My wife got me a 11” 410 GNR barrel for Christmas. So I called today and picked up a set of dies and got the load data for it. I’m looking at starting with the Sierra 170 grain and Hornady 210 grain as I have quite a few of those from shooting 41 mag. What kind of velocities can I expect out of these bullets. Just sitting here day dreaming about my new toy!

in an 11" barrel in 410 GNR you should get well over 2100

fps with the 210 GNR and I would guess around 2250 fps with the 170 grain bullet. We got almost 2000 fps with a 6" revolver and with the longer barrel plus the absence of the barrel/cylinder gap you should do around 300 to 350 fps more. Every gun and every barrel is different so those velocities are a guesstimate.
