I'm just getting into 22lr competitions and recognize I'll have to test multiple brands and lots of 22 ammo. How many rounds of each type and lot do you shoot for groups? Do you clean between each type of ammo or other method (i.e. foul with x number of shots before shooting for groups)? Do you test at 50 yds or 100 yds? I'll be shooting PRS type competitions out to 200 yds. Any advice is greatly appreciated.
Any idea how Lapua or Eley do this process?
