The scarcity of H-Extreme and Alliant Reloader series of powders helped the Enduron line catch on much more quickly than it would've under "normal" circumstances.

More choice is a GOOD thing. The Enduron powders are made in Canada which is also a good thing, don't have to wait for boats of H-Extreme powder from AUS or Alliant Reloader series from Europe.

I loaded some 300 Win mag for my grandson with IMR 7977 and over the chrono it was the most consistent load I have ever shot. Loaded with 180 Ballistuc tips and because I had Federal brass I loaded down with 72 gr of powder. It averaged 2910 fps out of a 24 inch barrel, and I want even tell you the extreme spread because I dont want my credability questioned. :)

Am I right in believing these powders would work well in '06,.270 etc as the 7RM is not a true magnum length cartridge?

7977 and 8133 are probably too slow in the ‘06 based cases unless you’re quite heavy for caliber and/or have a long bbl. QL says case-fill happens prior to pressure. Neck down the ‘06 to 25 or 24 and 7977/8133 w/heavy bullets shines brighter.

It’s not just length, girth matters as well both projectile and brass vessel girth.

^^^^And that is the exact type deal which keeps me coming around here. It's slightly above my head as I don't understand "QL", don't roll my own and consider myself an enthusiast not an expert: I'm close with L/SMB which allows me to easily catch other faggoty species.
