Has anyone ever worked up a load with no published load data? Did you use a closest match (published data) and cautiously start at the bottom stopping at pressure or desired node?
Long version: I wanted to try the 143g Lever Hammer bullet with my supply of Hornady Leverrevolution powder but there is no published data for Hammer bullets. I emailed Hammer and they suggested I start with the Hodgdon data published for the 140g Hornady MFTX (29 min/ 34max). So I did... and while it worked I found no signs of overpressure at the listed max loading I was disappointed that yielded a velocity thats usable but low for a lighter bullet at 2258fps. My current handload is a Barnes150g TSX @ 2360fps I was hoping to at least meet that or hit 2400fps with the lighter weight Hammer...
Im guessing I will get a scolding for asking but, should I try to creep up on that in 0.1g increments?
Heres a pic of the min (left) and max (right), I interpret the max (right) as a #2 on the "larrywillis primer pressure scale", what do you think?

Right: 34g HLVR @ 2258fps
