I have owned and tested quite a few rimfire sporting rifles. It would be impossible to list them all, or the loads that each preferred, but here are some examples of rifles and the load(s) that were used in each.

I have done quite a bit of rimfire load testing and most of these loads have done well in a number of rifles. I have listed the brand, type of bullet, and the velocity for all cartridges. The muzzle velocity (MV) for the loads listed below are taken from the manufacturer's ballistics tables.

Individual rifles will often give different (sometimes surprisingly different) velocities from the same load, so the figures quoted should be viewed as approximate. Note that it is usually necessary to re-zero a rifle when changing bullet weights or brands of factory ammunition.
