50 at 100: CZ 455 Lothar Walther Barrel: SK FlatNose Match
As the title states, 50 shots at a single aimpoint at 100 yards.
Any rimfire rifle, or pistol, any caliber, any setup you like.
Not everyone has access to a 200 yard range, but most have access to a 100.
Let's see just how tight those clusters can be with ye'r favorite rig and the cartridge it "likes".
No rush, take ye'r time, use windflags and/or one piece rests.
