Does anybody have experience with the Barnes .375 255 grn F/N and AA-1680 powder. I'm looking for a good charge to start with for working up a load with this bullet.
Just try Conley.They have already loaded ammo for the 375Win.Here are some other hot loads I use in my Ruger #3,Savage M99A,Marlin M375 and Win M94 XTR.Expect a 50fps + loss in Win and Marlin,and be careful with spitzer bullets.Also the Ruger and Savage allow you to go over COL of 2.56,without getting in the rifling.In heavier bullets(spitzers) powder must be reduced to clear COL for Win and Marlin.
