[QUOTE="MudRunner2005, post: 1150265, member: 12995"] Seating the bullet into the lands can, and will cause excess pressure and pressure spikes, which can sometimes appear to be early pressure signs and can also cause heavy bolt lift, cratered primers, ejector marks, etc... Try seating the bullet away from the lands some (.015-.025") to see if the pressure signs subside or go away completely. I can't guarantee it will help, but it's worth trying. Another thing, OAL is not a good way to judge your cartridges, as every brand and model bullet all have different shaped and length Ogives and maplats (the tip of the bullet). Measuring your cartridges from base-to-Ogive with a comparator tool is a much more accurate way to measure cartridge length, and when you use the comparator in conjunction with a cartridge OAL gauge, that is the most accurate way to measure your distance to the lands with a particular bullet.
