Hunting season is coming soon. For hunters that means many hours may be spent searching for animals through spotting scopes and binoculars — “glassing” for game. And when the hunter does find a good buck or doe, he’ll need to know the animal’s precise distance, so that demands a good laser rangefinder. Being carried in the field, the scopes on hunting rifles need to be tough and durable, and every hunting scope should have excellent low-light performance. And when the hunter finally takes his shot, his scope better be properly zeroed. Today’s Saturday showcase spotlights Hunting Optics. We offer seven good videos that help you select the right riflescope, spotting scope, rangefinder, and binoculars for your next hunt.
Optics Selections for Mountain Hunts
Here’s a good video by an avid hunter who treks in remote, mountainous zones. The host has learned what works… and what’s worth the weight to carry: “I’ve found that the combination of 10×42 binoculars and a 27–60x80mm spotting scope is the sweet spot for mountain hunting. This pairing balances weight with reach, allowing me to keep moving but also reach out and see well-hidden animals. In some cases, I will make use of an 18×56 binocular, but this is reserved for non-backpack hunts. With 25 years of mountain hunting experience, I can whole-heartedly recommend my preferred binocular pair as a fantastic and versatile set-up for northern mountain hunts at the very least.”
Ultimate Spotter Test — 19 Spotting Scopes Reviewed
The producers of this remarkable 19-product spotting scope comparison state: “If you are looking at choosing the best spotting scope for hunting… you are in the right place! We tested these 19 spotting scopes to find the best compact spotting scope, best 65mm spotting scope, and best 85mm spotting scope out there. We also wanted to find the best values on the market, and I think we definitely did that. While we certainly couldn’t test them ALL, we were able to put together this incredible lineup of some of the best spotting scopes out there to help you find what is going to work for your specific needs.”
First Focal Plane vs. Second Focal Plane Scopes
For the last century, Second Focal Plane (SFP) scopes have been most common on hunting rifles. Now there are an increasing number of First Focal Plane (FFP) optics favored by hunters. The main reason is that the reticle mark values (in Mils or MOA) are constant relative to the target size at all magnification levels. That is handy for hold-offs and hold-overs. On the other hand, a SFP scope maintains a constant reticle size and line thickness at all zoom values. For most hunting shots, taken inside 300 yards, that really should be fine. Many hunters feel they can spot their prey more easily without a busy reticle that obscures small details at higher magnification. This video explains the pros and cons of both reticle types. The final decision is up to you — much will depend on the terrain you hunt and the distances you shoot.
The Complete Optics Selection for For Deer Hunting
In this video, Vortex optics techs explain the optics package deer hunters will want to take into the field. Along with a good medium-power zoom riflescope, you’ll want binoculars and (probably) a spotting scope. You’ll also want a Laser Rangefinder (LRF) or laser-equipped binoculars. As the team points out, the LRF is not just to range your prey right before you take a shot. A top-quality LRF can range a reflective object as far as 1500 yards away. That helps you decide whether you want to hike a mile to reach that buck you see way out on the next ridge.
MOA vs. MIL — What You Need to Know
These days, scope manufacturers offer a wide selection of both MIL (Milliradian) and MOA (Minute-of-Angle) based optics. We do think that MOA is still predominant in the lighter-weight, lower-cost (sub-$500) scopes marketed for hunters. There are pros and cons for both angular measurement systems. One MIL is 3.6″ at 100 yards, while one MOA is 1.047″ at 100 yards. If you grew up thinking in inches, a 1/4-MOA click-value hunting scope might work best. If you shoot PRS or have other MIL scopes you may prefer a MIL-value optic for your hunting rifle. Both choices will do the job.
Comparison of Eight Laser Rangefinders
The Backfire team purchased eight rangefinders and tested them in the field. Most of the products are under $500. This is a good review if you are looking for a compact LRF at a moderate price. Looking at performance for the price, for the hunting market, the reviewers favored the Leupold RX-1600 and the waterproof Vortex Ranger 1800. COMMENTARY: If you can afford it, we recommend that serious hunters consider top-end laser rangefinder-equipped binoculars such as the ZEISS Victory RF and Leica Geovid.
