[QUOTE="AZShooter, post: 2361571, member: 5219"] Cannot comment on experience with that length barrel except to say that heavy bullets will loose less velocity with a shorter barrel. Don't listen to anyone telling you to use a faster powder because you are shooting a shorter barrel. Use the same powders that the loading books say will yield the best velocities. I did load for a friend's 300 WSM Browning A-bolt stalker that had the BOSS. The barrel was shorter because of the BOSS but cannot swear to exact length. I am thinking it was 21" or 22". The pet load that was accurate and quite fast was 230 Berger with 61 gr of RL-17 velocity 2735 fps. OAL of case had to be short to fit and feed from the 2.8" mag box. The load flattened a cow elk at 300 yds. Should you try this load formula please work up to it as rifle performance varies. [/QUOTE]
