Hank,
. Not sure I would go out and spend money to test, as it will be a crap shoot.
A 250 at 1230 would seem to me to be pretty darn close to max pressure.
I figured it was a crap shoot, but I have a bunch of 250 gr WFN's for my M92 Levergun so I thought I would give it a try.
It has been my experience that I usually get more velocity out of cast bullets than jacketed, but I backed off a bit after the 9.3 gr load anyway.
