I just bought a old new FN-Mauser .264WinMag.BTW a nice classic stocked ,fast handling,rifle.What powders do you use in yours ? Which bullets work for you? thx

Hodgdon 870 is an old standby with 140 grain bullets. Start with about 70 grains.

I really like surplus WC 872, however. It is somewhat slower than h-870 and can really get the .264 moving.

H4831 and IMR 7828 will do for 120 grain bullets and below, but are really a bit too fast for best performance with 140's.

I haven't tried the new Hodgdon Retumbo or Viht. N170, but they should work also.

140 grain Nosler Partitions propelled by a compressed charge of WC 872 @ 3150 FPS is the only load I bother to use in my .264 these days.

73.0 grains of H-870 and the Sierra 140 HPBT bullet with Winchester brass and WLR primer. Sub 1" groups, 5-shots at 200-yards. Clocks around 3132 fps.

Thank you for the replies,loading data for the .264,unlike the 30.06 or the .338,is either old or lean.( except Steve's pages )Thank you Stonecreek,burn rates in a overbore,I guess, are quite important.The other problem is bullets,reliable expansion without blowing up,without breaking the bank.

For an accuracy load, go with 60 grains of IMR4831 and any 120-129 grain bullet. They all shoot .5" or less from my 264.
