[QUOTE="ruby76, post: 1343410, member: 95995"] Thanks for the input guys, been doing some initial testing in a flurry before my moose trip this weeked. I started out trying to find my OL touching the lands. Other than calipers I do not yet have the proper tools for the job, especially to find the CBTO. Did the 'ol black marker test first, found what I though was the max OL and made sure I had room in my magazine. They barely fit so moved on. I then did a moderate load of 72 grains of H1000 and did the berger seating test (.010, .050, .090, .130 off). I reduced the OL by these amounts, I know, not ideal by any means. I'm using FC brass and Federal 215 primers. I only did one 3 shot group per, hoping to get lucky. Shot all the groups and they were all garbage, I'm using a bipod and rear bag at 100 yards. But, one of the rounds in the .010 group caused a stiff bolt lift and another had a faint ejector mark. Back to the drawing board I re-did the max OL test and figured the first time around I messed up and ended up seating all the rounds way too far off the lands. Yes, by this time my head is spinning around. Couple days later I loaded two sets of 3, at the 'new" OL (which is .015 closer to the lands than my previous closest of .010 off)with 71 and 72 grains Shot the first 3 with 71 grains, no ejector marks and the group was very good. Moved on to the 72 grain loads and shot the best group I've ever shot. Lucky maybe but I'm thinking the seating depth is much better now, just need to slowly work up the charge. One question I do have is on the FC (Federal) brass, is the capacity lower or is it quite soft? Quite surprised to see some light ejector marks at what I thought was a mild load and not jammed into the lands. [/QUOTE]
