I am wanting to have a rifle built and strongly leaning towards .280AI. I want to shoot primarily 150 or so grain bullets for deer, sheep and the occasional elk. I want a barrel no longer than 24", no muzzle brake, and a lightweight rifle, like sub- 7lb. I am thinking I'll have Shawn build it for me, if he's not too busy to get it done before hunting season. How will the recoil compare to .300 WinMag? What other cartridge should I consider that is in the same neighborhood? This is going to be a rifle that I just grab and go for deer hunting mostly, but I still would like to be lethal at 700 yds. It'll probably end up getting packed around on mules and horses a good bit. Can I fireform factory .280 stuff by shooting it, or do I have to start with Ackley Improved brass? I don't know which is best. Oh, and no need to welcome me, I am Troutslayer but I had to re-register because the forum was not letting me retrieve my password. Set up the way I'm talking about is .280 AI going to be pleasant to shoot, or will it kick too much?
