75 Grain Amax in 22-250AI

[Skunce]

Anybody have any load advice for the 75 grain Amax? I'm planning to shoot it in a 1-8" 22-250AI. I've come across a few posts where guys say RL22 works well, but haven't seen anything about seatting depth. Anyone have an opinion about jumpping or jamming the bullets? Just looking for a little info to get me going in the right direction.

Thanks John

I seat mine to leave a slight mark on my bullet if I unchamber a round. Do not have a way to measure it other than this. I have good luck with RL22 powder or IMR 4350 powder. I tried them with a jump to the lands but the slight jam is more effective for me. 3300-3400 fps has worked best so far.

What charge weights are you using for those two powders?

[kslefty]

38.3gr of IMR4350 and 39.5 to 40gr of RL22, neither load seems to be a max charge but be careful with your own gun.

On my 22-250 ai 8 tw brux barrel i used rl 17 38.3 grs starting up to 41 grs max with the 75 gr amax with two nodes shooting 1 /2" at 200 yrds
38.6 and 40.2 with a col. of 2.585

Hey thanks RHH, I have a pound of RL17 sitting on the shelf that I had planned to use in a std. 22-250, but never got around to it. Do you have any velocity data on your loads? Are you shooting varmints with the 75gr Amax? I plan to use mine on rockchucks here in Central Washington.

on my old chony they showed about 3360 on the bottom and 3500 at the top but i dont feel those are accurate numbers i have since purchased a nother brand of chony which show about 200 fps slower on some different loads which i feel matches drop at different ranges better i plan to go back and compare some more
also the 75 amaxs i am useing are coated with ws2 so my pressures are lower than naked bullets
remember start low and watch for presher signs
