Interesting thread in Art of the Rifle forum, about SAR .223 rifle blowing up with Seiller & Bellot (sp?) ammo.
Contributors referenced similar problem with other types of rifle using this ammo.
I have a couple of boxes of S&B .223 ammo in 55 gr. on hand for my Colt AR-15, and several hundred empty cases for reloading.
Any information on this? Is it peculiar to the ss109 load? Could it be a brass problem?
I'm gonna worry about this until I get some more information.
