I'd be more than happy to discuss the work you'd like done. I'd recommend the 7WSM with the 180 Bergers. I do quite a bit of work on Savages and can get you all the components you'd need and install them. For barrel recommendations I really like Brux barrels. They've got a good turn around time and their quality of barrel is superb. I have Brux barrels on a few of my personal guns as well as chamber several customers guns with them and they have all been great shooters. As far as muzzle brakes
if you'll be doing any prone shooting I'd go with a timed brake with ports at 3 and 9 o'clock so you don't get dirt blown all over you and your rifle. For timed brakes I install the Muscle Brake. It's the best quality brake from machining to performance. If your shooting off the bench you could go with a radial brake like a Vais. For the chamber I have a excellent PTG 7WSM reamer with .320 neck and no throat. I then custom throat to match a supplied dummy round. All you'd need to do is seat the 180 Berger to where you'd like it and I match the throat in the chamber to your dummy round you sent. If you'd like to discuss more about the build please feel free to give me a call or shoot me an e-mail.
