[QUOTE="Mike Matteson, post: 2350245, member: 101791"] From my Sierra Manual 1971 I load for my 220 swift 1-14 twist 24" barrel. IMR 4064 powder is what I use, Fed 210 primer. Grains are from 35.3grs to 39grs. Stated velocity is from 3500fps to 3900fps. In the newest manuals they show different. I believe that comes from faster twist rates barrel to shoot heaver bullets. The 55grs is all that I shoot from my swift. Other manuals I feel that they have slowed down the swift to show that their rifles are better. It bug the hell out of me. I know better. That's why I don't ever throw out my older manuals. I do purchase new manual all the time to stay up on new chambers and there loading. I use this 39grs in summers @ 100+ degrees without any problems. [/QUOTE]
