[QUOTE="Innovative, post: 1590289, member: 527"] For the 300 Win Mag I recommend using the bushing that is .003" smaller than the neck diameter from one of YOUR [U]loaded[/U] rounds. Be sure to measure this area if you ever switch to a different brand of brass; because neck thickness can vary (by several thousandths) when you switch to a different brand of brass, and then you will need to use a different size bushing or use a .305" neck mandrel. On a hard kicking caliber (like the 300 Win Mag) there is no need to crimp your cases when you use .003' neck tension. Don't under estimate recoil when using a muzzle brake, because most of them actually [U]increase[/U] recoil for your rifle - even though the shooter feels a great reduction of recoil. With less than .003" of neck tension (and a muzzle brake) you might find some of your bullets being pushed deeper into the case. This is caused when the direction of recoil is reversed by a muzzle brake. [/QUOTE]
