Re: S&B variable scopes
The zenith is replacing the classic line, its new shape, apparently better coatings'than the classic(but i cant tell the difference) I'd choose a S&B over a Swarovski or Zeiss any day. there is nothing wrong with the classic line, the zeniths (although looking like a french wine bottle) have the superb flash dot in much of the range. excellent for moving targets.
The PMII's have 13mils or elevation in 1 turn, put that on a 20moa base and you have plenty of adjustment. get the double turn and you've even more( the varmint and ph scopes have limited elevation, your only good to 550 yards or so depending on caliber)
I can whole heartedly recomend S&B scopes.
The PMII tacticals are probably tougher, thicker tubes, mil spec etc, but that doesn't mean the hunting type scopes aren't tough, they are as tough or tougher than anything else out there.
and yes, the PMII 4-16x is available in a 42mm Obj.
