Need Help with 30 378 Weatherby Load Data!

Trial and error is all part of the journey! Just remember to keep detailed notes on what loads you try. It’s like a science experiment, but with more smells and fewer lab coats!

Haha, love that comparison! On a serious note, does anyone have tips for troubleshooting issues like inconsistent velocities?

Has anyone tried using the Hodgdon reloading data for the 30-378 Weatherby? I found it really insightful for getting started on load development!

I have! Their data is pretty comprehensive. Just remember to start with the minimum charge and work your way up to avoid overpressure situations.

Testing loads for accuracy is vital. I suggest using a rest and shooting group sizes at various distances to see what performs best. How far do you typically shoot?

I usually shoot out to 300 yards. I’m hoping to find loads that stay consistent at that range.

Wind and temperature can really affect your shot! I like to keep a log of my conditions and corresponding results to help adjust loads accordingly.

Definitely! Having a consistent methodology is key, especially in varied conditions. Who here has experience with ladder tests for velocity?

I’ve done ladder tests! They help in finding the sweet spot. Just make sure your chrono is set up correctly.

Am I the only one who thinks barrel break-in can influence performance too? I’ve noticed fluctuations early on in load tests.

That’s an interesting thought, landerson. I wonder if it varies per rifle model or is more about the barrel quality itself?

Totally agree! I think experimenting with different types of loads also plays a role. It’s a mix of factors!
