Thanks for any replies
2900 is probably a pretty good guess. Using the data provided, QuickLoad says 2973 fps but I've not compared QL predictions with chronograph results for this particular cartridge and powder. It's usually within 50 fps with H4350 in my .30-06 and .243 so it probably isn't far off. With that in mind, 2900 fps to 2950 fps looks like a reasonable estimate.
