The ladder test is a good article but it looks like from the pictures shown that the rifles used are customs jobs that the average guy could not afford with a mortgage, kids and understanding wife ,etc. So what would i look for in the average load development at 100yds? I have tried the ladder test and found my results to differ from the published data as i shoot a factory rifle out of the box. Plus the extra expense of firing so many rounds to develop a load? My loads were not as published because the loads were scattered. I shot from a solid shooting rest on all the load development. I changed nothing from OAl to powder or primers. They all grouped about 2 1/2 inches at 100yds. From the recommened start to max load. Most of the grouping was to the left and some were lined up dead center but high at 100yds. Some loads were touching which were about 1 gr apart and some would be about 1" apart or more that were 1/2 gr aprt? Loads were 1/2 gr apart on development. I did not change from my previous zero which was at 200yds. So what would i be looking for ? Am I missing some thing here?
