Problems with Plastic Tip rounds in AR's

**leroy** · 10-28-2009, 05:14 PM

Dear fellow TGO'er:________
Finally got our AR carbine together, handloaded some ammo and took it to the range the other day. Loaded up several mags and started shooting. Everything worked just fine (about 8 or 10 rounds -- 20 round P-Mag) until i had a round fail to chamber. We took everything down and discovered that the round had evidently "stubbed" on either the feed ramp or magazine causing the ballistic "nose" to bend. That evidently caused the round to fail to chamber fully. The bent nose evidently hung on the front of the chamber and wouldnt let the bolt come far enough forward to close and lock. The question is: Have any of you all had similar problems with the balistic tip rounds? I was using nosler 55 grain ballistic tips loaded from 2.200 to 2.250. I suspect the "short rounds" may have caused the problem.

What do you all think?
Thanks in advance,
Kind regards,
LEROY

Overall length has alot to do with it. Check your load books and adjust. I always load 5-10 of a new bullet type/powdercharge and adjust accordingly.

Thanks for the post. I SUSPECT that the problem may well be the round being a bit short (2.20) vs (2.250), that may have caused the hiccup. I loaded the first batch "short" by not paying enough attention when i set up the seating die.

Thanks again for taking the time to tihink about this.
Kind regards,

We have 3 ARs and I have loaded everything from 40gr VMaxs to 60gr Noslers with no issues. Bear this in mind: Even a PMag is subject to being "out of spec". I've gone to Bushmaster mags on all of my rifles and have virtually eliminated any feeding issues. Lots of my friends shoot literally 1,000s of rounds every year and have found Bushmaster to be the most reliable mags.
