I have a pretty decent load worked up with IMR 8133, but have also been looking at RE33. I couldn't get the speeds outta retumbo. I really wished I would have bought all the N570 my gun store had last spring.
Only time will tell. Was hoping someone might have talked to them at shot show and had some good news.
I hear that N570 is everywhere up in Canada, so for some reason it seems to be an issues with the US.
Too bad a person couldn't just drive up there and bring back a bunch.....Would be a hop skip and jump for people living in North Idaho. I talked to my reloading shop and they said they were on the back order list.
