I also have a 6.5-20 Leupold on my 22-250 Stealth. Shoots pretty good with 37 gr of Varget and 55 gr Ballistic Tips @ 3700 fps.

The only thing I don't like is that it doesn't feed too well with a full magazine. Unless I work the bolt fast, the first two shots often don't feed; instead they pop straight up and get crossed up in front of the bolt.

Never trust a bow under 40 (inches).
