Frangible Ammo for .223 AR15

drvsafe,

There is also two types of frangible out there. The powdered sintered metal and copper bonded. FTF with frangible is a common situation unless you have excellent M-4 Feed Ramps on your rifle. If you get a chance to look at a Rock River CAR A4 or similar tactical rifle check out the ramps. If your rifle has the M-4 type feed ramps they can be polished with very fine polishing tips like the ones made by Cratex! I use the medium grade polishing tips. You do not want to remove metal just polish the ramps. Normally this will also for the biggest part eliminate the frontal bounce. The heavier grain frangible could assist with reliability. They have less front end bounce when going to the chamber up the feed ramps out of the magazine. Sometimes going to an H-2 Buffer will help? Slows things down a little bit.
There is also sometimes a problem with side strikes on the target at 50+ yards. This is all due to the barrel twist if you ever experience this. The sintered frangible in the 55 gr rangeseem to shoot best across the board in the AR.

 

What about the Hornady V-max range (or A-max or even Z-max for that matter).

Its normally great to feed in fussy rifles.

 

drvsafe and Remfire,

Frangible is a totally different type of ammunition. As stated it is comprised in this case of the sintered metal which is a powdered metal bullet bonded into a bullet. When it strikes anything hard like steel for instance it turns to powdered dust immediately. The other frangible is a copper powder bonded with a material like ceramic. When it strike a steel or hard target it also turns to dust. They are used in a lot of indoor ranges because they can sweep up the copper dust and sell it by the pound! For example using a frangible bullet I have stood with in three feet from a steel target and shot it. Not that I would recommend doing it! The bullet totally disintegrates on impact with not shrapnel! The bullets like the V-max and Ultra Max are of the regular ammunition family. They are regular bullets with a polymer center insert. And you would not dare shoot a metal or hard target at close range unless you want to get cut possibly or worse!
Hope that explains it a little more for you!

Genius!. Never heard of them until now, thanks.

 

frangibles tend to have very minimal charges to prevent the bullets from vaporizing soon as they leave the barrel. they arent long range rounds. open your gas block some if yours is adjustable. using a light weight buffer may help with cycling. just dont forget to switch back for regular ammo.

 

i would not polish the feed ramps that can easily and likely make it worse.

 

Maybe a dumb question, can you shoot hollowpoints or softpoints? They said no fmj, and frangible ammo is expensive.

 

Osha is making range workers were environmental suits to clean up lead and fining those without proper protection. That may be why they switched ammo on you. http://www.osha.gov/pls/oshaweb/owadisp.show_document?p_table=NEWS_RELEASES&p_id=22524

 

frang. 223

I'm in Florida and my local range buys their 223 from National Police Ammunition... out of Miami i think. I have a Colt 6920...1:7 twist and their 45g sintered product is solid out to almost 200 yards.

 

Looks like you got some keyholing going on. The one closest to the center of the x looks normal the rest look like there is some wobble happening
