So many ammo options out there. I was carrying a 44mag for back up while hunting but will be carrying 10mm (when I get it) from now on , I’m still researching the double stacks so I’m not sure what I’ll end up with. And I’d occasionally carry depending on where I’m going. I already mentioned it I think? I’m into carrying the same rd and mags for carbine and handgun (not deer hunting but maybe?)so my options are getting slim. As far as “how big of game would I shoot?” Depends on if I’ve emptied my rifle. If by chance I ever see a grizzly and only have a 10mm hand gun.... I’ll be wishing I had a 460 while dumping 30 or more rds of 10mm into the big fella haha
