the more stuff I shoot and the more I experiment with it's gun seems to be shooting a bit faster than publish data would reflect across the board..
an interesting note 40.5 of IMR 4895 which one would believe would be at least close to the velocity of H 4895 there's only shooting 2550 75 ft per second slower than the H version. but also interesting it would not cycle the action...


I did a bit of shooting this afternoon and here's what I found for comparison purposes:

Remington 700 XCR CT 20" barrel 308 Winchester
LC15 brass
CCI 200 primer
Hornady 168 bthp seated to 2.8" overall length
41.5 gr. H4895
2617 fps