How to Zero Your Hunting Rifle Efficiently
Last but not least, here’s a great video from Vortex that shows you how to quickly and efficiently sight-in and zero your hunting rifle before heading out into the field. This video explains a simple procedure that lets you get a solid zero in just three shots. Of course you probably want to fire a few more rounds to confirm your zero before you head off to your hunting grounds, but this will let you get on-target with a minimum amount of time and ammo expended. This helpful video has over 3 million views on YouTube!
Fouling Shots and Cold Bore Condition
If you recently cleaned your rifle, you may want to fire two or three fouling shots before you start this procedure. But keep in mind that you want to duplicate the typical cold bore conditions that you’ll experience during the hunt. If you set your zero after three fouling shots, then make sure the bore is in a similar condition when you actually go out hunting.
September 26, 2026 is National Hunting & Fishing Day. The annual celebration takes place on the the fourth Saturday of September every year. National, regional, state and local organizations will run thousands of “open house” hunting- and fishing-related events around the country. Events will include Fishing Derbys, Hunting Expos, Wing-shooting tournaments, and much more.
Hunting Safety Checklist
A good hunt begins with preparation. And during the hunt, safety is a key priority. To help hunters, the National Shooting Sports Foundation (NSSF) has created a Safety Checklist for hunters. This Hunting Safety Checklist, produced as part of the NSSF’s “Hunt S.A.F.E.” campaign, helps hunters follow good, safe practices in the field and at home.

Here is Tom Mousel with Whitetail taken with his ultra-light hunting rifle fitted with 6mm Creedmoor Lilja barrel. Friend Cody (right) actually took the shot. This gun has a second barrel in 6.5 Creedmoor.
Hunting season is opening up soon across the country. In just three weeks, on 9/26/2026, the nation celebrates National Hunting & Fishing Day. This Sunday we feature an impressive state-of-the-art, ultra-light hunting rifle. This rig is very accurate AND very light, and features two barrels, one in 6mm Creedmoor and the other in 6.5 Creedmoor. With this Titanium-actioned rifle, owner Tom Mousel has successful taken Whitetail deer and other game.
“Light is Right” when it comes to carrying deer rifles long distances in the backcountry. A lighter rifle DOES make a difference when you’re hiking many miles and carrying other gear including binoculars, laser rangefinders, food/water, and packs. And then, if you are successful, you’ll be carrying out game meat, so a lighter rifle translates to a lighter overall load.
When Forum member Tom Mousel (a top 1000-yard competitor) considered a new hunting rifle, he wanted a very light-weight rig. What he got was a low mass masterpiece — an ultra-accurate, five-pound hunting rifle. Not only does this twin-barrel rifle, as built by Alex Wheeler, come in under five pounds (before optics), but it has produced some quarter-MOA 3-shot groups at 1000 yards. The 6mm Creedmoor version of this rifle has demonstrated truly stellar accuracy at long range. The 6.5 Creedmoor barrel also shoots well and packs more punch for hunting use.
CLICK HERE to view full-screen large version of photo.
Here is Tom’s rifle weighing in at 4 pounds, 14 ounces with 21″ Lilja #1 contour 6mm barrel. Tom says: “Here’s the rifle with full Titanium action, bolt, and lug, in a Tom Manners 17 oz. carbon fiber stock. It’s exactly one pound heavier fitted with my Leupold Mark AR 4-12x40mm scope in Talley rings.”
Tom has two barrels for the rifle, one chambered for 6.5 Creedmoor and the other for 6mm Creedmoor. Tom reports: “The 6.5mm is a bit lighter being fluted. But I won’t be switching back now that I’ve shot the 6mm version. Neither has too much recoil, but the 6mm CM just kills the 6.5mm at distance for groups.”
