I'm reviewing new ammo for my 338 win mag, the old ammo it was dialed in for is no longer available, and I came across this in a review of a certain ammo:
"In my very fickle SAKO 338 Win Mag this ammo gives me 3/4" groups at 100m when I sort each cartridge for run out. The ones with the smallest run out I use for hunting between 0.03" to 0.06". The ones above this, some up to 0.12", I use for practice and to verify my zero."
Can someone tell me what "cartridge run out" is?
