In comparing my Diana 460 Magnum (23ish FPE) to my IZH 513M (6" cut off bbl)
(17 FPE) I'd say the Diana is a strong gentleman and the Russian is a strong
street thug

LOL Both are .22 and both have decent accuracy. The IZH feels
like it's producing 23 FPE and the Diana feels like it's producing less than
17 FPE.
The IZH actually produced about 20 FPE till I cut 6" off the bbl. Still I
prefer the rifle at 41" OAL over 46". The few fPE lose is no biggie to me.
Love to see Diana produce a Diana 460c Magnum (42" OAL) - that'd be great!
I'm sure it'd still deliver 20+ FPE in .22.
