personally I have always used SFP MOA and it’s always served me well. And still think it’s a great system, however i always tend to get myself in a bit of a pickle when trying to range find or more importantly try to work out the size of something, granted more down to having unmatched turrets/reticule on lower end scopes .

Over the years I have been playing with FFP MRAD scopes and seem to get on sooo much better , I have put it down to the fact of every day I’m working in mm/ meters so I think im just wired up in metric. ( yes I know MRAD is not metric in the same way MOA is not imperial, but they both correspond well to each system)

anyway I have just taken the plunge and bought Two vortex 5x25x50 PST gen 2 scopes in FFP and with MRAD turrets and reticules , one for the tic tac .308 and the other for the other tic tac 6.5 creedmoor.

 so like I said what and why do you use ,
