Re: Barrel length and velocity?
I shoot a custom 6mm rem. It has a 1:8 twist medium varmit barrel,26 inch. if i could have put a heavier barrel on it i would have, but i was limited by the stock. I think If I was to start from scratch. I would go with a heavier barrel, but leave it at 24". just not burning that much powder, plus faster powders are better in the 6.5x47
