Art Tuttle always insisted that the T20 was a better rile than the T44 that became the M14and could have been developed in half the time at half the cost. He was biased, of course, but he was there at the time. This is he firing the T20E2 on auto at Quabbin Reservoir, Springfield's test area... note three casings in the air and the muzzle is still level. Colorized by me.
