Makes sense.

That is why I started with standard velocity .22 LR, then Eley rifle target; neither of which worked. The Peters high speed did.

What's the muzzle velocity of the Peters?

One can see from reading the post above that standard and high speed actually can overlap a little, so even the brand and maybe the lot will make a difference.

I think the speed ratings are pretty nominal; the only clear line is the 1100 fps, below which rounds are sub-sonic, by definition.

Your results will likely vary, but it is not at all unusual to have to select .22 LR ammo that functions well or better in any particular pistol- not just model- but individual pistols can vary significantly.

The same is true for other caliber pistols.

You said a mouthful there! Before the ammo panic, I picked up several boxes each of just about anything I could find in 40 gr RN, up to about the velocity rating of CCI Mini Mags, so I could offer this selection to each of my .22 Ermas. Some like a load a little hot, some do not.
