So, I just placed an order for a .22 WMR carbine for the Mrs. Thankfully, it is already threaded. Which can should be used on said? A 9㎜ or 5.56㎜ one? The former will be lighter, the latter closer to bore diameter. Decisions, decisions.
This turned out not to be the case; they make some of that model that does both, but not all. Not going to risk it.Doh, I just googled it, and our .22LR can is rated for .22 WMR, so that is a third option.
Not sure I follow. At the present, the 9㎜ does duty on a .32 ACP SBR and .38 Special lever-action. The 5.56㎜ on an AR-15 SBR and standard Mini-14. So they can be swapped about.Do you have another "host" (threaded barreled 9mm or 5.56) that the can can be swapped over to?
Ie: you have no threaded 9mm, but you do have a "spare" threaded 5.56. Why get one that fits a 9mm, but no threaded 9mm barrel?
If you have both, flip a coin.
