don't forget Mossberg. Hastings barrels are nice, and they are MADE to shoot the Hastings Laser Accurate slugs. Consequently, they shoot the remmy buck hammers, lightfields and Hastings slugs about equally. the Hastings are the cheapest of the lot.
My mossberg barrel (yes...they make factory mossberg barrels for the 870) likes the hastings and lightfields too. I've never shot the buck hammers that i can remember. Every barrel will favor a specific bullet/shell combination and you still need to shoot a few of them to find one you like.
Personally, i like my parkerized mossberg barrel. it's very trouble free, and it took a coat of camo paint quite nicely. Seeing as how my slug barrel is deer only, i'm going to work some blaze orange into the camo pattern for it on the barrel only...but that's a whole 'nuther thread LOL
