Sierra bthp seating
I have a simple question (I hope). I am pretty picky on my reloads.
I reload a lot of 175 gr. Sierra BTHP for my .308 rifle. The OAL for my load is the normal 2.800".
However, after seating the bullet my OAL varies to some degree. For example, I seat one that measures spot on at 2.800". The next may be 2.805". The most is 2.808" probably. After measuring the overall length of several bullets, I quickly discovered that the Sierra bullets are not all the same exact length. I realize the ogive is what counts really.
My question is this. Since the die uses the ogive to press down on the bullet into the brass, should I even worry about slight variations in the OAL? The die should be pushing on the ogive, which is hopefully the exact same spot on every bullet right? So just because one loaded round is slightly longer than another, it doesnt mean the ogive is any different.
Any clarification on this would be appreciated.
