reminds me of this conversation I had with a clerk.
pretty sure he had a napolean complex..., telling me how the 12ga slug is bigger faster stronger etc..., lol.
basically I was saying the 20ga is faster/flatter, less kick, more accurate and plenty powerful at 200yds.
he of course preferred having "more power" and shooting further.
anyone shooting 200-300yds with a slug gun...is very questionable IMO.
and I've always found 12ga slugs to be less accurate than 20ga, but hey more power to you if you can accurately place a 12ga slug at 300yds.
IMO a 100-200yd slug gun shot is very far.
as to your topic, I'm a 1 gun, 1 bullet/load kind of guy, I don't want to be re-sighting my gun for every hunt, elk vs deer, vs antelope etc...
