375 FL, Mag, 24 inch barrel. 270 grain bullet COL 3.69 I want to see what loads I can develop with 3031, 4064, and 4320, and get about 2400 fps with a 270 bullet. thanks | |||

Which 270? Since they vary in length the net capacity will differ Also case capacity a fired non resized case if you have it. 270 Hornady as Example Cartridge : .375 Fl. Mag. N.E.

If you're so inclined, give RL-15 a try. Gives good velocity and shoots tiny little groups in my 375 H&H with Barnes 270 Gr. TSX bullets. My do all African load. Anythng from an Impala to a Cape Buffalo with this load. Send me a PM if you want load specifics. Tom Z NRA Life Member | |||

Max pressure on the 375FL is about 15000 psi less than the 375 H&H As usual just my $.02 Paul K | |||

| One of Us |
I can't use H&H data in a 375 Flanged; too much pressure. I can't use Barnes bullets; cost too much and I have hundreds of Hornadys,, and I will never go to Africa anyway. ($). I do have lots of RL15 though, and I like that too. Thanks anyway. | |||

Yep RL15 is one step faster than 4320 per most charts I believe. As usual just my $.02 Paul K | |||
