[QUOTE="nkyshooter, post: 2132906, member: 83787"] Remember that roughly half of the total elevation is available in the down direction as well (75/2=37 down) ... the rail moves you up ... yours is 40moa so you very well may not be able to zero at 100 and you'll probably be near the limit at 200yards ... You'll know when you take it out to zero it the first time ... if you run out of adjustment while zeroing, it will be in the down direction and you'll know how much you're off ... you can decide then to either change rails or zero at further distance. While it might sound counter-intuitive because it is typically NOT desirable to have more available in the scope in the down direction than in the up when zeroed, if you are 'lucky' your scope will be "off" a little bit and short you on the "upside" ... i.e. If you had 35 up and 40 down instead of 37.5/37.5 for your 75 total ... then your 40 moa base will let you zero at 200 no problem (maybe even at 100) and you'll have 75 total up available to you from there ...
