I load for 3 weatherbys, 2 are short throated, but you may find better accuracy by ditching the Fed215s and the 7828 for Fed210Ms and H4831sc, and you ES should be lower as well.

Thanks backwoods83. This is a different approach so I'll add it to my load testing. Always read that 215M was the primer to use for WBY loads.

For all powders that work good in the 300wby including Retumbo up to 90 grns Fed.210Ms or CCI BR2s work the best, imo you should never need any primer hotter than a CCI 250 unless its below 0 outside, Fed215s are very erratic, about 2700* or more.

190 grn VLD behind 80 grins of H4831sc and a CCI mag primer. It's on the light side however highly accurate in my 27 inch Shilen tube. Also loaded the 180 grn Sirracos with success.

Hey I have some CCI 250's and some H4831 so I am going to put some new loads together. Also load some 7828 SSC with the CCI primers. Erratic is what I am seeing with my current loads so am excited to see how the new primers will work. More to follow.... Thanks for the info!

Let us know how it turns out. Mine is a little frustrating as it shoots the lite loads like a house of fire, more in the 300 Win Mag range, but I cant argue with the accuracy.

Re: Any LR reload info for Wby 300 mag?

My 3oo bee took a bit of work to figure out. At the end of the day my go to load now is

180grn TXS
84grn H4831sc
Fed 215
RP brass
COAL 3.562"
3150 ft/sec

It's a .3moa load out of my Mark V UL. 26". I have given this load to a few other Mark V shooters with similar results.

But I do have to say the best move I made for accuracy in my rifle was removing the pressure point. Made a huge difference!
