I don't know about the spec'ed bore size but I know DBs were never made in .22 WMR so in that respect, I don't think it would be .224". I'd be more inclined to believe the bore size was spec'ed for the .22 LR.

A while back on the Forum,someone brought up the "fact" that around 1970,or so, Colt had gone to a compromise bore refiling diameter size,as so many of the "Frontier Scout" size Colts were DUAL cylindered for the .22 lr. and .22 Magnum.
They said this was also used on a
ALL Colt. 22s after this date,of which the only non D'backs and "Frontier Scouts",were the few Mk.III Trooper .22 lrs. and .22 Magnums,I think.

Anyway,I've heard this before,that the bore size was larger than normal .222?

Blokey-- I remember the D/Bs ads listing the .22 Mag as an option, but I've never seen one.

Hart Rifle Barrels is near my home town and I know Jerry and the boys. Maybe I'll stop down and ask them to measure (air gauge)the bore. I'll report back if I do.

Thanks.
