Matrix Ballistics - Anyone use them?

[garrenj]

Looking around for a new long range set up for next year and found these guys. I was looking into the 7mm and then got to comparing these to Berger's. These bullets seem to have a much better BC than Berger's in the calibers I was looking at.

I currently load the 150 bergers for my 270WSM, but was thinking about giving these a try. Anyone ever used them before? Thanks
