<Qu�bec>Load for 375 wby mag
Everything was set. I fireform 375 H&H brass in my 375 wby. I got die for reload in 375 wby. I just buy a bran new reloading kit from RCBS. But i have no load data. The rifle was a win 70 pre 64.

I think the barnes#2 manual has the most data for this cartridge, If not using barnes bullets I would start 1 grain lower than listed MINIMUM! Good luck

John SI'm having one built and am looking for some loads too. A friend who shoots a 375 Ackley says that 4831 works very well with 270gr and 300gr bullets. I believe he suggested 85grs as a starting load.

dan belisle94 gr Rl 22 with Sierra 300 gr BT, col 3.64", Rem 9/1/2 M primer. 2751 fps, and good groups. There is the possibility of more powder in this load, but it was already a compressed load, so I didn't bother.
89 gr IMR 4350, rest of components the same.
I've gone up to 91 gr 4350, using data from the Wolfe wildcats book for a 375 improved, but once I chrono'ed the load I backed off. I was getting 2900 fps, which is 378 Wby territory. No pressure signs in this rifle, but it still made me nervous. - Dan
