A friend has a Guide Gun in 45/70, is a non-reloader and would like advice on ammunition for close range Grizzly hunting in the Yukon. I suggested he look at Buffalo Bore cartridges. What do you folks think and also if it is Buffalo Bore which cartridge?

I love Buffalo Bore's 45 Colt Loads but use Garrett's 45/70
