With 12x scopes, I'd say 1/2"KZ should be the lower limit...October 11 2010 at 8:35 AM

Response to Revisiting target sizes for pistol FT
and that's for a 10-12 yd range.
IMO, 3/8" is too small for PFT, at least with at 12x scope... sure you could 'get lucky' and hit it sometimes, but that's just it, you'll need 'luck'.
I'd say that once you start pushing the envelope, for example:
1) KZ's smaller than 1/2"
2) scope mag higher than 12x
3) power above 12fpe
You're basically favoring "rifle-FT-like" rigs... and what's the point? (We already have a 'rifle-FT' game!).
