That load oughtta rock back a little.
I just bought a SBH 4.62" and was wondering what to expect from it, velocity-wise.
Are you using a 1.610" OAL or longer?
I am using the Oregon Trail 310 WFNGC @ 1.640" OAL, it's pretty sporty.
9.5grs of AA #2 or 9.5grs of Unique shoots really good through my 4.62" SBH with that bullet.
I have been using the WLP with H110. I have used magnum primers in the past but these were all I could find and they work well.
I would like to pickup a 30mm UltraDot before season starts.
