Geemonites!!! Is it needed? It's a hunting rifle. A factory made hunting rifle at that! Oh, and it's 338 Winnn Mag. So I'm not shooting at an animal 1000 yrds or further out! Maybe 600-800 yards later on down the road, but certainly not now!
If I buy good dies and good ammo components wouldn't that give me "acceptable" runout?
So then I shouldn't worry about buying a stupid gauge right?
Or would it make my groups tighter at closer ranges? Hence the justification of needing one.
