The thread is about finding an accurate load. While many different approaches can be used the Audettet ladder test has been adopted by some. While I have used it I find that doing a pressure ladder using a single shot at each increment, as I have shown, works best for me. I have worked up a number of loads that shoot sub 1/2 MOA, mostly in wildcat cartridges that I have designed that have no manuals to follow, and do not run pressures that cause sticky bolt or blown primers.
It does not matter what discipline you shoot it is a fact that a load that will consistently shoot Sub 1/2 Moa groups will do better than one that won't do 1MOA groups. Combine that with a stable load, that consistently shoots a low Extreme Spread, especially if the Standard Deviation is in the single digits will do well at longer distances. Once a good load is established then it has to be tested to the maximum range it is going to be used to ensure that it remains stable. I have never had a good load, developed in this manner, that failed to perform at ranges that they were designed for. As well a good load will shoot well in most any rifle and I have many ladder targets, and follow up groups to illustrate that.
That being said I would be interested in finding out how you find a good load, especially for long range, without being able to shoot good groups at closer ranges.
