I typically use 57.0 grains of RL-15 with 250s as a starting point and go up from there. I've had several Whelen rifles and never had one that wouldn't safely use 59.0 grains of RL-15. My current Whelen reaches a bit over 2500 fps with 250s. Years ago Alliant listed 59.0 grains as a max load, I don't know why that's changed as I was getting similar velocity then too. I suppose anything that's had as tumultuous of a history as the Whelen has in wildcat form, it creates a tendency towards such downloaded data.
