Can I ask for your wisdom please...
I have a Meopta ZD 3-12x50 w/ ballistic turrets which feature twin vertical scales- a) distance (in 25m intervals from 100-425m) based on .308 168gr and b) clicks (.5 MOA)- my preference is for the distance scale utilised alongside a range finder.
I would like to have the flexibility to use rounds between 110gr and 168gr- so...
a) I could potentially get turret dials made up for the other weights (question- anybody had any experience with Kenton Industries please?), or
b) before incurring more expense I wondered if anybody knew of a simple set of rules for correcting please
eg: on the standard 168gr based turret dial, if using 110gr- deduct 35% of the range
I appreciate there can be a world of difference between manufacturer loads/ranges, but I'm after some simple "rules of thumb" with which to start testing on the range please.
Thanks in advance- and apologies if this has already been a previous topic, I couldn't find one when I looked.
