Hokay!
Got an answer for ya! Large barrels are 'alright' but aint up ta the quality we see today.
As a semi custom item its kinda like havin 'jourdache' on the pocket of yer pants.
I got two myself, one in .60, tha other .70, and a buddy in Columbus got three.
Yer better off with green mountain, BigIron or somethin new, and leave tha large barrel for a collecter.
