IMO, there is a fundamental flaw with so called "biodegradable" gun products. All of the ones I am familiar with degrade by oxidizing. This turns them into gummy residue over time.
Firearms are often stored for extended periods between uses and not subject to periodic maintenance. Many of...
Redline Racing oil. I like the 15-50W. I've been using it for about fifteen years. It is a group V ester based synthetic oil that gives absolutely top tier EP lube, stays put for months, will never gum up and provides adequate corrosion protection...
I think "in your face" behavior is counter productive for any cause. Discrete OC is OK by me but flaunting the fact one has a firearm is a bad idea IMO for several reasons including personal safety of the carrier. I doubt many "open carriers" have any training in firearms retention. They may...
The Cirello (sp) articles I have read said the stake out squad preferred the M1 carbine. They often only had partial head targets and they had problems with bullets skirting the scalp and failing to stop. Jim concluded the full wad cutter profile worked best for their purposes and even had a...
A bore Snake to clean the chamber and a stiff tooth brush (spring for a new one) to clean the bolt face and the extractor is what I use about every fifty rounds on semi-autos. Closed bolt guns can usually go quite a bit longer. Cold weather requires cleaning more often than warm.
Cleaning...
223 VS 5.56 refers to the chamber dimensions not the bore diameter. 5.56 has a longer lead (and other minor dimension differences) which allows higher pressure ammo to be fired.
1/9 barrels are "iffy" for good accuracy with bullets heavier than about 60gr. Heavier bullets can work well but...
You have to depress the "button" until the inside plate the spring rests on is permanently forced to the side. It has to be either at about 45* or twisted sideways so it doesn't interfere with the compression of the sides of the mag. Then if you insert a standard Glock tool all the way into...
If I were to own one handgun for general use I would buy a Ruger Waley(sp) Clapp 3" GP 100 without hesitation. I own a 4" GP100 and a 3" S&W Performance Center 686 Plus seven shot and while I would give the edge to the 686, you can buy two GP100s for the price assuming you could even find the...
Your low temp issue with Weaponshield may not have been the lube. I have had low temp problems with 22LR that were in fact slightly dirty chambers. The common wax lube used on 22LR gets pretty hard at low temps and a much smaller amount of fouling can cause trouble.
I have tested at least a dozen lubes/clps for corrosion protection over the past 10 years. My test method is more rigorous than most commercial methods. I thoroughly degrease a 1 1/4 wide mild steel bar and abrasive blast it "white". This removes mill scale and "activates" the surface (as...
I have two procedures for managing copper fouling.
1) Complete removal I use KG12. It will take all of the copper out including pits etc. I only do this when a barrel appears to be "distressed" or on an old milserp or similar.
2) For routine cleaning and frequency depends on the gun, I...
It takes more than a "little" sanding to make a AK mag work in a Saiga. There is the small matter of welding up the front of the AK mag since the stock Saiga does not have a bullet guide which if installed means you cannot use unmodified factory mags. Also it would have to be a 10 rd AK mag...
mnhntr:
I'll take +-2" hits with point blank aim out to 220yds any day for what I use a 223/5.56 for. Each to his own I guess.
I know I can get dead on at 300yds with an 8" hold over and 300yds is realistically about the limit for 223 bullet terminal performance.
You are correct re velocity. Quick Target shows 55gr BT starting at 2925 hits 1800 at about 380yds. At 230yds it is going about 2250. I confused expansion threshold (1800) with fragmentation threshold (2200-2300).
Quick Target also shows that a 25yd (23 meter) zero will peak at about 8"...
I can only comment on the AR with sight center line at about 2.5" above bore and in terms of defensive/hunting use:
For a 16" barrel rifle a 50 yd zero or about 2.5" high at 100yds will put shots +-2.5" POA from muzzle to about 220yds. It will shoot about 8-10" low at 300yds.
The best...
With respect to bimetal bullets and barrel wear:
Higher quality bimetal bullets may have a thicker layer of copper over the steel. Since copper is softer than the gilding metal jacket used on jacketed bullets a bimetal bullet with a copper layer that does not allow the steel to touch the...
The last time this issue was raised a rep from ATK said " XM193 ammo meets all specs for commercial ammo and is safe to use".
I sold all of my XM193 ammo and now I load my own. No more questions about what I am shooting. The Lake City brass is usually good. The milspec bullets are not very...
