I am looking for a 2000-2100 fps. loading for the Saeco 245 gr. bullet in my ,358 Winchesters. Ive already had good success with H4350, and 3031. However,4320 is listed in several sources as one of the best jacketed bullet powders, and Ihave an accurate load for the 250 gr. Hornady with this propellant. But I'm not finding any data anywhere for cast, I suppose I could use j word starting loads and go from there. Also, I have14 lbs of this powder and it will take a loooong time to use it up in my.250 Savage!
Wondering if anyone has used this propellant with cast boolits, and what results you got.
