Unrelated question. When shooting at the range and doing my ladder test, between ladders is it ok to use a bore snake on my Bartlein Barrel, do bore snakes hurt the barrel at all being that they are dry or should I use a rod with a wet patch?
When you do a ladder test you want everything the same. I usually do multiple ladder tests..here is my method.
Start with a clean gun. Shoot the test at longer ranges if at al possible. Min 300 yards. i shoot mine at either my 750 yard berm or at 1000.
Shoot at least five sighter/fowler/warm up shots. You need the tube warmed up before the first shot. Time your shots.... if you are shooting a big hot rod that heats things up fast, or it is very hot and calm, take 2 min between shots. Try keep the tube ROUGHLY the same temp.
When you are finished with the first....clean the gun...shoot the fowler/warm up shots and run the test backwards...high to low.
If you shoot a third..do it all again.
The point is that you want to keep all of the parameters of the tests as close to the same as you can. I don't worry about the wind, a tripple ladder test might take a couple of hours. And don't look at how groups of the same powder charge did, look for clusters of shots of DIFFERENT CHARGES that clumped together on the same target.
