[QUOTE="MontanaRifleman, post: 860692, member: 11717"] What do you mean by "over stabilize"? The only thing I can think of to call over stabilized is when a bullet's RPM is so high that it doesn't nose over beyond the apex of its trajectory. Bullet manufacturers are usually conservative when it comes to recommending a twist rate. So if you are having accuracy problems with recommended twist rates, it's probably not the twist. Bench Rest competitors usually get the lowest twist rate bore they can stabilize a a particular bullet with so if your bullets are making round holes (stabilized) you should be able to shoot good groups with them provided the rifle is capable and it likes the load. Bergers twist calculator is a good one for most lead core bullets. Mono's being a lower specific gravity will need a tighter twist rate than same length lead core bullets. Bottom line is, if you are following manufacturer recommended twist rates you should be fine. [/QUOTE]
