Looking for a good load for the 7 weatherby with 140 to 160 grr bullets.

The reloading manuals are full of good loads for the 7mm Wetherby Magnum, it is not hard to load for.

Just stick with the slower burning powders like H 4831, RL 22, IMR 7828, RL 25, etc.

My own favorite load in my 7mm WBY Mag uses 72 grains of IMR 7828 and the 160 grain Nosler Partition. I live in California so I had to come up with a no lead bullet load. I switched to the 160 grain Barnes TSX and wound up using the same charge of 72 grains of IMR 7828. Both loads shoot great in my rifle and give around 3150 fps.
