[QUOTE="FURMAN, post: 1496487, member: 26535"] I do not have near as much experience with the OCW(which is what I believe he is actually trying to do) as I do ladders but the ones I have done I have not seen that much poi change across a grain of powder when the load is good. I personally would do .5 or even .3 grain increments but would expect to see something usable over 1 grain. I would expect a good stable load to have a very small poi change between at least two of those groups. Obviously the group size would change. I have done the OCW with a known good load found with a ladder a couple of times and the avg poi does not really change just the group size. Obviously he can do what he wants but if my rifle/bullet/powder put that on a target in front of me I would move on. On a few OCWs I have done the groups were absolutely horrible but the poi was very consistent. That is something I can work with. All it needed was seating depth test with the center weight powder charge and I had a great, repeatably, long range load. [/QUOTE]
