I did some messing around in the reloading room this morning guys, found out some info at least I believe I did. I modified three fireformed cases by just neck sizing for enough tension to slide a bullet. Measured the three over all lengths of the rounds after verifying lands scratches and used a hornady bullet comparator for ogive measurements. Taking and average of the three, to my understanding if I seat berger 68 grain match targets off the ogive at 2.267 this puts me fairly close to bergers book coal of 2.71. most of the overall lengths averaged anywhere from 2.697 to 2.72 with the varying bullet tips. I haven't had any heavy bolt handle or pressure signs at this length so I'm going to continue this batch of 30 test rounds unloaded up. I've got five rounds each of 39,39.5,40,40.5,41, and 41.5 grain varget loaded to as precise measurements I can do with my equipment and experience. I have a few rounds that are varying three or four thousandths long on seating of the ogive, after I get those seated a little better I'm going to spend a day shooting. This time I am going to clean between every load of five and fowl barrel. Ill also allow barrell cool down for a half hour or so. I was thinking trying at 100 yards or should I try 200 yards? I'm confident that my ammo is as close to match as I can get, if this don't show accuracy then back to the drawing board.
