Chrono results! Two TC Omegas. One blued one stainless, with similar round counts. Same loads. 45 cal 250 gr XTP in Harvester crush ribs over 70 grains Swiss 3f Holy Black lit with Winchester 209 primers.
The blued gave 1640 fps with 11 fps hi/ low variations.
Stainless 1695 fps with 9 fps variations hi/lo.
The bores were swabbed between shots with rubbing alcohol.
Now 55 fps isn't a lot, but it is something. I think it a good comparison, using same make and model rifle and same loads.
My 24 inch stainless Firehawk beat my 26 inch ( blued) Black Diamond XR by 40 fps with this same load. Seems to confirm my thought that all things being equal, stainless gives ( slightly) higher velocities.
Ymmv.
