Speed Up Bore Cleaning Tasks with Wash Bottles

bore cleaning Wash Bottle

rifle bore cleaner bottleSmall patches are not very efficient at distributing bore cleaning liquids inside your bore. The problem with a tight-fitting patch is that the solvent gets squeezed off in the first few inches. You can switch to a smaller jag, or a bore mop, but there is an even better way to get an ample amount of solvent in your bore. Just spray directly into the bore with a wash bottle, an inexpensive plastic bottle with an L-shaped dispensing neck, tapered at the end.

When using the wash bottle, you can either just plug the breech and spray from the muzzle end (where most copper fouling is), or, alternately, put the wash bottle neck directly in the chamber and spray forward. When spraying from the chamber forward, you may need to use a rubber O-Ring to seal off the action… depending on the bore size and the particular wash bottle’s neck spout diameter. We prefer to plug the breech and squirt from the muzzle.

Bottle Solvent Application Method Works Great for Smaller Bores
Using wet patches or wet brushes is an inefficient way to really saturate the tight bores of 17s, 20s, and 22s. Even with a cotton bore mop, most of the solvent will be squeezed out before it gets to the end of the bore, where most copper fouling occurs. For these smaller 17, 20, and 22-caliber bores, you can just take the wash bottle and stick the tapered nozzle right in the chamber. The tapered end will press fit in the throat, sealing off the chamber. With the barrel slightly nose-down, give the bottle a couple good squirts until the solvent mists out the muzzle. In just a few seconds, this will put more solvent in the bore than a half-dozen wet patches.

A solvent-filled wash bottle is also handy for wetting your brushes. It’s much easier to saturate a bore brush (without spilling solvent on your stock), by using the wash bottle. You can get wash bottles from USPlastic.com, Amazon.com, or lab supply stores. CLICK HERE for $4.98 wash bottle.

Norma Ammunition Factory — Cartridge Creation Start to Finish

Norma has released a fascinating video showing how bullet, brass, and ammunition are produced at the Norma Precision AB factory which first opened in 1902. You can see how cartridges are made starting with brass disks, then formed into shape through a series of processes, including “hitting [the cup] with a 30-ton hammer”. After annealing (shown at 0:08″), samples from every batch of brass are analyzed (at multiple points along the case length) to check metal grain structure and hardness. Before packing, each case is visually inspected by a factory worker.

The video also shows how bullets are made from jackets and lead cores. Finally, you can watch the loading machines that fill cases with powder, seat the bullets, and then transport loaded rounds to the packing system. Guys, watch this video! You won’t be disappointed. The camera work and editing are excellent — there are many close-ups revealing key processes such as annealing and head-stamping.

The Manufacturing Process for .22 LR Rimfire Ammunition
Shooting Sports USA explains: “Rimfire cartridge cases are the oldest self-contained cartridge in existence, having been in continuous production since the mid-1850s. Rimfire cases are drawn from a thin piece of brass and formed with a hollow rim. A priming compound is then forced into the case using centrifugal force, where it is charged with powder and a bullet is seated in the mouth of the case. The case is then crimped around the bullet to ensure sufficient push and pull when the round is fired. When the firing pin strikes the thin brass rim of the case, the hollow rim is crushed and the primer is ignited.” Source: SSUSA.org 9/2/2017.

How to Dry Brass After Wet Tumbling or Ultrasonic Cleaning

Wet Tumbling Brass Drier

Many shooters these days clean their cartridge brass ultrasonically, or wet-tumble their cases with stainless media (above). Both methods get brass clean and shiny, inside and out. However, when those wet-cleaning processes are completed, you’re left with a pile of soaking wet brass. How do you dry your brass quickly and efficiently, without unsightly water spots? Read on for some great answers…

In our Shooters’ Forum, Member Terry asked: “How do you dry your brass after Ultrasonic cleaning?” In a Reloading Forum Thread, many smart suggestions were posted. A dozen fellow members outlined a variety of effective case-drying procedures, which work equally well for both wet-tumbled brass and ultrasonically-cleaned cases. Here are the Top 10 brass-drying suggestions from our Forum members.

TOP TEN Ways to Dry Cartridge Brass After Wet Cleaning

1. Food Dehydrator — Shake the brass in towel to get the bulk of water off. Next leave in the food dehydrator for 45 minutes or until there are no signs of moisture inside the cases. — Lawrence97

2. Lyman 5-Level Case Dryer — Rinse off cleaning solution(s), then load brass by type into racks in Lyman Cyclone Case Dryer. This is easier to load/unload than food dehydrators and holds more cases.

