Re: Ladder Test Question ???

100 yds for a ladder test is just about a waste of time as everything is packed in one little area. Bare minimum would be 200 yds, 300-350 would be best.

Re: Ladder Test Question ???

probably be helpful to run a "search" on <font color="red"> ladder </font> as there is a lot of information on the subject being as you are going to be shooting so many guns and so much has been written on it at various times.

My way is much better. [img]/ubbthreads/images/graemlins/smile.gif[/img] And you do it at 100 yards...

Be sure to read the rationale behind the round robin firing sequence, as well as the Audette ladder versus round-robin firing sequence.

green 788

I like your way of finding a load, but man its confusing. I read it over twice and still scratching my head. Usually I just pick a powder, primer, bullet, then start at the lowest charge and work up in 1g increments. When I find the MOA load at 100 yards, I will then go up or down .5g to see if that makes or breaks anything. Seems to work for me and a lot less confusing. Usually I'll find a load that will shoot 1 inch at 100 yards while only testing 4 loads or about 12 shots. I tried the ladder test on 1 rifle, and it was more hassle and I didn't learn a thing from it. It did not give me good groups, but I think that was more the rifle than anything.

Re: Ladder Test Question ???

The ladder test results end up being confusing for many.

I'm going to post a link to a pretty much textbook OCW test at another forum. He shot six graduations, and (for whatever reason) chose to go right to left on the bottom row, then left to right on top row. OCW was decided to be 47.2 grains, and this load has shown the continued ability to shoot into one hole--from a factory rifle. (Admittedly a very accurate factory rilfe).



And below is a sketch of how the typical OCW test should go.
