I have just purchased a Weatherby 30-378 magnum, and I am searching for some recipes for reloading. If anyone has any good ones worked up and would be interested in sharing them, I would appreciate it.
Welcome to the forum. Congratulations on your new 30-378 Wby, a great long range hammer.
There are a few fellas who have some great loads and I am sure they will assist you shortly.
You can also do a search in the Reloading section and you should find what you are looking for.
A 200gr AccuBond and Retumbo is what I would start with. 106gr of Retumbo and Fed215M is what my rifle loves. Also RL25 or H1000 would be a good choice.
At one one I swore I'd never own a rifle that take more than 100gr of powder and that changed with a 30-378Wby. Two powders that I got to try was Retumbo and H-1000. I started with 107gr Retumbo and worked up to 113gr with 180gr bullet and max load was 3460fps I got almost 20fps more than that and that's the load I used shot great not as good as POP.
I wanted the rifle as a LR elk rifle as luck would have it I was walk in one morning and shot a bull about 50/60yds from me. I'd keep the rifle for another year or two never hunted with it again so sold it.
