If I would have known it was going to be hard to get normal velocity, I would have gone with the 7mm-08. I was hoping for 2900-3000 fps. I've noticed on other tikkas I had trouble getting decent velocity also. It may be a tikka thing. The barrel is 24" and I planned on re barreling to the same caliber in a 26-27" barrel after this one goes south. I do sell guns a lot, but I'm hoping to keep this tikka and build off it. I don't think the 7mm STW will fit in the tikka action, but I've thought of going with a 7mm-375 Ruger when it's time to rebarrel. I think going with a longer tube will end up giving me the velocity I was looking for. I might have to try 4350. I didn't initially because I know it seems optimized for the 30-06 case.
