Ever since I saw my first 4 3/4" barrel a while ago, no other taper has ever taken its place as my favorite. Looks good to me, handles ok. The 550/450 taper (4 3/4") on a 30 bore does it for me every time. I have a picture somewhere of a guy's Navy Luger with a 7" taper like this............looks swell.......
I think a lighter barrel taper may help with any 22/30 Luger attempts, less mass to fuss with.
Lots of bullet mold outfits offer simallish 22 bullet wares, not like the old days, most ranges today will not allow lead bullets; but..........the molds are out there still.
I have done this taper on 4 3/4" thru 14" in real 30 Luger and the wildcats thereof.......always functioned ok. My scope mounted Luger mule has the longer barrel now with that taper. The 4 3/4 taper to some may not hold as steady as a heavier taper or bull type, but to others fits the bill ok. So kinda a choice thing........
I ventured into the spec of the 223 A.I. a little, it has about 1/2 the body taper of the regular 223, so cutting that off might have a slight advantage perhaps.
Trying find a sub slush fund now for a new reamer.........what's another reamer among the many...........it would do the bushing neck sizing die and forming dies..........and the 223 A.I. might do the body sizing............just dreaming this morning.
