Mark,

using the same charge with IMR 4350 and 140s, I get 2750 fps out of a standard Ruger factory 22 inch barrel...

moly'ed bullets and a little more barrel.. plus Hodgdon vs IMR 4350.. I could see another 100 fps...especially with bullet seating...

I know with each factory 260 I had, the first thing I did was have each one throated out to handle magazine length 142 Sierras and 160 grain Hornady RNs...

that allows shorter bullets to be seated further out...and gave me an increase in velocity..... ( I know you personally know all of that stuff... just putting it in for those that may not, and heading off any questions from the naythsayers)
