Oh yeah - so it is. Both are very soft loads. I see they only go up to 60,200psi for max pressure with some other loads, but they do list 66.0gr. BLC2 with 270gr. at 53,100psi.

I see they load 66.0gr.BLC2 with 270gr. bullets in their 9.3x62 data @ a mere 2,548fps & 47,400CUP - wonder why they stopped at that pressure with the larger cased .376 Steyr? That does explain the lower pressure generated, though.

Have you chronographed it?
