Found a pellet that works. I found these old English Pellets in a box with a early 1950s Hy-score pistol. Milbro Caledonia 22 waisted slugs. Below I compared them to a RWS Hobby on left and and round ball on right. As you can see, it is slightly shorter, nice round tip and pretty stout tail. I loaded three pellets that I oiled, cause these were really old. I got three shots with no hang up and 2 shots were in the 200+ fps. So I was getting a better seal than with the balls. I look at the loading gate and it is much wider than the round balls. This makes me think the pistol was not necessarily designed for just round balls. But it was designed for older slug type pellets of its time. Question is are these still available? I have three left. Lol
