Yeah,

Thats the idea... instead of wasting a 28" blank to make one barrel with 10-12 inches thrown away, buy a 32, 33" blank, doble chamber for 2 rifle-legal barrels.. Or with a <30" barrel have one legal rifle barrel and one pistol/SBR barrel..

Now I'm just trying to figure out who said they were doing it that way.... LOL Ultimately you save the cost of an additional blank..