Tom tells us: “What I like about this rifle is there were no corners cut to make it light. On some other ultra-lights, the fore-end has no strength or they are cut down really short. This is a full-sized stock, pillar-bedded with aluminum-filled epoxy and free-floated barrel. The ignition is set up with a TON of firing pin fall to function in the coldest temps.”
Gunsmith Alex Wheeler of Wheeler Accuracy is pleased with how this project turned out: “Tom has shot a bunch of sub-5″ groups and a couple one-inchers back-to-back at 1K. He has the Berger 115gr VLD going about 3050 fps.” Tom noted the 6mm barrel picked up about 50-60 FPS after the first 50 rounds. He shoots 115gr Berger VLDs with CCI 450s and Reloder 16, with the Bergers about .005″-.008″ in the lands.
Groups at 1000 Yards with 6mm Creedmoor Barrel, 115gr Bergers
Here are two of Tom’s 1000-yard targets. This is with the 6mm Creedmoor barrel shooting 115gr Berger VLDs pushed by Alliant Reloder 16 at about 3050 FPS. The average of the two groups is 0.246 MOA. Pretty amazing for an ultra-light rifle shot off a bipod. Tom acknowledges that he can’t do this every day. He says that “shooting 871 yards at my home range, the rifle typically shoots 4″ to 5″ 3-shot groups”.
Q & A with Tom Mousel About his Ultra-Light Hunting Rifle
Q: Why did you choose to build this rig?
Tom: I just wanted to do it to see how light we could build an accurate, good-shooting rifle.
Q: What are your favorite things about the rifle, and is there anything you would change?
Tom: Definitely the light weight, and the overall size — it has a pretty short barrel (21″), so it’s just handy. I wouldn’t change anything about the rifle, now that I have the Titanium bolt. When I bought the action originally it had the steel bolt.
Q: How does this rifle handle?
Tom: It points well considering it is a light rifle. The 6mm Creedmoor version has very little recoil. On a good bipod I can sight in at 1000 without a spotter.
Q: What are your favorite accessories?
I use a Solo Hntr Mtn Lite stretchy cover. You can see it in the photo at right showing me on a hunt. I like this because you can roll it up like a sock and and use it for a rear support.
Q: Why did you choose Alliant Reloder 16 powder?
Tom: Lonnie Anderson, a fellow Deep Creek shooter, did a 6mm Creedmoor and he said RL16 was absolutely the most accurate. We have also found that Reloder 16 is really consistent on velocities through the seasons — from 90 above to teens below zero.
Q: Could this ultra-light set-up work for a bigger caliber also?
Tom: I’ve tried bigger calibers, but I’ve never been satisfied with the consistency of the groups. There’s a cut-off — there’s too much torque and recoil. We see a limit — you don’t want “too much gun” for the platform. Even here, the 6.5 barrel just doesn’t shoot as well as the 6mm.
Q: What advice do you have for hunters considering ultra-light rifles?
Tom: Be careful about falling in love with ballistics and trying to build too much bang for too small a platform. If I built a 7mm WSM for example, I’d want to rifle to weigh at least two pounds more.
Full Titanium Action from Pierce Engineering
This photo shows the Pierce Engineering Titanium Featherweight short action featuring Titanium (Ti) receiver, Ti bolt, and Ti lug. This unit is a mere 15.90 ounces complete. (NOTE: with Titanium body and STEEL bolt the weight is 18.5 ounces). The long action version is 17.4 ounces for the complete Titanium action with Ti bolt and Ti lug.
Jud at Pierce Engineering tells us: “Both the Ti action body and Ti bolt are DLC-coated. This action also has an anti-bind rail for added smoothness and ease of functioning. This really is one of the lightest actions on the market. If you’re looking into building an ultra-light rifle I would seriously check one out! We make these with the highest level of detail, pride, and machining tolerances. They’re just sweet actions… and our Ti Featherweight short action is roughly half the weight of a Remington Model 7. So there’s a significant weight savings with the Pierce Ti Featherweight over a Model 7.”
