I haven't even seen it yet. I seem to focus on the powders that I have known and only look for them. The write-ups look good though.
I'll be interested in hearing what folks think of it and the other new ones from IMR.

Looks like there are at least 3 new powders in this "Enduron" series.....4166,4451 & 7977. According to information, they should be on the dealers shelves in early 2015. These 3 feature an additive for copper fouling elimination.

I have worked pretty hard on my loads over the years and have settled on components that give me the performance I want. If I to get a new gun or change bullets, I would surely give them a try. Bet they are at the top end of the price scale.

Some write ups on longrange hunting. I found some 7977 to use in my stw the other day but passed. I think I'll try some RL26 or RL23 first.

I plan on working up some. Going to start loading some time this week. Edit..I have a 300 load I like already, going to work on the 308 now. My 308 seems to be on the finicky side.

I've ranged out a little into powders I didn't normally use.....IMR 4320 and RL15. Both seem to work well in my 338-06. Starting to see more powders on the shelves.
