Load for 22-250 with 1/8 Twist

[vonb]

I recently purchased a Tikka T3X in .22-250 with a 1/8 twist. I bought it due to the twist rate as I want to shoot heavies. I'm looking to shoot 75 AMAX through this 22.4" barrel.

What loads do you recommend? I have RL-15 and H4350 on hand. Also, what can I expect for velocity? I'll be using Lapua brass.

I get about 3150 fps with 80gr. SMK and H4350. Not really a hot load, and groups nicely at 300 yds.

That's out of a 28 in barrel though.

34.1gr H4350 80gr Amax and 80gr VLD

I shoot both 80gr SMK and 90gr SMK in my 8 twist. The 90 is short enough to completely stabilize and it shoots great. I use 36.5gr of RE-23 and get 3067fps. I could shoot faster but this load groups very well for me.

We are seeing 3050-3100 out of a 7.57 twist 26" Krieger barrel with the same powder.
