[QUOTE="Outlaw6.0, post: 643973, member: 23486"] Running the 338 RUM at a restricted OAL (AI Mag length), I had [U]serious[/U] pressure signs @ 92.5grns of Retumbo with the 300 Sierra. Lost those two cases, didn't pop the primers, but while seating the new primers, they wouldn't stay in the case!! Start in the 86-88grn range just to be safe. My load right now is 90.0 (yes ninety) of Retumbo FED215M Rem Brass 300 Sierra 5-Shot average of 2780FPS w/26in tube [/QUOTE]
