This messed me up at a 3 gun match once. I had my carbine sighted in at 100 with 77 grain match ammo and accidentally grabbed a mag of 55 FMJ that was moving significantly faster. When engaging some 4" targets at 175 yards, it was enough that I discovered after 3 straight misses that I was barely high left. A slight correction corrected the point of impact but after I had waisted 10 seconds trying to figure out what was going on

I don't even have 55 gr FMJ anymore. The POI shift from 77s was too exhausting.

My attention has turned mostly to XBR for heavy 5.56 and .308 loads lately. Lots of catching up to do in the workshop over the next few cold months.
Going back to the original question... It's really easier to say which powders I don't like, or which ones are less optimal.
Anything from Reloader is not acceptable due to the crazy temp sensitivity. WIN748 is temp sensative too. But it's a SUPER low flash powder. Other than those examples, I've not run into any powders that really bothered me to use.

Have you tried any of the new Reloader powders (e.g. 16, 23 and 26)? Supposedly they address the temperature issue. I’ve been using RL 23 in .300 WBY and 6.5-284 and have not seen an appreciable drop in velocity thus far. For info, I developed my loads over the summer when it’s usually well into the 90’s and it’s now currently hovering around freezing most days.
We messed with RE19 for 338 WM when we were struggling. There was an issue with temp. I'd have to see if I wrote it down.
This is interesting. I've shot a lot of 8208, but never in .308. It strikes me that XBR is a little fast... especially compared to Varget. But we shoot the heavies in .223 with XBR sometimes.... so who knows?
