If you say the Army never used .22 caliber trainers who did? If you concider the Mossbergs,Winchesters,Remingtons,Stevens, and H&R there was almost 100,000 .22 caliber rifles bought during WW11. The Navy, Marines and Air Force did not use all of them. Where is your infromation stating the Army used almost no .22 caliber trainers. I collect .22 caliber US Trainers and would find this infromation usefull.
