To all you 264 gurus out there. I need the Hogdon data for H870 in the 264WM with a 140 GN. bullet. My load books are to new to have this powder. Thanks for your time
Remember that rifles vary, so your maximum sustainable load may differ from some loading manual. The maximum with this powder and 140 grain bullets usually comes between 70 and 74 grains. An old Speer manual went up to 77 grains, but that would take a very "relaxed" chamber. It depends on the throating as many .264's were made with essentially no throat at all. You can typically safely achieve around 3100 fps from a 24" barrel and sometimes approach 3200 fps from a 26 inch barrel using H870.

Thanks for the info. I can't find H870 but the powder I want to use instead is WC872. Everywhere that I have read says to use 870 data, even the website I'm buying it from says that. Max load doesn't bother me as I work up all my loads from the start for each gun. I'm by no means as expirienced at reloading like many people on this forum but I'm not a noob. When the rifle and powder get here i'll be ready to go. Thanks for the help guys.
WC872 is great powder cheap and works well. I have used it in 300wby and my 50bmg. The burn rate of my WC872 is little slower than 870. So work up slow and have fun

I ran up on another question. Why does all of the reloading data I can find list a winchester large rifle primer and not a magnum primer? Any thoughts.

That's a good question for which I have no answer. I'd choose a magnum primer anyway, and for two good reasons: it's a large case filled to capacity with a slow burning rate powder, and because those powders generally have heavy deterrent coatings making them harder to ignite.

Let's say what we mean. It makes a lot of difference. WC-872 is, at least in the lots I have used, a great deal slower than H-870. You may wish to start with a "MAXIMUM" listed load for H870 when using WC872, but you'll be working upward for a while before you get there.
With MY lot (and lots of surplus powder DO vary), I use 80 to 82 grains of WC872 with a 140 grain bullet: 3150 in a 24" bbl and 3240 in a 26" bbl. But that is MY powder in MY guns. Approach such charges and velocities cautiously.
