In ctgs. & with the bullet weights that works well with it, BLC2 can be utterly amazing in the ballistics it produces.
I noticed it as listed as producing over 3,000fps with 120gr., with original-type pressures of 47,000CUP.

This powder works in my 9.3x57, 9.3x62 and .375/06IMP that I know find out has very close to a .375 Brown Whelen chamber.
In all of these, it gives top speeds with the medium and heavy bullets. In the smaller ctgs. that can use even slower powders with the heavy bullet, BLC2 would work very well with the lighter bullets as it seems to do for VonGruff in the 7x57 Mauser.
