Spent the morning finding the best pellet for my Diana 48. You guessed it jsb 8.4. this is an older 48 with a t 01 trigger. Both 5 shot groups were shot at 25 yards. One under dime One dime-sized. Bag rested about 3 in from the trigger guard. This rifle was abused by the previous owner with the stock painted black with spray paint. I refinished it and put a nice leather sling on it. Relubed it and here you go! Fun times!
