Which method do you use in developing a handload?
I use the ladder method shooting 5 round groups at each charge weight. Once I'm within the velocity range I want, I look for the groups that are the tightest. Then I'll rework some more loads around those charge weights, and do them again, sort of as a check. I use grain weights of 0.3 increments initially, then 0.1 for the final testing. After that I'll play with seating depth and neck tension a bit.
Ladder method over a chronograph to determine nodes (based on velocity more than impact on target). I typically use a seating depth of .015" and use .3gr powder graduations.
Then I'll shoot some groups over the chrony to check the consistency.
I'll fine tune with seating adjustments, but .015"-.025" is usually pretty close to optimum in my rifles and the components I use.
I use the Ladder method to find nodes especially the highest velocity node.
I then switch to the OCW method to find the widest node to help with temperature changes. Also I now shoot all loads out of an ice bath regardless of the time of year, except for colder days during hunting season.
Gday to all
I ve heard a bit about this ladder method of handloading but cant seem to find a site to explain how to use this method. I ve also seen linked sites people have posted but cant get into them. Can anyone please tell me where i can find info on how to use this method.
I started out doing the OCW, recently tried the ladder a few times and I'm torn between the 2. Maybe it's because the rifles have a LOT of freebore that I'm not 100% satisfied that either method is that much better than the other.
Go here and read on.......Ladder Test for Load Development -
The links on those pages are no longer working.
Did anyone cut and paste it to their computer for future reference?
I uploaded the document that I had saved re: the ladder test. The formatting is pretty close to the original word doc.

Hope everyone can see this document
oops! I shudda checked things completely.
I'll snoop around.
OK here's a couple.
First just to confuse things is the OCW method.
Note that the OCW and ladder test folks argue quite a bit. Kind of like Ford and Chevy folks

This took a bit of hunting but I tracked'r down.....
I use a bastardized combination of the two, using the Ladder to get close then the OCW to get spot on. It works for me.........
I just tried the ladder test for the first time yesterday... I used a two shot group at 200. It seems that it would be better to get out to 3 or 400 yards for a good ladder test, so I'm going to start using a combination of OCW and Ladder. I used to always pick a powder and bullet, then start doing 5 shot groups till I started seeing what I liked or had a sticky bolt... lots of wasted ammo - well, I guess I still had fun shooting paper lol!
