I'm sure this question gets asked a lot but here it comes again. I want to do my first float hunt in September for moose/grizzly. My two choices of guns are a 45-70 guide gun and TC Encore in .35 Whelen. I know both will do the job but would the lever action be preferred over the single shot due to both quick follow up shots if needed and the possibility of an attacking bear? If the 45-70 is what I take I'm going to go with a hard cast bullet but what weight would you guys recommended? The .35 Whelen will be used with 225gr Nosler Partitions or Barnes Triple Shock. I'm thinking that most shots will be less than 150 yards and in most cases way under that so both guns will be adequate as far as range goes. Am I thinking on the right track or could I expect to need to take longer shots?
