Laurie, what I meant is the F-Class shooter gets his sighters, can set the magnification that he thinks is right and make a correction. A hunter can't. Loosing a match is not as bad as loosing a deer or issues a sniper might have. yes I understand the competition aspect but also understand that the gear is in dynamic development and you might have a first focal plane target scope at some stage. They have some advantages. I personally have not measured or knowingly noticed any problems with my SFP scopes but also zero at max mag and shoot longer ranges at max mag with them. Prefer my ffp scopes for hunting.As is so often the case on forums, the OP and his question becomes totally forgotten. Would those rabitting on about what PRS competitors and snipers use please read the OP's post. He isn't a PRS competitor, or a sniper, or anything else. In a crisp 16-word post, he asks about long-range target shooting and F-Class at that.
As for variable scopes
only someone who doesn't compete in top level F-Class matches would say that. Sure, competitors tend to stick to one scope setting in a match but sometimes reducing light levels or mirage getting up make a change in power setting unavoidable. ....... and believe me, these people shooting into the very small small targets used in the discipline notice any change in POI that arises outside of wind changes. The philosopher's stone that everyone seeks is perfect elevation for 20 shots over a 30 or 40 minute match at 1,000-1,200 yards, every one 'on the mid-point waterline' and on some ranges in some conditions that exactly what people achieve in addition to sub half-MOA grouping.
How much does the centre dot or crosshair line on a typical sfp F-Class scope cover at 1000m nowadays?
