I picked up my new RIA 22 TCM rifle on Monday. The 22 TCM round is a short 223 case loaded to the same length as a 45 ACP round. The 5" pistol gives 2000 FPS with a 40 gr. bullet and the 22.5" rifle gives the same round 2800 FPS. It's going to be a fun combo. It'll replace my 22 mag. rifle.
This is one sweet minie Mauser style rifle with a sweet no creep trigger and a 5 round magazine plus my 17 round magazine fits the rifle also. I have a nice Simmons 44 Mag 6x18 with Mil Dots scope to install. More scope than I need but it's handy.
And yes the magazine is loaded and one in the chamber. At present it lays in my nightstand and my Aug 223 with three 30 round mags. are close by plus a Mossberg Bullpup 12 ga. shotgun loaded with 00 buckshot.
I can reload the 22 TCM for less than 50% the cost of 22 mag ammo and pick a much better bullet design.
