The standards for most modern 9.3s is either 1-12" or 1-14"
Ruger did their 9.3s at 1-10"
I have a #1 and it's much more accurate than I thought it would be. It's one of my all time favorite hunting rifles.

CZ lists their 9.3s at 1-14"
Merekel shows theirs at 1-12"

My friend Johan in Mannheim tells me that his new Mauser is one turn in 1 turn in 28 CM. That's about 1-11" but not exact. I don't know if that info is accurate, but it probably is.
