I'm loading .308, 150 grain Spitzer ballistic tip nosler bullets for a Savage FP10 bolt action with 1/9" twist, 24" heavy barrel.....I was reading somewhere that you could seat a bullet real long (no powder or primer) and then close the bolt on it and then it would seat the bullet to the depth of the rifling lands....and then to seat your bullets .015 to.030 deeper....the sierra loading manual says c.o.l. for this round should be 2.770"..when I tried this procedeure the c.o.l. was 2.926..this seems awful long to me..do any of you experienced riflemen have any advice for me on this?..would'nt that change chamber pressures?..I have been reloading pistol for about 3 years but I am just beginning to load Rifle rounds so I want to get the best possible accuracy from my rifle.
Any help would be greatly appreciated..
Thanks
