I ran accross their web page and found that they make shotgun to pistol/rifle cartridge barrel inserts. And it got me thinking a pair of their 18" 45-70 inserts in a double barrel 12ga. could make for a "poor mans" double rifle. Any expierences or thoughts on such. I am looking at buying a SxS 410 in the next few months and am interested in the 22RF and 22 Hornet inserts.