Lyman Cyclone Case Drier

3. Hot Water + Compressed Air — Rinse all your cases as a batch using scalding hot water from the kitchen sink. Hot water evaporates off of brass very very quickly. Then hit them with compressed air. Takes 10 minutes. Simple. — SG4247

4. Oven Dry in Pre-Heated Oven — After pre-heating to 200° or so, turn off oven and put brass inside on a tray. Most important! Tell your wife what you are doing so she doesn’t crank it up to 425 to heat pizza! — MClark

NOTE: Many other members suggested oven drying at 150-200°. We recommend turning OFF the oven so you don’t cook your brass if you forget to remove the cases.

Dry Cartridge Brass heat gun5. Towel Dry then Warm with Heat Gun — Roll brass in a towel until no more water shakes out. Lay out on cardboard box top and blow off with Harbor Freight heat gun. $9.99 on coupon. Two minutes of heated air and about half hour of wait and they are good to go. This is with primers removed. — Shaggy357

6. Compressed Air, then Sun Dry Outside – I rinse the brass, then blow them out with compressed air. Then, dependent on the time of year, lay them on a towel in the sun. — HogPatrol

7. Dishwasher on Dry Cycle – In the winter, I drop my wet brass cases neck-down on the rack pegs in the dishwasher, then turn on the dry cycle. In the summer…well, I’m in Texas. They go to the porch for a bit. — Toolbreaker

8. Alcohol Rinse then Air or Oven Dry — Rinse in 90% Isopropyl alcohol and either let air dry or stick in 175° oven for half an hour. Alternatively, use a dehydrator. — Zipollini

9. Slow Air-Dry in Loading Blocks — I have a reloading block with holes drilled in it. I simply load the block up and let it air-dry in the cupboard for a couple of days. — JCS

10. Wipe with Towel Then Anneal Normally with FLAME Annealer — This thread is stirring my OCD side. Seems complicated for just drying — my brass dries just fine when I anneal it. This entire process can’t take an hour per batch. When finished, the brass is cleaned, annealed, and ready to size. — CHLuke
NOTE: This is NOT recommended for use with electronic AMP annealers. Use this ONLY with flame annealers.

  • Deprime, then tumble brass with stainless media, water, Lemishine, and dish detergent.
  • Shake them easily in a strainer to knock out most media then grab 4-5 pieces, shake them over the bucket for the last of the media then inside a towel.
  • Finally blow out the primer pockets and wipe with a towel, load in the Annealeez flame annealer.

Modern-Day Annie Oakley — The Talented Kirsten Joy Weiss

Kirsten Weiss trick shot Annie Oakley NRA All access

Talented sharpshooter Kirsten Joy Weiss is featured in an episode of NRA All Access. The show covers Kirsten’s development as a competitive shooter, and her success as a trick-shot artist with her own popular YouTube channel. Here’s the All Access segment featuring many of Kirsten’s most famous trick shots.

During the video Kirsten also talks about her background in shooting and how she wants to be a good ambassador for the shooting sports, “spreading the positive reality of shooting”. Kirsten explains: “The fun challenge and joy of shooting is important to me because I really wanted to be a positive example. So when the media says the ‘guns are a bad thing and nobody does anything good with guns’, they can say ‘Well, what about her [Kirsten]’?”

Kirsten: “I think that it’s important for young girls to have somebody that they can look up to… I feel responsibility to show young shooters coming up, especially females, that you can respect yourself and shoot a gun as well.”

Kirsten Joy WeissA gifted “natural” shooter, Kirsten started shooting fairly late — at age 16. Despite her relatively late start, she learned very quickly, and managed to earn a place on the University of Nebraska shooting team. That literally opened up a new world for Kirsten: “During the course of my career, I’ve had a lot of success. I’ve gone to World Cups… in Zagreb, Croatia, in Munich, Germany. I’ve won National Championships, and got on to the U.S. Olympic short list, so it’s been a good career.”

Proper Cheek Weld

No matter what your discipline — smallbore, silhouette, High Power, F-Class, or even PRS — it’s vital to have a consistent cheek weld for every shot. You want your head to be in the same position on the stock each time. This helps ensure proper eye-to-sights/optic alignment and consistent rifle balance.

In this video, Kirsten explains how to find the best position for your head on the stock, which may require adjusting the cheekpiece and/or length of pull. Then Kirsten demonstrates how to maintain consistent cheek weld shot after shot.

Kirsten tells us: “A lot of people don’t think of shooting as a sport, but it absolutely is, and I would even go so far as to say that it is an art form.” We don’t know if this is art, sport, or magic, but very few shooters have the skill or flexibility to make this upside-down shot…

How to Correct Common Handgun Malfunctions — Key Advice

pistol handguns semi-auto hang fire misfeed double feed stovepipe squib load

The Cheaper Than Dirt Shooter’s Log has a very helpful article for pistol shooters. This CTD article identifies five common malfunctions in semi-auto pistols, and explains how to deal with the five issues safely.

