Finding pellets to suit the Retay T20 barrel

In this test I try out 12 different pellets in the Retay T20 to see what works best at 40 yards. Seven of the pellets were H&N brand and the rest were various brands. Unfortunately I didn’t have any JSB Heavy pellets or medium pellets to try, so these will need to be tested at a later date. I have also found that RWS Super-field and Super-dome also work well through the barrel in previous tests. New 3D printed magazines for the Retay, Pishtov, Pneuwa, Sovran rifles in .22 and .177:
