Oh, now you *are* talking see how many 3/4" barrels you can fit in a 3" tube, fill the space in between with epoxy at the breech end and then you'll have your marble shotgun without the extra weight, drag and hassle of a sabot

dont you mean 15mm? well in aussieland its 15mm that fits marbles right 3/4 (20mm) is too big)

and yea i will do!
