[QUOTE="FURMAN, post: 1372874, member: 26535"] OCW is best done at 100 yards and the picture you posted is not an OCW. Ladders, in my opinion, are far more valuable and best performed as far as you can shoot out to 1000 yards. With the OCW you are ONLY looking for the widest node you can find as far as point of impact, NOT vertical and should be followed up with velocity checks if not done at the same time as the OCW. The "node" with two or three identical points of impact(over as many powder charges) will almost always have a low es and sd in velocity. Ladders are mostly focused on vertical but as Alex has pointed out in his threads about the ladder big horizontal with no wind is usually caused by incorrect seating depth. Pick a load development method and stick with it. I think it is easiest for knew shooters to perform the OCW especially since many do not have access to the ranges required for best ladder results.
