make a load ladder at the bottom of the load spectrum working up with the bullet jammed into the lands - my gun seems to like 0.025". You may see pressure sooner than without jamming into the lands, but I went up to 32 grains of CFE223 under a 123, had a wildly compressed powder charge, and jammed 0.025" and still had no pressure signs. My good load with cfe223 is currently 29.8grains IIRC, COAL is 2.245" or something analogous to that. That particular load is about 1.5 minutes lower at 625 yards than Hornady BLACK, so it is moving a tad bit slower.
