What do you guys mean by "premium slugs"? Can I have some types and brand names listed here? How would you consider the 3" brenneke magnum? One of the gunstop commandos said "Oh...you can't use that on a bear, you need this" and pointed to the copper solid slugs. Gun shop commandos....sigh, I once had one tell me that the FAL was much more accurate than the M14, and more reliable too.
In my opinion the 3" brenneke is the most powerful slug there is. Followed by the Winchester partion gold, which of course no one can afford, so brennekes it is.
