 Hollow Points jam while ballistic tips feed 100%.

About 1 in 10 hollow points will jam in the feed ramp resulting in bullet set back. Standard ramps with perfect receiver fit. Tilting the tips up by inserting a wedge in the mag gap helps. Any other suggestions? Thanks, Leftyshooter.

M-4 extending the feed ramps will be the only real permanent solution over just cant wedging the mag in the well as a temporary solution.

Most of the AR rifle shops can extend the barrel extension/upper receiver to create the extended ramps to allow the Hp's to feed clean.

You might want to go to the industry forums here and post in AR-15 barrel's or ADCO (or could IM them) to get an idea of price and how fast would be the turn around time.

I have the same problem, just less often. We are talking 2%-4% of the time. I sent it back to Stag twice and they dremeled it the last time, not dramaticaly, but debured the edge and made a small ramp. The rifle still FTF's with Hollow Points. I am thinking about gettind a ramped barrel and ramped upper and swapping the rest of the parts over to see if that will fix it. Unfortunately that is about a $350-$400 fix. Any one with any suggestions aside from sending to a machine shop for work?

you might try polishing the ramps. get em smooth as glass. i've never had problems with a ar feeding, but that has helped on many pistols i've had problems with.

This would only work if the tip of the bullets are making it to the ramps. Best guess is if he checks his upper, there will dents just below the feed ramps where the tips of the HP' have been striking it (low feeds).

Try a new magazine and see if that helps , many times it can be that simple . I made 100 loads uing a sierra hollow point (full copper all the way up ) and I had no malfunstions . I had the problem you have with some lead tip bullets and found that the magazine was not all that . I switched to a different mag and the problem was reduced dramaticly . Lead tipped Winchesters are soft lead compaired to sierra and fedal . Lead tips in general can cause a hang up on the feed ramp .

Hope that helps a bit , Eric

The plastic on the Ballistic Tips is a pretthy hard and SMOOTH surface, where the hollow points do have a brevace that can catch on a "Burred Feed Ramp". That being said, your weapon should digest both.

The tips above are good ones. Make sure there are no burrs in the feed ramps and if there are, CAREFULLY and SLOWLY polish them out with a dremmel tool and jewelers rouge.

By the way, I do this to all of my .45ACP feed ramps as well unitl they are mirror bright.. Just makes me feel better!

I'll tell you what works for me, and you can use as much, or as little of the info as you see fit.

I've shot literally THOUSANDS of Speer hollow points out of my AR's. with very little difficulty. If you're using 30 round mags, try to pickup some old USGI straight bodied mags with the alloy follower. Then load an "uneven" amount of cartridges in the mag. I usually load 13, 15, or 17 depending on what the box / carton I'm loading from holds. The only reason for the 3 different amounts is I try to make all the loaded mags come out on an uneven number, and close to the same number of rounds in each. Like on a box of 50 it would be three mags @ 13, and one @ 11.

All my AR's are standard rifle ramps, no M4. They just seem to like feeding from the left side of the mag (uneven number) if you're looking at it from the top. Now keep in mind all these mags are OLD. All the bodies look fine to me, and I could probably avoid going this route if I were to put some good CS springs in them. AFAIK, they all have the original springs. But as long as this method works, I'll just keep on keepin on.

The only other rounds I shoot are SP's of various manufacturers, and no problems there either. One can never really have too many mags, so if you don't have any of the old straight 20's with the alloy follower, it might be worthwhile to pickup 2-3 and try it.

I'm not a fan of the NHMTG straight bodied 20 rounders, I have a few, and they don't work nearly as well as the old USGI, plus they're a very tight fit in all my lowers, so I wouldn't count on this method working with those mags.

The obligatory YMMV goes here. Hope this helps
