[QUOTE="Alan Griffith, post: 87870, member: 4686"] I currently load my Rem 700, 30-06 with 57.6 gr H4350, WLR primers, Win cases and 180 Nos BT seated to 3.395" (approx .308" seated into neck). I've determined my dead set OAL with the ogive up against the lands is 3.556". 57.6 grains, though book max is not max in this rifle with bullets seated out to the before mentioned 3.395". I'm wondering if, any amount at all, you would back off the powder charge I mentioned and work back up again. I realize their are two opposing factors at play. The increasing OAL increases case capacity and should reduce pressure and velocity. The bullet, not given the running start into the lands, could cause an increase in pressure. It will probably be wise for me to back a bit, but how much? I don't wish to have to put too many bullets down range to determine my max pressure. Big Al [/QUOTE]