Owner Profile — Tom Mousel, Hunter AND Long-Range Benchrest Ace
Tom Mousel knows a few things about accurate rifles. He is a top 1000-yard competitor at IBS matches and at the Deep Creek range near Missoula, Montana. In 2016 Tom set a remarkable 6-match Light Gun Group World Record, with a 2.9540″ group size Aggregate for SIX matches. And a year later, in 2017, Mousel set a 10-Match Heavy Gun World Record with a 5.3376″ Aggregate. NOTE: that is for TEN-shot groups in Heavy Gun. That’s an average ten-shot group under 6 inches for 10 matches! Over the past decade, Tom has remained at the top of the 1000-yard game, with many match wins at Deep Creek and other ranges.
Keith Glasscock is an outstanding competitive shooter, who has finished second at the F-Class National Championships (F-Open) multiple times. Keith is also a skilled wind coach who runs the popular Winning in the Wind YouTube Channel. Along with his interest in F-Class competition and (recently) PRS/NRL competition, Keith also enjoys game hunting and varmint adventures.
Hunting season is coming soon, so today we showcase two videos Keith has made about developing hand-loads for hunting rifles. Developing accurate hand-loaded ammo for hunting and varmint rifles involves procedures that may be a bit different than load testing for a match rifle. You want to be efficient, and use the types of brass and bullets you’ll be using on the hunts. In these two videos, Keith shows how he developed good, accurate loads for a .223 Rem varmint rifle and a .308 Win hunting rifle.
In addition to Keith’s two informative videos, today we feature three other videos with useful tips and techniques for hunters and huntresses. These cover rifle marksmanship, hunting optics selection, and methods for sighting-in hunting rifles.
.223 Rem Load Development — Powder Charge and Seating Depth
In the first video, Keith covers the load development process for a Remington 700 bolt-action varmint rifle chambered in .223 Remington. Keith starts by full-length sizing the brass. Then he experimented with powder charge weights, and came up with a promising load of 24.7 grains of Alliant AR Comp with Hornady 50gr A-Max bullets.
Next Keith experimented with seating depths (see 5:30-6:100) and found that accuracy improved as he changed OAL length in .005 increments. Keith ended up with 2.270″ with a 3-shot group in the twos! This video shows the importance of testing your bullet choice at various seating depths. Keith shoots this rig prone off bipod, which is similar to the bipod shooting he does in the varmint fields. Keith explains key factors to consider when optimizing the .223 Rem cartridge in a varmint rig. Velocity readings are made with a LabRadar unit.
Load Development for .308 Win Hunting Rifle
In a second video, Keith shows the process for load development with a .308 Winchester hunting rifle. Here Keith uses a large X-type sandbag for a front support. Again, he was shooting a Remington 700 bolt-action rifle, this time with Barnes TSX solid copper bullets, PPU Brass, Federal 210m primers, and AR Comp powder. Keith said the Barnes bullets were excellent — he commented that these bullets were “match quality in terms of precision”. Keith achieved some very small three-shot groups with AR Comp and the TSX projectiles. Keith did note that point-of-impact shifted up significantly with increases in charge weight (see 6:20-7:10). With thinner-contour hunting barrels, this is not unexpected. But POI change should be observed carefully during load development, as you may need to adjust your zero after completing testing.
Three Bonus Videos for Hunters and Huntresses
Here are three videos with useful tips and techniques for hunters and huntresses. These cover rifle marksmanship, optics selection for deer hunting, and efficient methods for sighting-in hunting rifles.
How to Shoot Better with a Hunting Rifle
This “must-watch” video has great practical advice for hunters. It illustrates proper hand-hold and head position, and shows how to stay steady when breaking the shot. Even competition shooters can learn a few things. One viewer notes: “This was very informative. The footage through the scope showing how one’s position moves the sight alignment was particularly helpful.”
