Buy a box of as many types of ammo as you can find.
Fire 12 rounds from a benchrest, at 25 yards, into a real target. This will tell you volumes about what your revolver prefers.
I have a Model 17 made in the early 1990s. It shoots best with:
Federal Classic 40 gr. solid
Federal Gold Medal 40 gr. solid.
Both put 12 rounds into a circle 2 inches in diameter.
CCI High Velocity Blazer was all over the target, giving 4 inch groups at best.
More than any other caliber, .22 rimfires are persnickety, whether they are handguns or rifles.
What works for your revoler may not work in another's revolver. You just have to try a variety and see what works best.
Write the brand and make on each target, after you've fired 12 rounds, and keep those targets. It will refresh your memory for years, and become an invaluable reference.
Don't forget to put your gun's make, model and serial number on each target. If you later buy an identical model, the serial number will keep things straight.
