I recently purchased a sendero II in 300 rum, and it doesn't want shoot at all!
I have tried three different Remington factory loads and the best group I can get at 100yrds is 3 or so inches. The rifle is less than a year old, and only had about 25 round down the pipe. Any suggestions or comments would be appreciated. I guess I'm wondering how other senderos shoot from the factory also.
You should definitely be getting better performance than that. Is it braked? If not, maybe the recoil is getting to you? Are you able to shoot other rifles more accurate than that? The only other suggestion I would have is to bed the recoil lug and start reloading your own ammo. With a 300 RUM, you are crazy not to reload anyway.
No the rifle does not have a brake, going to have GA precision install one soon.
I have a savage 308 with a brake that I can shoot ragged holes with all day long.
The rifle came with about three boxes of premium Remington amo with different power levels and bullet weights that I'm not impressed with. Does anybody have suggestions on loading data to start with?
