I dug up an old (4 yrs) thread on this subject and wondered if anyone might have some experience or anything to add.

In the article, Kirby says he believes the large overbores can get improved barrel life by switching from the stick powders to the newer ball powders which he believes are fairly temp stable and will burn "clean" at higher pressures. These include Ramshot Magnum and AA8700. He says these powders dont burn as "hot" as the stick powders.
Kirby, sorry to take your name in vain, but I find this a fascinating subject, especially scince I have a 300 RUM and am considering a 7.
Anyway, was wondering if anyone else has any experience and insight with this that they could share on the subject. Any one using these powders in their Ultra's?
