300 Win Mag Seating
Hey Man,
To be honest with you, I've shot a 300 Mag once, not a bad round. Anyway, to the point. When I was working up a recipe for my 30-06, I read somewhere that if the most accurate rounds that bench rest shooters can use are the ones where the bullet is seated approximately 5 thousanths of an inch from the begining of the lands. What I suggest is seating a bullet (dummy bullet with no powder or primer) extra long, try to chamber it in your rifle, if it doesn't work, give the die a half a turn then seat the bullet a little deeper. keep repeating this process until the round seats in the chamber and you can close the bolt easily. Over all length in reloading books are "a happy medium", meaning that because most rifles are mass produced. Thus by using the process that I gave you, you can find the COL for your respective rifle. Good luck and hope that this helps.
Jerry
