Best way to test loads?

Hoping to get some time to work up a few loads for my 7 mm stw today. Was going to work up five then make some adjustments then work up five and so on. What is the best way to test the loads. Squeaky clean barrel, shoot the first five, clean and so on? What do you guys suggest?

Re: Best way to test loads?

For developing a load, its the ladder test for me. Also known by the incrimental load development test, and others.

The short description would be shooting a series of rounds, each with different powder charges loaded in increasing incriments of charge wt in an attempt to find vibration nodes that minimize the dispersion caused by varying charge weights, while allowing an accurate, repeatable load to be found for a rifle, with a minimum round count being fired.

Ive got a document that does a passable job of explaining the ladder test. If you would like a copy, id be happy to email it to you.

Ive been working with a 7STW a lot lately. if youre interested in componet suggestions for an application...

Re: Best way to test loads?

I agree that the "ladder test" is relatively efficient and accurate.

What I would consider as better method, due to less emphasis on any individual shot for decision making, is Dan Newberry's "OCW" method. Here is a link to Dan's site:

I have used both methods extensively and while either beats the old methods by far, I find Dan's more reliable and easier to interpret.

The beatings will continue until morale improves.

Re: Best way to test loads?

I don't think anyone has answered your question yet. The correct answer is probably "clean and cold," but I believe it depends on how you will use the rifle. For instance, if you will be doing long sessions of prairie dog shooting with the barrel dirty and hot, then that's how you should test. For target shooting at extreme ranges, you probably want the barrel clean. I am mostly a deer hunter, so it's the first shot that counts and that will be done with a cold barrel. Frequent cleaning at the range seems like a waste of time to me and I haven't seen any significant difference in accuracy at normal ranges, so I don't do it. A cold, dirty barrel is my standard. When I clean the barrel between shooting sessions, I always fire a fouling shot before I start any accuracy testing. I go hunting with a dirty barrel that I have run a dry patch through to remove the big crud, hoping to simulate the conditions under which it was tested at the range. Other shooters will have a different rationale and I would expect to hear from them here also.
