I'm looking at a 7x61 S&H, and find the ammo isn't all that easy to come by. So... I'm wondering... since the brass can be fire formed from 7mm Rem Mag, if it's possible to ream out the chamber to 7mm mag, rather than having to re-bbl. The 7x61 is a shorter case and a little greater degree of taper in the neck. If it isn't possible I'll probably go with a 264 Win Mag bbl. I have several 7 mag's already, but one more won't hurt.. Any thoughts??
