22 Long rifle and wmr in a revolver. Are they compatible in a revolver?

Absolutely not, unless you have a Ruger Single Six with interchangeable cylinders.

A 22lr in a 22wmr cylinder yes, but a 22wmr in a 22lr, no, it will not fit.

No way can this be recommended. A .22LR in a magnum cylinder has a good chance of rupturing.

Although the bullet diameters are the same, the larger .22 WMR chamber does not support the smaller .22 LR cartridge. Firing the smaller .22 LR round in a .22 WMR chamber results in swollen or split cartridge cases, high-pressure gas leakage from the rear of the chamber, and bullets striking the chamber throat out of alignment, which can result in injury to the shooter or bystander and which does result in poor ammunition performance.
