Hi gentlemen,
When working up your loads when do you typically call a given charge your maximum charge? When:
- Sticky bolt lift
- Ejector marks begin to show
- Cratered or flattened primers
- Other
Or is it a combination of all 3? The reason I ask is because I am working up a load for my 6.5x47 Lapua using Varget, CCI 450 primers and 130 gn Berger VLD's, and around 37 grains the bolt begins to get a little harder to lift, but I see no other signs. I tested all the way to 37.7 grains and still have no flattened primers or ejector marks, but the bolt is still a little tough to lift, although I don't need to karate chop it by any means. I want to squeeze everything I can out of the round, but want to do it safely of course.
Any feedback is appreciated.
Nick
