The like that it is the same charge I use for 77gr loads and requires no adjustment on the powder bar; only to move to preset marks on the micrometer seat die.Quote:

The only time It messed me up was in Patrol Rifle Class. My instructor was critical of shot placement and so my POI shift was a minor nuisance when I switched ammo. The ammo is another story...Quote:

A slight correction corrected the point of impact but after I had waisted 10 seconds trying to figure out what was going on :rolleyes:Quote:

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.Quote:

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.Quote:
