There were several different brads made, but you're going to have to scour the used gun inventories of gunshops or onine to find them.

The older Marlin 60's did, IIRC, and I know the Mossberg Models 50 & 151 did, as did the Winchester M-74 & M-190/290, the Savage Model 6, and the Remington models 24/241, 552 (as posted above) & 550.

I have also ran across several imports whose barrels were marked for all three .22's, from Italy, Spain and the Philippines.

It ain't no fun, when the rabbit's got the gun
