[QUOTE="budlight, post: 36016, member: 2939"] I just bought a twist rate program. it's not here yet. But the basic rule is for a given caliber the lighter the bullet the less barrel twist. So as the other person mentioned sub 200K is a wide standard used. When they first came out with Super explosive bullets for the small calibers they had to give a vel. limit. I had a 220 swift and bullets were not in one piece at 200 yard paper. They were hit with shrapnel. The thin copper skin and high velocity/spin rates made them come apart right out of the barrel when the core lead in theory get molten because of barrel friction. I do agree with the faster powder types uses in small bore guns the 26 inch is about perfect. I have used target guns in the 28 -30 inch range and speed increase is minimal do to the fact that the pressure wave is so down on the bell curve and the fact the bullet is already going so fast that it only spends sub 1/1000ths of a second in the last inches of the barrel [img]images/icons/shocked.gif[/img] [/QUOTE]
