bullet 100 gr Speer BTSP #1408
cartridge .25-06 ack imp
cartridge length is 3.180
barrel length 26"
case capacity in h20 72.4
powder h4831sc
charge weight is 58.0 gr

I hear the program is pretty accurate but 269fps seems a bit extreme what data am I putting in wrong?
Changing from one brass manufacturer to another can lead to a large discrepancy in velocity. With one of my 308 rifles I see a difference of well over 100 fps between Win brass and RP brass. So your results may be due to choice of brass (or size of your chamber if you're fireforming your AI from regular 25-06 brass).
