I did for several years.
It sucked.
Catch a stage at a bad time, early in the morning, looking into the sun coming through the trees, still foggy over in the treeline where the targets are. Can't see shit.
Guy comes through at 1pm and goes 1 for 1 on long range steel.
It might not be IDEAL with a scope and certain light conditions, but you can find the targets and make it happen.
As for batteries... illumination is overrated. I use it sometimes, but good glass and durability trumps all. Buy a Razor and enjoy.
People who say they can shoot just as accurately out to 300 yard with irons or a red dot as they can with a scope, are full of shit. Might be true on high contrast targets when the sun is high overhead and the target is clearly visible.
Make the target a grayed out piece of steel in the edge of a woods, in a shadow, at 5pm on the last stage of a major match, and it just might disappear without some decent magnification.
