Ken Waters included the .257 Improved in his Pet Loads series. He used the RCBS 28 degree shoulder version but that's close enough for my needs. If you don't have a copy of Pet Loads around, lemme know and I'll see if I can scan and send you that page.

Leftoverdj, No I dont have a copy of pet loads so if you could send me that page I would sure appreciate it. Meanwhile I'll keep my eyes open for a copy of the Nosler#5

Thanks

Sorry for the late response to your load request, but here it is. I'm loading 100grain Nosler bal Tip over 50.0 Grains of RL 19 Winchester +P Brass & Federal 210 Primer. This load gives me a velocity of 2645 from a 15 3/4" barrel. It has turned in several 1" 5 shot groups at 100 Yards. OAL is 2.850 This load is over listed Max's in load manuals. Start Lower & work up to it. It doesn't show Pressure in my barrel. Good luck
