Just got my hands on a Marlin guide gun in 45/70. I was planning on using the Hornady LEVERevolution ammo w/ 325 gr. bullet. My shots will be 50/60 yards max. I will be hunting a cedar swamp.
Any one have any other suggestions?
I think that will work. I also think that Remington 405gr. factory loads would work, and the 300gr. factory loads made by Federal, Remington, and Winchester would work fine. I think the Black Hills Cowboy load with a 405gr. cast bullet at 1250fps would work fine. Certainly any of the Buffalo Bore loads would work.
60 yards isn't that long of a shot and black bears aren't armor plated. I think about any .45-70 load would work well.
