Re: barrel length 7mm wsm
You will see some reduction in velocity with a shorter barrel, maybe 40-60 fps. I have read that shorter barrels are more accurate, not sure if I buy that or not. My 7 SAUM has a 28" barrel and I wouldn't have a shorter one for anything. I'm burning less powder and getting higher velocities than any of the manuals say I should have. Barrel length is a personal choice that can only be made by you. I like longer barrels, many like shorter barrels. Longer ones can be a pain to find a quality case that's long enough.
