With sane and similar pressures and barrel lengths about 150 fps day in and day out.

257 Wby with 26"= 3600
Anyone running either mucho more than that is running a tish bit in the red...grin

I have seen loads hitting 3700 often enough with a 26 inch barrel, my 27.5 inch barrel and Moly'ed bullets gets me to 3800 with safety margin to spare. I hit 4,000fps with trial loads but those WERE too hot, by quite a bit... Interestingly loads that hit 3900 did not show any of the mormal 'signs' of high pressure but I backed down to 3800 as I am reading more and more of how the old signs we used to count on being unreliable barometers. Figured 3800 was plenty fast enough and the cases last a long time at this speed. The deer think it is an awful load.
