Am planning several hunts in future years for elk, moose, black bear, wildebeest, impala or similar, and possibly Cape Buffalo (this one is questionble)and need rifle recommendations. My current rifle is 6.5x55 caliber which is probably too small for moose and Cape Buffalo. Prefer caliber big enough without too much kick, flat shooting, not to expensive, legal, etc. .45-70, .375 H&H, .416 Rigby, or others to be considered. Understand that the recommended caliber may not fit everything. May end up selling this rifle once goal has been achieved.
