RE: I need info on the Hastings Slug Barrel
DD,
Never had a hastings barrel. Been looking at them for years. After reading here I might be convinced on buying one.
Hunt in shotgun only state(sucks) The cantilever barrel is a sweet set up and IMO the best method to mount scope on a shotgun. You get that gun set up with a sabot the barrel likes and you can take a deer out to 125-150yrds. That's a hek of a shot with a shotgun - but can be done cleanly with a good scope/sabot set up.
Come back and let us know how it shoots.
Good Luck
