I once traded for a brick of that Eley the match shooters all love so much. It would not cycle ANY of my semi-autos!
It's taken me several years, but after extensive (and I do mean extensive) testing, I migrated to exclusively CCI standard velocity. Not because it was the most accurate, but because it was the best-shooting that met my three simple criteria:
1. Must function reliably in every .22 I own;
2. Must have reasonable accuracy;
3. Must cost no more than $0.10/round (this was pre-Obamascare)
I used to stock several different types of .22 ammo, not quite one for each gun, but nearly so. I finally got fed up with that, and began my quest. CCI SV was the grail. Not good enough to be the Holy Grail, just a garden-variety grail, but a grail nonetheless.
