this may be a well over posted and open question but.
What is the best .223 ammunition to use for an AR?
conditions;
Non-corrosive - prob 75% of ammo in Canada
commercial - again, prob 75-80%
great for target shooting - as in punching tight groups? what bullet weight do you want?
decent price - whats a "decent" price? $1 a round? 0.75,0.50,0.25? a round?
How did this happen? Pics?Ok, I'll revise my earlier comment. It may be hard to define best, but steel cased ammo is definitely NOT a front runner for good stuff to run through your rifle. Steel on steel is a great way to loosen up your chamber.
you should first determine the twist rate and OAL of your barrel, as this will be parmount in deciding grain weight of your projectile. if your using an AR with 1:9 twist, it will probably be best with a 55 grain whereas a 1:7 likes the heavier stuff.
You don't need pictures to know that two metals of equal hardness rubbing on each other will cause each other to abrade. This is one of the main reasons brass was chosen for cartridges. Brass doesn't scratch steel. Steel casings didn't really become popular until rifles with sloppy military chambers started making their way into civilian hands. Something that starts sloppy and loose isn't going to be noticeably worsened by steel cartridges. That said, most modern AR15s aren't known to be terribly sloppy to start with. No comment on Com-Bloc firearms though...How did this happen? Pics?
Just trying to figure out how mild steel lacquered, polymered or copper washed cases are making chambers looser and scratching them. I'm curious if you have proof of this.You don't need pictures to know that two metals of equal hardness rubbing on each other will cause each other to abrade.
