I'm in the process of helping my girlfriend pick out a deer rifle. We've been looking at the A-bolt Medallions. I would like to get her a .243, but the problem is that she is left handed, and I don't see where they made a .243 in LH, only .243 WSSM in LH. I did see where they do have a .270 in LH with BOSS. My question is with the BOSS would this keep the recoil down on the .270 to where it's close to that of a .243? I know the BOSS is designed for other reasons other than recoil, but recoil is the main issue right now. Thanks for the help.
