Yeah I looked at Hodgdon's data too and 3.8gr seems way low to me. Since it's lead, I would start at about 5.5gr or thereabouts (the show 6.0gr as the start charge for a 135gr JHP).
Not exactly what you asked for, but 4.5gr TiteGroup under a Berrys 135gr plated is one of the most accurate loads I've ever shot.
