Re: Savage Build Questions
I presume you are talking about a 7mm Magnum.
Yes, it should accept the other calibers, but honestly, the 7mm is an outstanding LR accuracy cartridge.
Most companies will make a drop in barrel for you.
Benchmark barrels out of Washington State have a very good reputation (they don't have a website).
From 6mmBR:
Benchmark Barrels
Benchmark built its reputation with record-setting rimfire barrels, and now they are producing excellent centerfire barrels as well. Contact Ron Sinema or Barry Graber at (360) 652-2594 or email benchmarkbarrels[at]yahoo.com. No website yet. Location: Benchmark Barrels, 1105 Pioneer Highway East, Arlington, WA 98223.
Shilen also has started to offer Savage drop in barrels and does indeed offer a .338 edge barrel.
Good luck and keep us posted on the build.
Sharpshooter supply is an excellent resource for Savage stuff.
