Most definately. I was shooting 98gr of H1000 with 180gr bullistic tip in one 300RUM. 2gr over max, but shoot 3350fps, no pressure signs, brass lasting 5 or more fires.

Then I had it rebarrled with a krieger and I could't even reach 95gr without pressure signs.

I can't emphasize it enough, with a new rifle, start low and build your way up again. We had a rifle incident at the range. A rifle can blow up.

Another lesson I learned is if you build a load in sub freezing weather, be careful shooting that load in 90F day. I had a load that would shoot great when I made them at 12F, but one summer day it locked my brass up cold in the chamber.
