Do try 181 gr for 300 WM?Here is the latest data: 11-29-20
GLT -- the barrel is a stock rem 700 mountain from the 80's, so it's 1:10 twist@cohunt,
Sorry I overlooked your data.
We had some confusion for a few days when I lost editing privileges due to a glitch.
It's fixed now and your data is added.
Thanks for bringing it to my attention.

I have some coming. I am getting 2990 on a Federal 175 g Ascent. 62.8 g RL16. Steve @ Hammer, suggested I start at 63g and work up from there. I may need to go to a faster powder, but I am pleased with the accuracy and stability of RL16, so I will see if I can get much more speed from the 178 with this powder.Still looking for someone to try the 178 in a 300wsm, guess I'll just have to order some and let my smith play around with to see what we can achieve. Any guess on what the speed would be ?
My Brother from down under "Farleg" has just gotten his shipment of 30 cal 151 AH's and he went to work immediately,( Thinking outside of the box) here is his load data, this is pushing hard and he has done no temp test's yet so work up with caution, Nothing will carry that home

I'm almost going to guarantee that you'll need a powder faster than the 4350 burn rate. My money is on something in the Varget burn rate.I have some coming.

58 degrees on the first test 72 degrees on the secondBBean,
Did he happen to mention what temp the higher load was shot at? Obviously it's probably too hot
