Re: 25-06 Ackley Imp or 280 Ackley Imp?
I was referring to a "standard" "factory" 25-06 cartridge not an AI and I think so was Marlow. I was shooting this gun (a custom heavy barrel on an enfield action, I believe)back in 1973 out in Missouri. The gun was traded away, and then in 1976 I got a second 25-06 and traded it away also. That is the trouble with being poor, you just can't afford to keep the good ones. I can go to my loading logs and pull out the loads I was shooting but they don't do any good for an AI. The little 75 grain bullet comes out of the barrel around 3700 fps in a standard 25-06 so I would expect you can get a hundred or so more fps out of the AI and this will cause a big SPLAT when it hits. If there is some ground hog size stuff to shoot in Alaska (or Australia) then one can have some fun.
