Satterlee Load Development and Testing

This test has proven to be a winner. It’s worked every time I’ve used it and continues to perform. More data with less shots. You can do this Satterlee test, find the node and load 10 more to verify the data. Start to finish in 20 rounds. Hard to beat that!

I use this method all the time now. My first 10 shots in my 6.5cm were the test. The next 5 went into sub 3/4″ with an ES of 20 and an SD of somewhere around 6
I’m sold.

I like the approach, instead of say shooting 5-10 rounds at each load level, maybe .3 grains apart and looking at group size; you shoot 10-20 loads and look for the ‘flat’ spot in the velocity ramp.
I’m a closer to a plinker than a marksman; I’ve been looking for a reason to by a chronograph, besides I want one, this may be it. 🙂

It took me a while to buy a chronograph, but since I bought it I’ve used it FAR more than I imagined I would.

I’ve seen several references to this method lately. I’ll be doing some rifle work this fall, and will have to check it out.
