I'd like to have a Guide Gun in 45-70 but probably won't any time soon. I do have a single shot 45-70 and .444 but want some follow-ups in case things get tight. My most likely dangerous game encounter requiring a heavy hitter would be an exceptional Black Bear with an attitude problem. Not likely but possible where I go. I don't bait bears here, but go into the cover where they eat berries. Question; have you used the old .35 Remington on the big boys and what worked best? I'm currently following Ranch Dog's program for this cartridge and gun (336). Been there done that? Thanks.
