[QUOTE="BountyHunter, post: 100286, member: 12"] Good shooting. As most know I am strong proponent of the ladder for extreme accuracy. With that I am talking match grade barrels normally. Couple points that I think this thread makes clear that have been missed in all the debate. 1. You and your gun have to be capable of under .5 MOA to really use the ladder and in many respects you must repeat the OCW even. If you gun is not consistent, then is it out of the node, is it the scatter group or just inaccuracy of the gun? 2. The ladder I have found has to be shot at 300-400 to really be effective. 3. An accurate chrono is absolutely essential. Any technique (ladder or OCW) w/o a chrono you can easily miss the MV jumps and nodes. (that truly is my biggest issue with OCW) That chrono information will help you confirm any suspected tuning node. Dan and I both agree that if you get on one edge of a node, it is easy to come out of tune with temp changes. The chrono will literally show the up and down edges normally. I always start my powder fine tuning in the middle of the node and rarley deviate more than .1 gr up or down, and then go with seating depth and finally neck tension. Maybe change of primers last IF I think it warrants it. 4. If your gun is accurate and you have good bench techniques, I have found that groups at 100 are a waste of time normally. Just one big bughole, some slightly larger and some slightly smaller, but not enought to really make any accurate assessment. So the challenge is really seeing where the node is, therefore going out to distances where you can see POI shifts in a no wind condition (early morning/late evening). BH [/QUOTE]
