you really need to let the gun tell you what it wants.
Very true. You may well be surprised.
Any time I had a new target gun...rifle or pistol....I bought as many types and brands of .22 ammo as I could afford. I sat down and shot those twenty shot strings.
In general, the more expensive ammo shot demonstrably better. The one exception was a High Standard Victor which really liked the old Federal 711s.
Federal gold medal match ammo proved to be a good choice for my guns.
