On recoil... Not that I dont disbelieve the report of no recoil, but I know that my 7mm RM kicked pretty good shooting 160's at 3000 fps. Kind of hard to imagine an 280 AI not kicking shooting 162 A Max's @3140 fps.
Believe me I understand your concerns. Not to hijack the thread but that was the reading yeterday. The rifle is a savage long action. Rock cut barrel 8 twist at 28 in. The Rig sets in a Mac Stock. So I guess it is about 14 lbs with the NF 5.5-22X56. I had been running rl 22 @ 56.5 with really lack luster results. On a wild hair I switched to 17 and man am I happy. This rifle was built by Harrold Fred. My veolcity has been running from 3120 to about 3160 so I am in the process of switching to small rifle primers to tighten up the velocity spread. We shall see. Sorry for the hijack.
Forgot to answer you recoild question. 7mm Rem Mag and 280 AI both with the same velocity not even in the same catorgory in recoil. Someone will probably show some kind of chart that say they are the same but the felt recoil is way less in the 280 AI. I have both
One more edit. This is my 1st time with the powder. Used a 280 REm load went up 1 gr and started going up. The gun shoots pretty good @ 53. The Velocity is way better than I would have thought SO I will stay for awhile. Gonna work with primers and seating depth. Most likely I will stay with the 162 amax just cause they are cheap and I like them for deer and steel.
