.375 H&H Ackley Magnum (40 degree)
Anyone have any data for a good load for this cartridge using Nosler 260 gr. partitions? I haven't found much on the sites I have visited.
Thanks all in advance

ramrod340I've only loaded for one years ago. It liked a full case of IMR 4350. I would look to the medium to medium slow burn rate.

Savage99I have one and could never find data that I trust. There is the book on wildcatts by Wolff but it's just a bunch of articles with each author going hot as can be to justify something.
I suggest that you work up from H&H data using a chrono and watching for pressure signs. Mine has freebore and will chamber the 375 Weatherby but I will not use that data either but just work up my own. Stuff like this gives me the creeps.
