[QUOTE="Mike Matteson, post: 2177989, member: 101791"] I shoot a 220 Swift 1-14 twist, and use IMR 4064 for ever. Velocity at 3900fps, 55gr Sierra. If you step up a twist or two, then you can use heavier bullets if that what you want. That will slow down the velocity of 55grs bullet according to Sierra. I kept my velocity below 4000 fps to slow down the burn out of the barrel. It's been shorten once, and rechamber. [/QUOTE]
