That is one ugly bullet loaded in a 30 cal case. That said, I played with it probably 10-12 years ago, and it shot very well in 30-30, 308, and 06, with moderate loads of unique. Don't recall what lube I was using, but am pretty sure I sized to .311. Back then saw little use for it, but guess now that Ben has created a few converts, will have to reassess my opinion.
