Mikey,
My heavy barrel has been best shooting slug gun I ever owned, hands down. BTW - I also put a Sims recoil pad on it but the weight of barrel really help tame it down. Then again, I am over 6'4" and 255 so I have a lot of mass to slow it down even off bench. Bore doesn't sludge up with plastic either so either. I do periodically swab it out with JB's which really makes it slick. I have to wonder if barrel was on consignment due to something a bit amiss in cantilever. Anyway, I really like the heavy but will tell you it is a load to still hunt with. Great for off hand with barrel weight forward. I just tell myself no different than 54 Hawkins...
