22 LR cz457 barrels

[600-60x]

Looking at barrels for my 457
L31 has one with a wasp chamber ?
How are the wasp chamber demolitions different than the standard chamber

Apparently the Wasp chamber has a 1.5 deg leade angle.

The otherwise similar SAAMI Match chamber has a 5 deg angle.

I hear a few reports that some skilled gunsmiths have lapped CZ barrels, with a taper at the muzzle, with good results.

I hope there not being shot in sanctioned ARA factory class as that is not allowed. no lapping is allowed; this came from Dawn and Brandon.
Quote, only recrowning is allowed for work on the barrel.
