Re: Vortex 6-24x50 pst good for Bench rest ?
You don't need or want a FFP scope for benchrest. You do want/need a lot of magnification and extremely clear glass.
NF rules the roost as far as the number of match winners using them, with March a close second. Most use the NF 12-42x56.
If you want a Sightron, head over to the classifieds at Accurateshooter.com, it's full of 'em. Vortex is popular with the tactical crowd, but I've never seen one at a BR match.
Another thing to think of is weight, some of these variable power scopes are between 2 and 3 pounds.
Many Factory or Hunter class BR shooters use the Leupold 36X or 45X to keep weight down.
