Well just picked up a hornady bullet comparator, I'll seat bullets a little more accurately. Found out my caliper was messed up, bought a new rcbs dial and my measurements were all over. My original test loads resulted in just over moa at 200 yards, we will see if loading fireformed brass and seating off the ogive will tighten some groups up. I don't know if I will have enough bullet to find the lands with the 68 grain berger but I'll get a hornady oal gauge and make sure. Guess if it touches the lands with enough bullet in the case I'll have to adjust loads completely while keeping my magazine in mind. Since I'm a fairly new reloader, I was amazed how much of a difference in length there is in a box of 68 grain berger match. Anyone have any tips on modifying a fireformed piece of brass to find the oal of the chamber. Should I use my die or saw the neck on a case?
