[QUOTE="scheme, post: 2450678, member: 117961"] I’ll add a couple of more points. Easy one first, Accurate/Ramshot sent me some .25-06 AI data when I emailed them. I’d be happy to forward that on to you, or I’m sure they would if you just asked. It’s limited, and for “traditional” bullets, but you can be confident in it as a starting place. Maybe I missed it, but what bullets do you intend to shoot? I’m not really tracking your post above. Standard or AI will have plenty of stuff for antelope. I mean, even if you were confident in 750+, with the [B]right bullet and powder combination[/B], either version will get it done. 100 or so more fps (which I actually believe is low for the difference in velocity between standard and AI, with the heavy bullets anyway) will just give you a little less drop and drift out that far… For a little reference, the load I’ve previously mentioned is holding 1900 fps (still above minimum velocity recommended by Berger for their elite hunters) and over 1000 ft-lbs at 1k yards. The standard case falls a little short of that, but it’s still plenty good for pronghorn at that distance. Is AI “worth it”?… I’m happy with my choice. My fireform load is a 120 grain sierra gameking (because I had a bunch on the shelf) at like 2900. It shoots tiny little groups, and will be great for all kinds of game at “typical” hunting distances. I’ll use those loads when the environment and game makes sense to, and I could be relatively happy shooting that rifle, with that standard-case load for the life of the gun, but that’s not why I built it. I built it to shoot the heavy bullets fast enough to go long when the environment and game makes sense to. A standard chamber rifle probably would have been just as good for me, because I’m personally not confident shooting game far enough where I have to worry about the difference in performance being the limiting factor.
