RIPCZ barrel twist not as advertised?
Here is the table "RATES OF TWIST" from page 29 of the 2008 CZ catalog.
We have discovered that there are CZ rifles in 9.3x62mm chambering that have 1:14" twist rather than the advertised 1:9.5" twist.
CIP standard twist for 9.3x62 is 360mm or 14.17" .
Anybody else found any variations from this list of twists? Anyway, CZ has not held strictly to CIP specs on twist.
Note all the 1:10" big bores:

Duane WiebeI have Kreiger 9.3 barrels with 12 twist..For the 500 Jeff 1 in 20...I imagine it would take a life time to determine "best" twist...then change one small factor and all bets are off..I just tell Kreiger the intended catridge and they run it in their whiz-bang computer to determine twist...never disappointed!
