My lot #49949 of WC 846 is a lot closer to H-335 than BL-C(2). I scared myself pretty good with what should have been a moderate load. Ain't gonna post it here for obvious reasons, but 165 grain bullets ain't spozed to come out of a .308 at near 2900 fps. Even at that, the cases weren't showing major signs of over pressure. Primers were as flat as I will allow, but they did not flow into the firing pin hole more than is normal for that rifle. No ejector cut mark. Extraction was normal, but I was shooting a Mauser.
Listed starting loads of BL-C(2) may be at or over max with this lot.
