2011年2月22日 · All copper bullets penetrate very well, due to the length (copper being lighter than lead) and holding together. The Barnes X design expands with four pettals, which are triangluar with the leading edge in contact with the target upon opening being sharp which cuts through the tissue rather than crushing through as a standard lead core, copper ...

2020年11月11日 · I read an interesting article about copper bullets and weights compared to lead. It was an older article and I can't Find it anymore. Basically it stated that if you use non lead bullets you can drop the weight of the bullet for similar performance because they retain 90-100% of their weight upon impact vs lead bullets that retain 50-70% of ...

2021年10月29日 · Conversely my Winchester Bolt action rifle with a 24 inch barrel groups great with copper coated 22 LR CCI and poorly with RN lead Federals. OK, CCIs for my rifle and Lead RN for the Single six is how I roll today. All I can figure is the lead RN expands to fit the barrel better than the copper rounds, hence more accurate.

2019年3月7日 · All copper bullets often have a longer bearing surface and much more engraving forces that will often increase pressures thus reducing max load and speed-- this is 1 reason that driving bands are added, to reduce the pressures and copper fouling. But not all monolithic bullets are created equal, while both barnes copper, nosler e-tip.

2017年11月29日 · As for copper plated vs. lead bullets for .22 rimfire ammo, the "copper" coating is actually a copper wash and it is very thin. It is hardly a jacket in the traditional sense. The cartridges utilized by .22 rimfire weapons have an externally lubricated, heeled bullet. The bare lead bullets use a wax type lube.

2014年6月7日 · I have been shooting both copper plated and lead bullets in my 10-22 for over 25 years and no problem with either one. My most accurate bullet turned out to be Winchester T-22 which is a lead bullet. 5 shots at 50 yards into 1/2 inch, but I replaced the factory barrel with a bull barrel with "Bentz" chamber to get those groups.

2021年9月23日 · The monolithic bullets benefit from higher velocities in a given cartridge for ideal expansion. I normally use 140 gr bullets in my 7mm08, but I'm starting out with Barnes TTSX 120 gr .284 bullets for non-lead load development. For the .44 Magnum, I typically use 240-270 gr jacketed bullets, but obtained 200 gr .429 bullets for load development.

2012年9月23日 · In a .22 the copper clad generally work much better in auto loaders than lead bullets. The .22 CCI AR Tactical bullet works really good in .22 auto loaders that may have had trouble with other loads. Lead .22s seem much more …

2021年11月3日 · These types of bullets were originally made to fill a simple role and purpose. That being a lead-free bullet, but still be able to expand. States such as California have banned lead in hunting bullets for claimed environmental reasons. Thus came about the solid copper bullets, out of necessity. Necessity is the mother of all invention, after all.

2019年9月22日 · Yup. Lead core bullets are denser, if you use shotguns much, think of lead shot vs steel, lead shot carries energy better and hits harder than the same size steel, and even if you get pellets with similar weight, such as lead bb's vs steel T's, the smaller diameter heavier lead shot will still hit harder and penetrate better than steel.
