Re: Drop down turret or nikon rimfire bdc for 10//22 ?
Marty, don't know if you're still around on this one, but since most of the Nikon's come with a target turret anyway, i just apply reticle to it's furthest range then add MOA to it, i.e. if 300 yds. requires 50 MOA and i have a 20 MOA reticle then i just add 30 MOA and use the 20 MOA stadia point, whatever it may be.
With the 22 LR i really prefer a tree reticle system though as i find i'm always having to hold off for it.
