What do you all think of rechambering a Ballard No. 2 from (what appears to be) .44-40 to Ballard 44 Long or Ballard 44 Extra Long. Anyone have experience with either of these two cartridges? The rifle has strong rifling and is a late serial # with a forged receiver. Could be a good shooter/hunter. The .44-40 is too short to legally hunt in this part of the world.
