I have recently aquired a Encore in 45-70 and am looking for a second chambering. There are so many more than there used to be. I considered the 6.5 BRM but brass is only made by eabco and no one else. I am thinking of 6.5 Swiss or 7-08 or 270. Something in that power range. Most important is accuracy. I would consider the 6PCC but it is really a bit too under powered and would require a custom chambering for Encore. Any suggestions?
