THE 224 PLUMMER IS BASED ON THE 224 TTH WHICH IS A 22/6MM. THE 224 PLUMMER IS THEN IMPROVED TO MY UNDERSTANDING. THE 224 TTH IS CAPABLE OF PUSHING THE 55 GRAIN BULLETS IN EXCESS OF 4100 FPS. THANK YOU FOR YOUR INPUT.

I HAVE READ ON SOME PREVIOS POSTS ABOUT THE 224 PLUMMER SHOOTING SOME AMAZING VELOCITIES(4500 FPS WITH 55 GRAIN BULLETS I BELIEVE IS WHAT WAS STATED) IS THIS REALISTIC OR JUST SOME SMOKE BEING BLOWED UP THE POOP SHUTE? I WAS THINKING ABOUT GETTING A 224 TTH BUILT AND TO MY UNDERSTANDING THE ONLY DIFFERENCE IS THE PLUMMER IS INPROVED. ANY INFO CONCERNING THE TWO WILL BE GREATLY APPRECIATED. BY THE WAY, FIST TIME MEMBER LONG TIME READER.