You’ll find more great videos on Thomas Haugland’s THLR.NO YouTube Channel, that offers videos for long-range hunters and marksmen. Haugland, who hails from Norway, is a serious shooter, who takes his rifles out into the field, in all conditions. The THLR.NO channel offers solid advice on scopes, reticles, wind-reading, field positions, and much more. Haugland’s team puts a wide variety of gear through serious field tests — every thing from suppressors to packs to electro-optical hardware. In addition the THLR.NO channel provides good advice on stalking techniques and hunting skills.
The Complete Optics Selection for For Deer Hunting
In this video, Vortex optics techs explain the optics package deer hunters will want to take into the field. Along with a good medium-power zoom riflescope, you’ll want binoculars and (probably) a spotting scope. You’ll also want a Laser Rangefinder (LRF) or laser-equipped binoculars. As the team points out, the LRF is not just to range your prey right before you take a shot. A top-quality LRF can range a reflective object as far as 1500 yards away. That helps you decide whether you want to hike a mile to reach that buck you see way out on the next ridge.
How to Sight-In Your Hunting Rifle
This video offers good basic advice for sighting-in a hunting rifle. There are a series of six points covered. Here’s Tip #1: “Find a safe place to shoot your rifle with a backstop. If possible, use a bench and a rock-solid shooting rest. Sighting-in is all about consistency, so the less human error you have, the better. For safety, be sure to also bring ear and eye protection.” READ FULL ARTICLE on NRAWomen.com.

Will you be heading to the varmint fields this summer? Proper planning is key to a safe, satisfying, and productive varmint holiday. Bring a variety of rifles if possible — you’ll need to switch off as one barrel gets hot, and the chambering that works best for your close shots may not be ideal for those longer shots out past 400 yards. Here’s one tip that can help you shoot more effectively on your varmint hunt — at your shooting station, put a strip of surveyor’s tape on a tall stake to show the wind direction. Then align to the wind direction, so that it is a direct headwind or tailwind. This will minimize the effect of cross-winds.
For fans of varmint hunting, we’ve assembled eight videos for this Saturday at the Movies Feature. You’ll see a variety of rifles being used in classic American varmint country — Montana, Oregon, and the Dakotas. We’ve also included an interesting video from South Africa.
Extreme Outer Limits — Oregon Adventure with .22 Creedmoor
This varmint safari video features the Extreme Outer Limits squad in Central Oregon. The host is shooting the .22 Creedmoor cartridge from a 22″ Benchmark barrel. The shooters benefit from a great operation, with elevated mobile shooting stations and benches. Watching this video made this Editor want to travel up to Oregon this summer, and try out a .22 Dasher that’s been sitting in the safe.
This video has plenty of action, with hits on small varmints (mostly ground squirrels) out to considerable distances. You can see the effectiveness of the .22 Creedmoor cartridge — it basically vaporizes some of the critters.
.22-250 Nails Ground Squirrels and Rock Hyraxes in South Africa
Here’s an interesting video from South Africa. The video maker starts with shots on ground squirrels. His .22-250 blasts them into little pieces. They he switches to more distant targets, a furry ground-hog size animal called the Rock Hyrax, Cape Hyrax, or Dassie. Mature Rock Hyraxes weigh 4-5 kilograms and have short ears and tail. These Rock Hyraxes are found at higher elevations in habitats with rock crevices, allowing them to escape from predators (but not skilled varmint hunters).
1125-Yard Rockchuck Hit with Extreme Outer Limits
Here a team from Extreme Outer Limits tests their skills at Extreme Long Range Varminting. The group set up benches and aim their rifles at a distant hillside over 1100 yards away. You can see a successful first-shot rockchuck hit at the 5:15 time-mark. On this episode of Extreme Outer Limits, Bob Beck, Tim Titus, and some MOA Rifles clients to put the .22 Creedmoor and other MOA-brand rifles to the test. At these long distances, Rockchucks are relatively small targets providing plenty of challenge.
