300 WSM
Anyone have a good starting recipe for a 180gr for the 300 WSM?

Do you have any reloading manuals?
they all have starting loads for a lot of different powders. Have you picked out a powder?
Here is a link to Hodgdon. You can find about any reloading recipes here.

i have plenty of manuals, Hornady, Barnes, Sierra, Nosler, and i use the Hodgon & Nosler websites.

I was looking for a known accurate recipe that someone was using as a starting point

Play with caution: I mostly shoot 165gr sierra or nosler BT. I did try 180gr Hornady SST. They all shot good. I used H414 and Winchester primers for the 180gr, and IMR4350 for the 165gr. I started at mid range of the loading data and worked up to MY max load/… For the 165gr I started showing pressure signs sticky bolt at 62grs..
With the 180gr I had no pressure signs but accuracy was less than what I could settle for.
I try to load for a good accurate load @ MOA.
3 shot groups. Not much need to do 5 shot groups for a hunting rifle.
I did try a few other powders H4831SC, WW760 was close to the H414, MFG says its the same as H414..
I did get sooty necks at the lower powder weights with both powders.
I did try 165gr Grand slam they shot good MOA. I had one flyer unknown reason. I tried some 155gr sierra match and they shot really good.
Caution Is to start low and work up

Thank hivelosity, that was the kind of info I was looking for.
factory Hornady precision Hunter ELDX shot .525 MOA,
trying to get better than that, but we'll see.
