I am reloading for a .308 ltr with lapua brass, 155 bergers, fed gm210's and 46.5 grains of varget. Now I know I'm close to max. Here's the issue about every other to every 2 rounds are hard to eject. The ones that are easy there is no extractor marks or any other pressure signs. The ones that are hard the entire case head is shiny, not just an extractor mark. there is also brass color on the bolt face. What's strange about this also is that I just bought the rifle new and it had alot of brass color on the bolt face right out of the box. Any ideas? I've checked my powder measure and the simple things. i have no blown primers or pierced primers. Very strange to me.
