Need help choosing a caliber

OK, I thought I had my mind made up on a 7mmSTW with a 30" barrel. But more and more people tell me that I will have to re-barrel at about 1,000 rounds. I'm working with a model 700 action with a 8mm mag bolt face. Not wanting to really change the bolt face. i'm looking for a nice smooth custom build. I will be punching paper and using for anything from groundhogs up. I have another 8mm mag so don't need a large caliber. Just looking for a caliber that will shoot flat and decent speed. but not trash a barrel. What are my options?

Re: Need help choosing a caliber

Most calibres with a mag bolt face are going to burn out a barrel. You could go down to 7mm rem mag ad get a couple of hundred rounds extra, or go to 338 edge.
How many rounds do you expect to shoot each year? How long will it take you to shoot 1000 rounds?

Might take me 2-3 years to shoot that many rounds. I have been thinking of doing a 338 edge also. Wasn't sure If I could use the donor action I have?

A 338 edge is a magnum bolt face, should be no problems. Maybe get an extended magazine box. The feed rails may need to be opened as the Edge is a fatter cartridge.

Thanks for the info. I think in the long run the edge would be a better choice. Will be placing a order on the barrel soon.

Re: Need help choosing a caliber

You said groundhogs and up? Up to what? If it is up to deer size why not build a 6mm Norma BR.? It is one of the most accurate rounds out to 1,000 yds. I built one for hunting and it has shot 2 5 shot groups at 200 yds in the low .3s" and almost all the other groups were under 1/2". May get 10,000 rounds out of it before you need a new barrel. I killed an 8 pt. buck with it at 200 yds and had a complete pass through the neck spine and out through the leg bone on the other side.

If you don't need such a big bore rifle get one you will really have fun with.

PS: I'm going to hunt antelope & mule deer with it this fall in Wyoming.
