Hello all. I'm new here and would like some advice because my rifle knowledge is not great. Especially regarding ballistics. I own an Over/Under rifle in 30-06 with iron sights that I plan to use on close range game like wild pig and close range shooting areas for deer, elk or moose. I'll use this rifle like one would use an iron sighted lever action rifle. I'd like a scoped rifle that would reach out to 500 yards (actually out to any range that iron sights would not work) -- especially for elk or moose. Would you recommend getting another 30-06 or jump up to 300wm or 338wm (of which I never thought of as a flat, longer range round, but I could be wrong)? Any insights? Thanks.
