I thought I would see if the new LRX 200 .308 bullets would fly from my HS-Precision hunting rifle... Wow, I was pleasantly surprised. I was limited by the magazines OAL of 2.90. I loaded them so they fit cleanly. R 17 powder, CCI LRM, Winchester brass. 64.2 gr of R17 2.82 COL average velocity of 10 shot string 2990 (high 3009, low 2979) 1:10 twist 26" bbl 9# rifle. They should be a good elk hunting round.
