If you decide to own another powder look to RL25

One of the powders most often used in the .257 Wby is RL22. I can't remember my exact load, but I'm 1-2 grs below book max, and I believe I get around 3460 fps with 100 grs TSX bullets in a 25.5" barrel.

Use the search function for information on the .257 Wby, and you'll see an awful lot of RL 22 loads - some quite a bit faster than mine...

300winnie ---- I shot H-1000 until I discovered RL-22. I still use it for my target loads using 110grain Berger and 115 grain Nosler Ballistic Tip bullets. For my hunting bullet, which is Nosler Partition I use 68 grains of RL-22 and a Fed 215M primer. Do not start at 68, work you way up to that. That combo has killed about a dozen Deer per year for a while for my grandsons. Good luck and good shooting.
