Starline case capacity?
I'm trying loads for a new setup, with new Starline brass. Available load data vs actual case capacity has me confused. First try was with some 123gr Lapua Scenar's and Leverevolution, ran out of space and into compressed territory way before max gas gun load, enough to cause some OAL springback and marks on the ogives. I said fine, i'll go to a lighter bullet with much less case intrusion. Next load is Sierra 105gr TVK's and StaBALL Match. For gas guns, Sierra load data is 32.0gr max @ 2.245'' COAL. Loaded at max mag length of 2.260'' and 30.5gr its already pretty damn full, slight compression on seating. How i am supposed to be able to stuff 1.5gr more powder in there?
These are new cases, they can't be THAT undersized right?
**Powder is measured on an Autotrickler V4, the charges are accurate**
