So I see where PP2000MR has a stability factor of 0.6
That's my powder for both 9.3x62 as well as 404J.
I'm not really even a little concerned about my 404J load - at 2250 fps, even at 100° F, it's still a fairly low pressure load.
I'm not even overly concerned about the 9.3 loads, even though I'm pushing 286 gr A Frames at 2475 and 258 gr Hammers at a little over 2500. Ladder tests for both showed zero signs of pressure at the highest charge weight. I've got the COAL for both those bullets set well past SAAMI spec, with lots of freebore/leade still to spare.
I'm also not worried about modest velocity increases with warm ambient temps. I've done enough LD with heavy 45-70 bullets and all manner of .366 bullets to know any POI changes are meaningless at the sort of distances I'd use either of those.
My question is...should I be more concerned about the 9.3 loads than I am? I had no issues with those A Frame loads last week in northern Limpopo where afternoon temps were pretty consistently in the upper 80s to 90
