This is a sporter barrel.
Luck to you.....
That's why I would back off the powder load. Ideally I think 2650 would be idea. I wouldn't use 210M either, probably CCI LR200. I'm not trying to destroy my barrel or the rifle, that would be a nightmare.
As far as RL17 goes, I don't have a chrono, and I've heard it shoots a little hot. I'd rather stick to RL15 where I know 43 grains will put me in the 2650-2700 range.
