I just got back from a quick trip to the hills to test out Seafires load for the 200 NP and H4831 SC.
Started at 60 grains and moved up to his load of 63.5. End result, out of a cleaned 22" barrel I got 2,750 mv. I spect that once that bore dirties up a bit that it will be pushing 2,800 mv.
No signs of pressure at all from the load.
The rifle is a 700 Ti and I have a scope on the way for it. (I shot over the chrony w/o a scope.) Once I get the scope on next week. I'll take one piece of virgin brass and my loading stuff to the range and see how many times I can shoot it without the primer falling out.
