Thanx for the info so far. Sound like the 45-70 should not be any worst than the 375, and likely better. It is interesting that the heavy, by weight, loads sound to shoot better. I guess my follow up question would be, has anyone reloaded any semi-spitzer type bullets? If so any better results? Less drop, better groups, anything. I'm thinking Barnes Original, TSX or TTSX or Hornady Mono Flex or Flex Tip, etc?
