I have used 9 but since my only 45 Colt I have left is a Ruger Montado on the small 357 frame I've been using 8.5. I haven't chronographed it but I would be real surprised if it wasn't running somewhere between 850-900 fps with the common barrel length guns. The Montado is 3 3/4" so I'm not sure how much it affects it but it's a lot less than it wolud affect a smaller caliber like 357.
