I don't have any load data, but AA2495 is almost the same as the 4895s. So if you can find any 4895 data, you can substitute starting data and work up.

It's a lot closer to IMR4064 than it is to IMR4895, so if you find data for either, drop 10% and work your way up.

yes scooterf79, mine has a shilen select match barrel, 1:9, has been together for about a year now, have tried reloader 15, and varget in it, 27.5 grns. of varget, 75 A-max, cci 450, bullet seated to the lands, will put a 5 shot group into 2 inches at 300 yds. Have some 77 smk's coming, need to try them and some 2495, also want to try some imr 8208, just trying to do a little better

The Accurate Powder run rate chart shows it closest to H4895 with IMR 4895 just behind and IMR 4064 after that.

And the Hodgdon burn rate chart lists the following

87. H4895
89. IMR4895
92. AA2495
93. IMR4064

I know which one I'll choose to follow.

Thanks for the info marv,
Im putting a 6br together right now and the 22br will be following. Im looking forward to messing with it some. I would think some tinkering would get your groups down tighter than that.
