I am quite baffled on something and would welcome any input anyone might have…I got a major warning sign at the range on my first shot of this load: Speer 120-gr BTSP (.257) 48.5-gr H4831sc CCI BR2 R-P case, trim 2.488” (1st reload) Savage 111 I aquired the bullets some time ago and had called Speer to get starting and finishing charges so I could play (start 48.0-gr H4831sc, quit 52.0-gr H4831sc, 2958fps). Anyway, blown primer and stuck bolt !, took some good muscle to get open to see the extractor had torn off part of the rim due to the case was stuck. Bolt face was lightly marred around the ejector hole . Nevertheless, I wont be using anymore of these bullets in the near future and may replace bolt head. Very pissed to say the least, and I want to call that guy at Speer and tell him to go pound salt ! does anyone have the Speer book that could verify for me what the actual min/max charges are for this load? Any similar experiences? thanks for any help..
