what do you mean I've tried it but never found a
rifle that it shoot well in
t

I found it to be temp sensitive in 30-06.

I used the Search feature to dig this back up.

In short, it is not what is in the Hornady Superformance factory loads and IMO, handloads tend to need less than what you would weight from factory loads, for 270win, at least 6-8 full grains less, which makes a factory charge dangerous in a handload. I blew out the extractor in my Tikka doing just that. I would not hesitate to try the few published loads they show on the powder jug. Otherwise, you'll see some good loads and info in this thread.

I've been using it to load 108gr ELD - M's in my 6mm, they shoot great but my shooting spotter said he could smell something after every shot.
Then the next day when I went to clean it the muzzle break was full of that
white/green powder rust stuff.
