.451" dia. JHP, 230 gr, sitting on 6 gr of Unique.
My lyman 48th puts a 225gr, JHP OAL @ 1.243"...i take that as a Max OAL.
Now the Lee specs that came with the die set has the min. OAL at 1.190" for a 230 gr jacketed bullet.
1.20" is what seems to want to work for my gun.
I checked the Hornaday website for load data, but of course you cant get any from their website.
