hello all, i started out with a diamond back ( dpms), ar-10 20-inch barrel and went to (dpms) 24-inch Brownell's barrel , i reloaded some Hornaday 135g a-tips at Sami specs and it jams into the face behind the feed ramps, the round goes Straight threw the feed ramps, so know im not sure what to do??? the Winchester 125 g open tip rds works fine, the Winchester 125 g extreme point jams up just like the 135 g a-tips do, are they just to long or is it the angle of the feed ramps?? here are some picks of were the rds are hitting and the are 2 pictures of old barrel with the wide gap at bottom and then 2 pictures of the new barrel , any help would be appreciated.
