My current fave is the 87 grain Speer pushed by 35.0 grains CFE-223. Not a hot load, approximately 40K CUP, but it registers 3000fps on the bean out of my 22" barreled Ruger #1, and delivers sub-MOA accuracy. Just what a .250-3000 is supposed to do. It is a load I worked up for my last M1899 (cunningly accurate, it was, with that load) because I have a mountain of those bullets, and a stupid amount of that powder left behind when I rid myself of the AR-15. Fortunately that powder turned out to work a treat in the .250 also. It works great with the Sierra 87 spitzers too, as well as the Nosler 100 Ballistic Tips (its Douglas barrel has a 1-10" twist, and even handles 117's pretty well too, but what's the point with bullets heavier than 87 grains anyway?). The big jug of Reloader-15 that was my previous go-to in years gone by has gotten about a 1/4" of dust on it now since I switched to CFE-223. (And it lives up to it's name: copper fouling is nil when it's used.)
