I loaded a few with h4895 and 127 lrx and was getting a little over 2400 fps from a 22? 1-8 tube. I was hoping to hit 2500. Groups weren?t too great though.
Factory CZ barrel is 25.5 inchs and my load averages 2636 fps. Starline brass and cci450 primer. If you can't seat them at 2.300 are longer you probably can't reach this speed. And it's not safe for the ar.
