I shoot the 75gr a-max bullet in my 1 in 9 ar. Never had a problem & I load them just off the lands/grooves for the best accuracy. They have to be fed into the rifle 1 shell at a time. Which is no big deal to me since I'm using them for the prone slowfire relay at 600yds in the service rifle shoots.

Just what kind of accuracy are you expecting to get out of your mini-14?
