I always stuck to the general rule that the bigger the cartridge and the lighter the rifle,the smaller the scope.

This generally ended up at about 4X on stuff like 338's and 375's.This,after watching enough variables chewed up on them.

Also the animals you shoot with them are the size of mini-vans with fur coats.On that stuff, variables have been of questionable value and the added reliability factor is worth its' weight in gold




The 280 Remington is overbore.

The 7 Rem Mag is over bore.
