I loaded and shot 6mmBR for the first time today.. some questions..

What is the deal with that Remington brass?
I used Lapua brass as the go gauge when cutting the chamber, and the new Remington Brass will not fit in the chamber until I resize it.

I used 33.5 gr W748 behind 75 gr Vmax moly in a 21.375" barrel and got 3100 fps. That was stable out to 50y, but not to 100y.
What do I have to do to get some velocity?

When I started with the BR I asked the same question. Wise people on this forum advised me: don't do the remington brass sh...tuff, so I didn't. In 6br or any other caliber I reload, remington brass has proved itself to be of low quality, compared to other brands, way low!
