As a matter of fact I bought a heavy .22 cal barrel blank just for that purpose. My only concern is that I have heard that the 22s would tumble down the barrel of the Boys. I have a Kreiger match barrel on my rifle, and while it is by no means a sniper rifle, with it's original iron sights, I don't want to ruin it either.

I also picked up an old 50BMG barrel to chop up and make a similar sub cal device for the Bofors 40mm.
