[QUOTE="MarkA, post: 1454633, member: 5220"] I do. I just adjust to speed shown, start with something in the 52-54 kpsi range and work up load with good chrono. When your at predicted speed you will be close to predicted pressures (even if it takes a bit less or more powder to reach predicted speeds). Then when I have fired brass just check with chrono to see if speed changed due to fired brass and adjust loads accordingly. Case capacities in the 40 grain powder class will not change much if any from fired to unfired brass if brass is consistent. If this is a new barrel keep an eye on speeds periodically. As most barrels tend to speed up at somewhere between 100 and 150 rounds normally. If speed is increased so is pressure. I had to come down 1 grain with H4350 in .260 Rem with 130AB at about 130 shots. Was cleaning barrel bout 30 shot intervals and keeping eye on speeds. In my .260 best seating depth with the 130AB was found at 70 thou off lands. [/QUOTE]
