Erma .22 conversion for P 08; FIRING update post #21

[ithacaartist]

The SE 08/2, being the last model of kit made, apparently could handle high speed loads, the ones that are the next notch up from Standard Velocity on the list above. Early, mostly-zinc alloy .22's they made in the 60's were made before the higher velocity was so common, and might likely not have have been designed to use it. The later KGP 69, made mostly of steel, had notes included with the gun that recommended high velocity rounds. But there is a limit. When initially testing mine as I acquired them, finding the ammo each one liked best, I made the mistake of using Stingers by CCI. You could hear the difference when firing, and their excessive energy broke three separate cast Zamak front toggle links in mine. So, though the stinger rounds are .22lr, they are hyper-velocity ~1600 fps and should be avoided in semi-auto pistols if there is any doubt about whether they can handle this load.
