Colt New Frontier 22/22mag convertable? Anyone know what the correct measurement on these two are? My gun was brand new and Im just wondering if I should have these two checked .When I shoot 22 mag theres a huge flame shooting out the sides from where Im guessing is the cyl/bore gap.

Colt .22 revolvers of all types have a barrel-cylinder gap of a minimum of .003 to a max of .008.

The Forcing cone has a minimum forcing cone mouth of .238 and a max of .243.

Colt forcing cones are cut with a .160 taper per inch. This works out to about 9%.

NOTE: The actual taper of the cone is NOT critical, as long as it's not too steep or short. (Something I've never seen in a factory Colt).

The CRITICAL measurement on forcing cones is the outer mouth of the cone, and the only way to accurately measure is with a forcing cone gauge, available from Brownell's.

The .22 Magnum is deceptively HOT, and it's not unusual for flames to shoot out both sides of the cylinder.

Hey Thanks Defariswheel,your my kind of guy!! Love all the spec stuff!OK so Ill try and borrow a feeler guage and see what the gap is and alos measure the cylinder bores at the front to see what it is and how consistant they are. I wont worry on the cone.
