Shot another group with 75gr H4895 the other day, meant to time 5 shots but forgot to plug the Mag. V-3 in for one of the shots.
75gr H4895
200 SST
Ambient 50*
Barrel temp-60*
3204-3196-3203-3195 Avg-3200fps
Only had time after work to get in 3 shots today before darkness.
75gr H4895
200 SST
Ambient 14-17*
Barrel temp-20*
3190-3185-3189 Avg-3188fps
Differential over a 40* temp swing 12fps. Definitely one of the best powders I have tested, right there with Rel 16 and IMR 7828SSC.

That is excellent shooting. I do not think I can use that load in my RB PacNor .40. Thanks for sharing.

Great info and shooting. Thanks. I've got a 40 in the works. Don't really have any data yet. Any ideas on the pressure #'s for your loads?

Dave - I have a 392/ 400 Pacnor ( 1 in 16 ) with LRMP. Looking for some powder guidance for 250 - 275 grain bullets. It seems like most of the data is for projectiles in the 200 gr range.Any help will be appreciated.
