24 or 26 inch barrel, what rifle.
"I" do not like any pressure signs on my load. It appears you are concerned about pressure; otherwise, you would not post it here. If you are concerned, take it down a notch to a much safer zone. You have the ultimate choice to proceed with what you have and people's recommendations, but you are also responsible for your safety. There is no substitute for safety - SAFETY, SAFETY, SAFETY ...Now to the question, I'm .3 gn above the suggested max load and safely worked up from 2.2 gns under. No obvious signs of pressure, easy bolt lift etc. However, upon examining the cases in artificial light I think that the primers might be a little flat - even when well under max load. The one on the left is at 2.2 gns under, the one at the right is .3 gns over. What's your opinion on the safety (and the results) of this load work up?
Yeah, I realized that you can get more out of the cartridge - just going by the Hornady estimates which have 3000 as the max load for most powders.Hmmmmm, I don't think so….
178g bullets will surpass 3200fps in a properly throated 300WM.
Next step for your load will be loose primer pockets, no way would I be running that load more than once.
Cheers.

The only thing there is, how do they work in the cold season or winter time? You are very right on working powder the at hight heat with temp sensitive powders. There can be a large increase in pressure with several powder. Especially at the max loading above the manual max load.Primers are definitely flat. You're very close to pressure signs, as long as you worked this load up during the warm temperatures it will be fine during hunting season.
I've never been able to find a reliable source for temp sensitivity factor for this powder. However, in the 23° difference between initial testing and fine tuning the difference seemed minimal. The drop in velocity in the 59.2 loads I accuracy tested earlier in the day vs. initial work up was about 15 fps average. This is within the ES, so who knows if it was even temp related. I'll be shooting at closer to 0° in a few weeks time, but in the field. We'll see how it goes!
