Working up some loads for my 77R tang safety and just curious about the seating depth. Some say jamb 'em into the lands, others say back off 10 or 15 thousandths. Is it just a trial and error thing or? I like working up loads but with the scarcity of some items I want to keep the use as low as possible. Would you move 'em 5 thousandths at a time or less? Right now I've got a couple of pretty good loads worked up using 4064 and 50 grain Berger FB Varminter bullets seated 10 off the lands. I've shot one 5 shot group that measured .705 and 3 of those were .385 but I haven't been able to repeat that yet but have only tried it once and got just over an inch. Anyway, just trying to figure out where to go next. The load mentioned here was 39 grains of the 4064 and I also loaded 37 and 38.5 with nearly the same results.
