I am looking into building a new 300 RUM.

My goal is to use the 181 Hammers.

I have a Montana Arms 300 Rum, but the bullets need to be seated so deep in the case, I loose allot of case capacity.

Ideally, I would like the seat the bullet with the top of the boat tail at the neck/shoulder junction.
Ends up being 3.850" OAL.

Who makes an action that will accommodate a loaded round up to 3.900"?

Currently, I am considering Kelby's Atlas, but I am open to other recomendations.
I built a 338 edge with a borden timberline action stainless. And it came with 3.850 mag. and the bottom metal. i bought directly from borden. I have used alot or most other actions. And borden ranks at the top of the pile. check them out it may be the way to go.

Nightforce has great tracking capabilities, they are rugged, a bunch of elevation, holds zero forever, and reticles are designed for long range shooting. So if you are looking to shoot long distances constantly, then you need a scope that can take the abuse. -- gilmillan1

Nightforce is such a solid combo of reticle, available elevation, glass that is good enough to shoot at the longest range you can dial. Nightforce has bullet proof construction that can handle the incidental horse rolling or some other rodeo action. -- bigngreen

The total package. Nightforce is the best I have used as far as turret feel and solid detents. I have never had one that didn't track right on and always return to zero. Nightforce NXS is the best value for everything I need. -- Broz