This can be very important — even life-saving. For example, with a hang fire, i.e. a round that does not fire immediately, it is vital to keep the gun pointed DOWN-RANGE. And with a squib load, which may have left a round inside the barrel, it is vital to UNLOAD and NOT take another shot! If you did, the gun could blow up in your hand when the second, full-charge bullet hits the trapped bullet.

The Five Topics Covered Are:

Misfeed (aka Tip-Up)
Double Feed

Stovepipe (Failure to Extract)
Misfire / Hangfire

Squib Load

1. Misfeed or Tip-Up: With any misfeed you should stop firing. With the muzzle pointed safely down-range, remove the magazine, then pull the slide back and remove the round that did not feed. Check the slide for dirt, debris, and check the round that did not feed. After re-inserting the magazine, make sure the mag is seated properly.

2. Double-Feed: This is a fairly common issue with some gun types with worn springs or cheap magazines. Again you want to remove the magazine. CTD states: “Remove the magazine and cycle the action until your double-fed rounds fall out — always keeping the muzzle pointed in a safe direction[.]”

3. Stove-Pipe: This occurs when the case of a fired round does not eject fully. There can be many causes — damaged extractor, low-pressure powder charge, dirty chamber, or greasy cartridge brass. In addition the issue is common with old, worn-out recoil springs. To avoid Stove-Pipes, replace the recoil spring every 4000 rounds, and make sure your chamber is clean and the extractor is not chipped or damaged.

4. Misfires and Hang-Fires: There are multiple causes for misfires (“click no bang”) and hang-fires (slow ignition). There can be a defective primer, the firing pin could be damaged, the powder many have been bad, or the case not filled properly. With a misfire, keep the gun pointed down-range at least one minute. If the case does not fire, eject it but leave it on the ground. With a hang-fire (delayed ignition after firing pin strike), keep the gun pointed down-range, then drop the magazine and eject the (new) unfired cartridge in the chamber and inspect the gun when completely empty.

5. Squib Load: A squib load is when the gun fires, but the actual case ignition is very light with little noise, smoke, or recoil. This can be because the case had a primer but no powder. Or it can be because the powder did not ignite. Squib loads can be very dangerous in rapid-fire situations. If you EVER get a squib load STOP immediately! Do NOT fire another round! This is because the squib may have left a bullet inside the barrel.

Bullet Flight Video Shows Bullet Shock Wave and Base Drag

Science Accuracy Academy bullet video Schlieren movie shock wave capture

Ever wondered what the air around a moving supersonic bullet really looks like? Check out this video from the Bryan Litz Ballistics Facebook page. This is a Schlieren video* of a 6mm 109gr Berger LRHT bullet at about 2800 fps as fired from Francis Colon’s PRS rifle at the Applied Ballistics Lab.


Bryan Litz notes: “You can clearly see the compression (shock) wave at the front of the bullet. A compression wave is formed when the air has to move faster than the speed of sound to get out of the way, which is certainly the case for this bullet which is moving about 2.5 times the speed of sound (Mach 2.5).

That shock wave is the ‘snap’ you hear when bullets fly past you if/when you’re downrange. Also, compressing the air into a shockwave takes energy, and that energy comes directly out of the forward velocity of your bullet and gets converted into heat and noise as the shock wave forms and dissipates.

The turbulent wake at the base of the bullet shows where/how base drag applies. The third and smallest component of drag for a supersonic bullet is skin friction drag, which is a viscous boundary layer effect, and is the least visible in this image. So as you head to the range or the hunting stand, think about the absolute violence your bullets are committing in the atmosphere, before they even reach the target!”

Marksmanship Skills — Optimal Finger Placement on Trigger

kirsten joy weiss trigger placement shooting skills

You can spend thousands on a rifle, but that expensive hardware won’t perform at its best if you have poor trigger technique. One key element of precision shooting is trigger control. Our friend Kirsten Joy Weiss has produced a good video that shows how to refine your trigger technique for better accuracy. In this video, Kirsten talks about the actual placement of a shooter’s index finger on the trigger. It is important to have the finger positioned optimally. Otherwise you can pull the shot slightly left or slightly right.

Kirsten tells us: “Finger placement on the trigger might not seem like a big deal, but it actually is. The reason for this is because, depending on where your index finger is placed on the trigger, [this] translates to different muscle interactions with the gun.” Watch this video to see Kirsten demonstrate proper finger placement (and explain problems caused by improper finger positioning).

