doubt, don’t shoot.
16. Know When to Unload — When finished hunting, unload your firearm before returning to camp. You should also unload your gun before attempting to climb a steep bank or travel across slippery ground.
17. Hearing Protection — While pursuing and stalking your prey you’ll want full sensory use of your ears. But when you’re finally ready to take the shot, slip in hearing protection. A shot from a large-caliber hunting rifle can exceed 170 decibels. Unprotected exposure to noise from a SINGLE 170+ dB shot can cause permanent hearing damage. (Source: ASHA.org). If you make a follow-up shot, you double that noise hazard. Therefore a hunter with a non-suppressed rifle should have hearing protection available.
You can keep a pair of quick-insert plugs on a cord around your neck. Or, get the Howard Leight Quiet Band QB2HYG. This is a plastic ring with earbuds, you can keep around your neck.
“Once a hunter is successful, the REAL work begins.” — Colton Reid
18. Harvesting the Animal — When dressing your animal, be careful with the meat. You’ll want very sharp knives. Some hunters prefer knives with replaceable, razor-sharp blades. Don’t rush the task. Make sure you don’t get moisture or dirt on meat. The three spoilers of meat are heat, moisture, and dirt.
19. Pace Yourself When Packing Out — If you DO succeed, and bring down a big buck, will you be able to dress the animal and carry out the meat? Always be prepared to hike out with extra weight. If you are successful, make sure not to waste the meat you worked so hard for. Choose a pack that can help you carry a heavy load. Remember, this is not an insignificant challenge — you may be carrying 60 to 100 extra pounds in addition to your other gear. Again, take your time. Rest as needed. Don’t hurt yourself.
20. Remember to Enjoy the Experience — Our Hunting Editor, Colton Reid, offers this sage advice to all hunters, but particularly to novices: “Have fun, and appreciate your hunt, whether you bag a buck or not. It is a privilege to experience the wilderness and to get away from the city. Enjoy it while you’re out there. And keep your spirits up. You may get tired, but remember that ‘comes with the territory’. At the end of the day, yes you may be exhausted. And you may want to quit and go home. But stay positive, stay focused. Be patient, the experience is worth it.”

Prepare For Your Hunt — Get Fit and Practice Positions
As part of the NRA’s Tips & Tactics video series, Kristy Titus explains how to prepare for a hunt. Titus, co-host of the Team Elk TV show has hunted around the globe. She grew up in the outdoors, running pack mules in Oregon with her father. In this video, Kristy discusses fitness training and demonstrates field positions that can be employed during a hunt.
Kristy explains: “Hunting can lead you into some steep, rough country. It’s really important that you train both your body and your mind to handle the elements and the rigors of hunting So, if you plan on going on a mountain hunt, get out and train your body. Train with your firearm. Get off the bench and have some fun with this. Do some positional shooting or, if you want to add a stress dynamic… have someone put you under a time parameter.”
