Have any of you had success with any of the new IMR Enduron powders? Particularly in 260 Remington or 222 Rem Mag?

Have not used them, just read the reports in a magazine and they were awesome according to the author, HOWEVER, SOME OF THOSE POWDERS WERE RECALLED!!

I've been using 4166 for several years in my .308 with 155 grain bullets. It shoots as well as any other powder out there but the accuracy window was a little narrow, so you'll need to work up loads in .3 grain increments instead of .5 which is most popular.
