Are you going to go "heavy" on your build? Heavy Barrel, muzzle brake etc resulting in a heavy rifle? Are you going to hunt extensively ( carry) with it?

In the first instance I would go with the 300 winny, in the 2nd, Id go with the 7 Rem in a #3 contour barrel, no brake.

The 7 is a mild shooting rifle, accurate, plenty of info out there for reloading, as well as great factory ammo. Eveything that has stood in fron of mine has died.

Both are excellent cartridges.

Re: 300 winmag vs 7mm mag

In a custom chambering I would choose a smith who knows what his 7 mag reamer will do, I have a 7 mag that will push the 180 bergers 3050 fps. If the smith doesnt have his reamer dialed or cant achieve these velocities or buying a factory gun then I say 300 win mag.

I am intetested in what you mean by this. ( I am not well nomenclated in chambering, I thought a reamer was a reamer)

Re: 300 winmag vs 7mm mag

I chose to build my rifle in 7 SAUM a couple years ago, and have never regretted it. It's very accurate with the 180 Hybrid or 162 Amax and hand loads. I'm pushing the 180 Hybrid 3045 fps, which gives excellent long range results. I know you said you are inexperienced at hand loading, but with a small investment of quality hand loading gear, you will be amazed at what you can do. Besides, who wants to shoot a factory rifle with factory ammo? Good luch with your selection and pratice as much as you can, no matter which way you go.

A reamer can be a factory chambering but still have a few differences, such as bullet seating. I know my smith said he went through a few reamer designs before he got what he wanted. I know I seat my bullets long so thats part of it. Some people told me there was no way I would get 180 bergers to 3050 out of my 7 mag but I've confirmed the drops out to 1072 and it is. I'm not a smith so Im not sure how to explain all the little things you can do to get everything out of the chambering, maybe someone else could do a better job. I know that my factory 7 mag was only getting 2900 with 168 bergers before I gave it to my smith and had it completely redone. So thats why I say factory or smith without a tricked up 7 mag reamer I would go 300 win mag, the factory 7 mag just didnt do it for me.

Re: 300 winmag vs 7mm mag

I recently went through this dilemma and went with a 7 RM shooting 180 Bergers over the 300 WM. I have a 7 WSM, 300 WSM and 338 Lapua for the heavy stuff.

+1000000 on a good smith knowing his tools and what the hell he's doing makes for a fun shooting rifle
