[QUOTE="MagnumManiac, post: 1391315, member: 10755"] Your twist rate of 1:10” is actually err’ing on the fast side, just as this twist rate is in the 300 magnums. Any 250gr will stabilise in your rifle with this twist rate. A 300gr will also be fine in this twist. BTW: Over-stabilisation is a myth! A bullet is either stable or unstable, there is no grey area regarding this. A bullet can be spun so fast that it is torn apart, but that is not the same as instability. It will be point on and not tumbling/yawing until bullet break-up. I have witnessed this ONCE. A 125gr TNT HP out of a 300WM @ 3600+fps was a blue/grey streak from about 15ft from the muzzle, the target had NO HOLES, not even shrapnel. Cheers. :D [/QUOTE]
