Ok, here's the deal. I'm loading a Boolit/load I can't find really any info on. Here are the specifics,
40 SW, 175gn SWC (40 cal version of H&G 68) drops at about 178 gns
Starting load is 4.0 gns Titegroup, oal 1.125, crimp measures .423 ( did find data for the crimp)
When setting these up I had a fairly narrow range of finished cartridges that would fit the case gauge, and an even narrower range that would pass the plunk test in my STI barrel. So I went with what I could. ( these Boolits are coated with Hi Tek lube btw, but that shouldn't matter.)
Took everything to the range, ran them through the chrono, recoil felt a bit heavier than usual, and started seeing some flattening of the primers, but I barely made 165 power factor.
I'm not sure what to do here, if I try to increase COL to reduce pressure, ( I might be able to go to 1.135), I will drop below major power factor.
Have you veterans got any ideas/ advice?
