That's not a bad group. I don't reload for the .300WM so just been watching.

79 grains Reloader 22, Federal 215 M primer, 165 grain projectile. Hopefully you can find some. It's my go to recipe for my 300 WM. If not your H4831 sc has a similar burn rate so try the same load with it.

I have used that same load with decent results

Was this the best group or the worst? Doesnt look bad but could probably tighten up. Especially the vertical. Do you chronograph?

Every once in a while I’m not going to be shooting any more out of this rifle I have had a headache for two days and my eyebrow and shoulder hurts

The vanguard I had needed a good stock, I put it in a Hogue and It shot a lot better.