Long Range Rockchuck Adventure with Gunwerks Crew
This Gunwerks video showcases varmint hunting in the Western USA. In this video Aaron Davidson and the Gunwerks crew try out some new rifles on some rockchucks. Most of the the rifles were suppressed but the host said the rockchucks took cover after the first shot, so this required good coordination among shooters and spotters. A 6XC varminter is featured at 2:44 and there’s some nice drone footage starting at 2:00.
Varminter.com — Great Resource for Varmint Hunters
Varminter.com is a great resource for serious varmint hunters. This site regularly reviews rifles, optics, and varmint ammunition. In addition, the site’s founder, Eric Mayer, often ventures out in the backcountry to film his varmint adventures.
Varminting with .17 HMR Savage A17 and Custom .17 WSM AR
On varmint excursions, we like to have a .17 rimfire for the closer shots, inside 150 yards. This video shows a successful Prairie Dog hunt with a .17 HMR. Watch and you’ll see hits out to 160 yards (00:50), proving the effective range of the .17 HMR cartridge. The host is shooting a Savage A17 semi-auto 17 HMR rifle in a Boyds laminated stock.
Varminters now enjoy three .17-caliber rimfire options. The .17 Mach 2, .17 HMR, and .17 WSM are all good choices, with the 17 Mach 2 being the cheapest and the .17 WSM the most powerful. With a rimfire you save on ammo costs and you don’t waste precious centerfire barrel life. Also the noise is reduced so you don’t spook the critters so much. We have shot ground squirrels with both the 17 HM2 and .17 HMR. And with a 3000 fps MV, the .17 WSM has some really impressive ballistics. As you can see, the .17 WSM has a much flatter trajectory than both the .17 HMR and .22 WMR:
Last but certainly not least, this video from Eric Mayer, founder of Varminter.com and AR15Hunter.com. This video features an innovative AR-platform rifle chambered for the potent .17 Winchester Super Magnum (aka .17 WSM) cartridge. Eric was able to have instant kills out to 200 yards. This rifle features a Franklin Armory F-17 V4 upper with a Franklin Armory 10-rd magazine. Eric was very impressed with the .17 WSM and he believes the 20gr bullet with 3000 fps MV will be very effective for most of his small varmint hunting out to considerable distances.
KILL Shots — BONUS Age-Restricted Videos
Linked below are a couple very good varminting videos that show explosive hits. However, YouTube has decided these can’t be posted on third-party websites so you’ll have to click the links below to see the Prairie Dogs going airborne. In the first video, the lady shooter nails THREE P-Dogs with one shot!
1. Eastman’s Hunting Journals. Great Video from Eastern Montana. This has nice Aerial Footage and an amazing shot with three P-dogs (in line) dropped with a single shot (at time-mark 9:28). One shot — THREE prairie dogs down! This prairie dog hunt features slow-motion kill shots, digiscope close-ups, and a rare prairie dog triple kill. A group of hunters works to remove prairie dog pests from private grazing lands in this episode of Beyond the Grid by Eastmans’ creators of Eastmans’ Hunting TV.

“A bullet launched at a higher altitude is able to fly slightly farther (in the thinner air) for every increment of downward movement. Effectively, the bullet behaves as if it has a higher ballistic coefficient.”
A few seasons back a good friend ventured to the high country of Colorado to pursue elk. He recently zeroed his rifle in California, at a range just a few hundred feet Above Mean Sea Level (AMSL). He wondered if the higher altitude in Colorado could alter his ballistics. The answer is a definite yes. However the good news is that free ballistics calculators can help you plot reliable drop charts for various shooting locations, high or low.
The question has been posed: “What effect does altitude have on the flight of a bullet?” The simplistic answer is that, at higher altitudes, the air is thinner (lower density), so there is less drag on the bullet. This means that the amount of bullet drop is less at any given flight distance from the muzzle. Since the force of gravity is essentially constant on the earth’s surface (for practical purposes), the bullet’s downward acceleration doesn’t change, but a bullet launched at a higher altitude is able to fly slightly farther (in the thinner air) for every increment of downward movement. Effectively, at higher altitudes, the bullet behaves as if it has a higher ballistic coefficient.
