Hammer Bullets

My 300 PRC is my shinning star. 199gr HH with80.5 gr H10000. I'm worried that I'm going to mess it up somehow.

I was using 79.2 gr of H4831 in my 300 PRC with the HH 199 last fall, but that is a pretty hot load. I would not recommend pushing that hard with H4831 unless you like throwing away your brass.
I was averaging about 3060fps in a 24" barrel and that load consistently shot 1/2MOA. Easily dropped an elk at 100 yards with that load, but I have now acquired slower powders and am getting the same velocity with less pressure. I am really liking N570 and N565.
Assuming you also have a 24" barrel, you should be able get 2950fps with H4831 without sacrificing brass life. Any faster than that and I think you will start seeing some pressure signs.
