Shot 10 that I loaded up at 41.5gr H4350 with 147 ELD-M. I'd hoped to gain about 30-40 fps and not find pressure but that was not the case.
I do think that the rounds showing signs of pressure sat in the chamber longer, but for the minimal velocity gain over 41gr H4350 I'm just going to roll with 41gr and 2513fps and load up a few hundred.
On a side note I'm not sure what the deal with shot 5 is... 2728 with no pressure signs! I'm thinking chronograph error (magnetospeed sporter strapped to a supressor). I excluded that shot from my AVG/SD/ES (I also calc'd it excluding shot 6 but not sure how realistic that is). I know that shot 6 sat in the chamber while I looked at the case on 5 for pressure signs and shot 6 was the first case I saw an ejector mark on.
Cases in order 1-10 from top to bottom rows 4 & 5 (from the left). Cases showing pressure are row 5 (from left).
