just get a 20 degree base for your rifle it will work fine,if you like that 280 ai I would save that rifle to hunt with and just get a different rifle and what ever cartridge you decide on. but I would put a target Nightforce scope on it with a picatinny 20 degree base and rings,many use including myself a Nightforce 12-42x56 target scope with a target dot. good luck,Pete53
So you are suggesting not practicing with what you would hunt with or at the least a round thats identical in wind drift? That would be the worst advice I"ve ever seen on this forum I do believe.
By what some of us choose to shoot, competition wise, you can learn wind, but its not the best and not relative to your hunting rifle.
If I wanted to learn and wasn't interested in competition, I'd shoot my hunting rifle. Period. Learn it. Rebarrel it as often as needed.
Sometimes I think you should be savage53 not Pete 53
