Kodiak, that's great news! Experienced guide and a closer range will remedy lots of things! Since he's likely to be closer to the AND he is thinking about BJ's .270-160gr partition recipe, things sound like they are looking favorable. Non-bench rest practicing will still be key though.

Regarding the 12 gauge with slugs one hurdle to consider is some states have caliber and energy restrictions for high power rifle season, so don't forget to check the regs in the state he's headed to. Otherwise have him run it by the outfitter. Good job!
