46 grs of 20 year old BL-C(2) behind 147 gr IMI FMJ using mixed surplus/commercial brass sparked by 20 year old CCI 200's. Never fails to feed, fire or cycle and does not beat the hell out of the brass, strangely enough. On the other hand the brass is thrown at the 1 o'clock position anywhere from landing on my feet out to 30 feet. Makes brass collection at the range difficult.
Commercial ammo ends up with smashed case mouths and deep dents with the cases being thrown from 12 to 6 o'clock. The SAR4800 functions on whatever I feed her; FMJ, SP, HP, Ballistic Tip, Silver Tip, Match, S&B, white box, UMC etc.. and bullet weights from 147gr to 165gr.
