There is no important difference between American 22 LR ammunition and European 22 LR ammunition except the most accurate 22 LR ammunition is all made in Europe these days.Īs to the actual ammunition diameters, the nominal maximum bullet diameter of 22 LR ammunition is. It is better to cut at the chamber end and rechamber such barrels. Because Anschutz barrels have bores that taper such that they get tighter toward the muzzle, it is important to never shorten an Anschutz barrel by cutting at the muzzle end. You may find the sources at:Ĭlick to expand.Many more accurate rifle barrels will have a slightly tighter bore or even a tapered bore. None of this information is secret - this is industry standard data and is published. To answer your specific question, the difference between CZ 22 WMR and CZ 22 LR groove diameters is a little over 0.004 in according to specificaiton. ~0.005 in smaller than SAAMI, and a minimum groove dia. However, for 22 LR, the CIP standard specifies a minimum bore dia. There are differences between the two specifications for 22 LR barrel dimensions.įollowing are the CIP minimum specifications for barrel dimensions:Īnd for comparison, here are the SAAMI minimum specifications for barrel dimensions:Īs you can see, the 22 WMR dimensions are common to both CIP and SAAMI standards.
Flylo is correct in that the 22 WMR and 22 LR use different groove (and bore) diameters, however the specific dimension provided is for domestically produced firearms - the CZ have a different dimension.ĬZ follow CIP (European) standards for manufacturing firearms, whereas US companies follow SAAMI/ANSI standards.
