rifle in 1916, the .22 Rem Auto was never used in any other firearm. It will not chamber correctly in other .22 rimfire weapons, nor will other .22 rimfire ammunition, including the very dimensionally-similar .22 Winchester Automatic
, interchange with it. This feature was to prevent use of black powder rounds, which were still popular when it first appeared, from being used in the Model 16, resulting in powder residue rapidly clogging the action and rendering the weapon inoperable.

rimfire, and while it fires a heavier bullet, it offers no performance edge on either the .22 Long or the very much more common .22 Long Rifle
. It is not as accurate or as effective as the .22 LR, either.
