Sporter factory Tikka contour

As in the Tikka 'Sporter', sort of a varmint contour or a slimmer sporter barrel? I hope my question makes sense.

Sporter factory Tikka 22-250 is about .630" at the muzzle, at least that's what mine measures.

It is the Tikka factory sporter barrel. I bought it as new take off. It shoots 1/2" at 200 with the 75 elements bullets and RL15.

I just put this barrel on yesterday. I have 75gr eldm bullets, what powder do you recommend? I ran h4350 at 35gr and was only at 2950 fps. I have some loads from 39 to 41.5 of rl26 loaded up to test. Curious what everyone is having success with. I am hoping to get to 3300+ . Barrel is factory length 22.4".
