BudsGunShop.com - 22 lr

The .22 LR and .22 WMR are not interchangeable, we should get that out of the way immediately.
They have different dimensions for length, rim diameter, and even bullet diameter (although this comes down to one-thousandth of an inch). You cannot take .22 WMR and use them in a rifle made for .22 Long Rifle, and vice versa. You might be able to get a round to chamber in the incorrect firearm but it’s not a great idea to pull the trigger.

Wayne, no Sir. 22 Winchester Magnum Rimfire and 22 LR are two different dimension cartridges and are NOT interchangeable to fire in the same firearm. This is precisely the reason two cylinders are provided in firearm combo setups such as here : budsgunshop.com/product_info.php/products_id/131242/heritage+manufacturing+mfg+rr22mb4bhbprl+rough+rider+22+lr22+wmr+6rd+475+cocobolo+bird+head+grip

no the 22wmr has a larger diameter case than the 22lr. the 22lr cases could split and cause safety issues in the 22WMR chamber

No, 22lr and 22wmr are not the same.

NO, this will only shoot 22 WMR and NOT 22 LR. You might have primer damage if you shoot 22lr through it. I hope this helps!
