Hey Fred,
J. D. Jones sent me a load that one of his friends uses in his T/C Encore ( 24" or 26" barrel, I don't know which ). He is using fire formed .375 JDJ brass, Federal 210-m primers, 55 grains of AA-2520 and the Nosler 260 grain .375 caliber accu-bond bullet. He is getting 2400 ft/sec with the 260 grain bullet. That should work on anything except elephant and rhino.
Sincerely,
Dave (Bubba) Thornblom