Forum member Milanuk explains that the key factor is not altitude, but rather air pressure. Milanuk writes:
“In basic terms, as your altitude increases, the density of the air the bullet must travel through decreases, thereby reducing the drag on the bullet. Generally, the higher the altitude, the less the bullet will drop. For example, I shoot at a couple ranges here in the Pacific Northwest. Both are at 1000′ AMSL (Above Mean Sea Level) or less. I’ll need about 29-30 MOA to get from 100 yards to 1000 yards with a Berger 155gr VLD at 2960 fps. By contrast, in Raton, NM, located at 6600′ AMSL, I’ll only need about 24-25 MOA to do the same. That’s a significant difference.
Note that it is the barometric pressure that really matters, not simply the nominal altitude. The barometric pressure will indicate the reduced pressure from a higher altitude, but it will also show you the pressure changes as a front moves in, etc. which can play havoc w/ your calculated come-ups. Most altimeters are simply barometers that read in feet instead of inches of mercury.”
As Milanuk states, it is NOT altitude per se, but the LOCAL barometric pressure (sometimes called “station pressure”) that is key. The two atmospheric conditions that most effect bullet flight are air temperature, and barometric pressure. Normally, humidity has a negligible effect. It’s important to remember that the barometric pressure reported on the radio (or internet) may be stated as a sea level equivalency. So in Denver (at 6,000 feet AMSL), if the local pressure is 24″, the radio will report the barometric pressure to be 30″. If you do high altitude shooting at long range, bring along a Kestrel, or remember to mentally correct the radio station’s pressure, by 1″ per 1,000 feet.
Trajectory of Bullet fired at Sea Level
Trajectory of Bullet fired at 20,000 feet
You can do your own experimental calculations using Berger Online Ballistics Calculator (free to use). Here is an extreme example, with two printouts (generated using Point Blank software), one showing bullet trajectory at sea level (0′ altitude) and one at 20,000 feet. For demonstration sake, we assigned a low 0.2 BC to the bullet, with a velocity of 3000 fps.
To learn more about all aspects of Exterior Ballistics, Hornady has a useful discussion of External Ballistics including the effects of altitude and temperature. There is also an online archive with detailed information from Sierra’s Exterior Ballistics Resource Page. This web archive features multiple sections from the Sierra Manual (4th and 5th Editions), including:
Section 3.0: Exterior Ballistic Effects on Bullet Flight
Section 3.1: Effects of Altitude and Atmospheric Conditions
Section 3.2: Effects of Wind
Section 3.3: Effects of Shooting Uphill or Downhill
Example from Section 3.0: “When a bullet flies through the air, two types of forces act on the bullet to determine its path (trajectory) through the air. The first is gravitational force; the other is aerodynamics. Several kinds of aerodynamic forces act on a bullet: drag, lift, side forces, Magnus force, spin damping force, pitch damping force, and Magnus cross force. The most important of these aerodynamic forces is drag. All the others are very small in comparison when the bullet is spin-stabilized.”
Q: Why did you choose to build this rig?
This varmint safari video features the Extreme Outer Limits squad in Central Oregon. The host is shooting the .22 Creedmoor cartridge from a 22″ Benchmark barrel. The shooters benefit from a great operation, with elevated mobile shooting stations and benches. Watching this video made this Editor want to travel up to Oregon this summer, and try out a .22 Dasher that’s been sitting in the safe.
The question has been posed: “What effect does altitude have on the flight of a bullet?” The simplistic answer is that, at higher altitudes, the air is thinner (lower density), so there is less drag on the bullet. This means that the amount of bullet drop is less at any given flight distance from the muzzle. Since the force of gravity is essentially constant on the earth’s surface (for practical purposes), the bullet’s downward acceleration doesn’t change, but a bullet launched at a higher altitude is able to fly slightly farther (in the thinner air) for every increment of downward movement. Effectively, at higher altitudes, the bullet behaves as if it has a higher ballistic coefficient.
