6.5-300 Weatherby reloading info?

[Redbaron307]

Hey guys I’m trying to build some loads for a 6.5-300 weatherby and the info is pretty much non-existent. Does anyone have some load information? Thanks!

What a screamer - very cool.

I became curious about this cartridge after seeing your post and found this at accurate shooter:

Awesome thanks! That’s the most I’ve seen on anywhere. Hopefully it’s a shooter!

I just bought one. It’s fun.
Attached is a link to an article with some very good information. There are also a few pictures out of an old Sierra manual that are helpful. I ended up shooting 89 grains of H870 with a 124 Hammer Hunter.

PS I also have some factory ammo for sale if you are interested.

Hodgdon 2020 and 2021 manuals have some load data. A couple more loads online here: https://www.hodgdonreloading.com/hodgdon/hodgdon-h1000

My dad and i Both bought one and absolutely love it! killed a couple cow elk/1 bull and plenty of mule deer/antelope the last few years. When i bought mine in late 2018 i purchased a few boxs of factory ammo and the gun shot terribly, not sure why but 2-3 inch groups. Was able to come up with an awesome load that shoots sub moa out of both our rifles. I cant remember the load off hand here at work but its using 140gr Hornaday's with us869! Best part is that US869 is an available powder. You'll love the gun!!
