The usual disclaimer applies these are my findings yours may be different use my data at your own risk.

After a conversation with the manufacturer I used their formula of remaining case capacity after priming and seating bullet as max load volume then subtract 30% this is the starting load.

I started with a 200 gr lead round nose and 1.4 gr trail boss and worked up to 1.9 gr trail boss for a max load there was room for 2 gr but I didn't want to press my luck.......here is a table of my results using 10 rounds at each increment.

1.4 gr avg 394 fps stddev 18.38 high 411 low 366 spread 45
1.5 gr avg 411.33 stddev 13.22 high 432 low 395 spread 37
1.6 gr avg 433.67 stddev 11.72 high 457 low 425 spread 32
1.7....no data user error
1.8 gr avg 464.17 stddev 18.93 high 490 low 441 spread 49
1.9 gr avg 480.93 stddev 11.39 high 493 low 467 spread 26.....most accurate

given said results 96 wont cut power factor for any category in IDPA except BUG but good luck with passing an enfield revolver in a bug category. However it was nice shooting and comfortable.