When you pull the trigger, you only want to engage the last section of your finger, in order to avoid unwanted muscle engagement and to achieve a smooth shot. Remember there is a “sweet spot” between the crease (first joint) and the tip of the finger. If you position the trigger in that “sweet spot”, you should see an increase in your accuracy. Don’t make the mistake of putting the trigger in the crease of your finger, as shown below.

kirsten joy weiss trigger placement shooting skills

Effects of Incorrect Finger Placements
You want to place the trigger shoe between the end of your finger and the first joint. If you place the trigger on the very tip of you finger you’ll tend to push the rear of the rifle to the left when engaging the trigger, causing shots to go right (for a right-handed shooter). On the other hand, if you put the trigger in the crease (first joint), you’ll tend to bring the rear of the rifle to the right, causing shots to fall left. This is illustrated below for a right-handed shooter.

Shooting at Indoor Ranges — Tips for Proper Range Procedures

Safety Video NSSF Indoor Range Etiquette

Shooting indoors is fun, and at many indoor ranges you can shoot in the evening after work. But when shooting indoors you should always be extra careful. Follow all key gun safety practices and adhere to proper range “Etiquette”. We also recommend double hearing protection — plugs under muffs.

The NSSF (NSSF) offers a useful Range Safety and Etiquette video. This 8.5-minute video explains safe practices, especially at indoor ranges. In the video, the moderator list the basic rules of gun safety, before covering key range etiquette topics such as range officer commands, how to uncase your firearm on the range when you first arrive, and what to do if a firearm is accidentally dropped. There are also safety tips specific to handling both semi-automatic handguns and revolvers.

Safety Video NSSF Indoor Range Etiquette

BAD RANGE BEHAVIOR — Five Things NOT to Do at the Range

Here are the five worst behaviors we’ve seen at indoor ranges. These behaviors are both dangerous and inconsiderate. Any one of these behaviors can get you permanently banned from an indoor range.

1. Sweeping other individuals after loading a weapon behind the firing line is very bad. All your weapons should be empty until you reach your shooting station.

2. Turning the handgun sideways while trying to clear a malfunction or insert/remove a magazine. This will point the muzzle at a fellow shooter. Or, after shooting a gun, the shooter fails to clear the weapon and then places the gun somewhere near the shooting station with the muzzle in an unsafe position.

3. Reacting unpredictably when firing a high recoil handgun. We’ve seen people take a second shot by accident with the muzzle way off target.

4. Not obeying range commands — in particular continuing to shoot during called cease-fires.

5. Poorly aimed shooting that hits target frames or carriers, causing ricochets.

Seven Types of People at the Gun Range — HUMOR

This video is satire, but with lots of truth in the characterizations. Laughter guaranteed.

Double-Up on Hearing Protection When Shooting Indoors

Howard Leight Impact Pro Electronic Muffs NRR 30

When shooting rifles and pistols indoors we recommend quality muffs with earplugs underneath, offering double protection. When inside an enclosed range, with other shooters blasting away right next to you, you really need effective hearing protection. But you also need to hear range commands and be able to communicate with your fellow shooters. That’s why we recommend electronic muffs with plugs underneath.

Saturday Movies — Five Great 3D Animations Look Inside Guns

Saturday movies Matt Rittman 3D animation AK47 AR-15 Glock 19 M16 bolt-action pump-action computer graphics Kar 98-K modern sporting rifle

409,000,000 views! Today’s five feature videos have, collectively, been viewed 372 million times on YouTube. Today’s Saturday special features five remarkable animated firearms videos from Matt Rittman, a very talented computer graphic artist. Matt employs multiple software programs to create these incredibly detailed animations. His software tools of the trade include Cinema 4D, Substance Painter, and Corona renderer. Don’t think this is easy. Some of these videos took over 500 man-hours to create. Enjoy!

AR-15 Full Animation — Components and Function

While there are other AR-15 animations on YouTube, we think this is the most accurate and creative, showing the function of a wide variety of components, including the bolt carrier, extractor, trigger, stock buffer, safety system, forward assist, and mag release. It also shows modes of a military M16, showing 3-round burst fire, and full-auto, employing disconnectors and auto sear. If you are planning to assemble/disassemble an AR, this is definitely worth watching start to finish. This video has recorded over 2 million views in just three weeks!

Glock 19 (Gen 4) — Inside and Out and Function

This 3D animation video shows the popular Glock 19 (Gen 4) pistol. This modern, polymer-framed, striker-fired pistol has constant trigger pull for all shots. Some folks call this a DAO (double-action-only) trigger but that’s not really correct. Unlike the Model 1911, on a Glock there is no external safety on the frame or slide. The trigger “shoe” (the part that contacts finger) includes a central blade. This prevents the gun from firing unless the trigger is depresses normally. Glock calls this the “safe action”. The creator, Matt Rittman states: “Cinema 4D was used to create each individual part, as well as animating everything. Substance Painter was used to create the main textures. Corona renderer was used to render everything. This animation [with 84.6 million views] took me over 500 hours to create.”
