Satterley Test

[rbell0883]

Greetings to all!

First post on here, so bear with me. I have decided to do a Satterley test on my rifles, and I have the results put into a graph. I think I have some pretty easy ones to read, but there are some I feel are inconclusive. Can you guys look over them and give me your opinions on them?

The M1 Garand was done twice as it was my "guinea pig" for the testing. So I duplicated it twice to see if there was any inconsistencies. But the rest were a one time deal.

Let me know what you guys think my loads should be, and I will see if I'm reading the results correctly...

Statistical analysis requires adequate data.

Shoot 5 at least shots at each of those points and you will have something meaningful to look at for starters.

You likely are bristling up right now as you read this...so prove me wrong. Go back and shoot the same test again and see if it looks the same.

That is all.

I thought the exact same thing, and I actually plan on doing it to see if the test actually works... But the whole point of me doing it this way was to find that sweet spot with 10 rounds, vs guessing with 50. Using the Accubond LR bullets, they are a little pricey, so I'm trying to cut costs where I can.

I may try it again with the 308 and the M1, but doing both tests with the M1 showed strange results... The bolt guns seemed to trend, within reason, like I figured. The M1 really threw me for a loop with the results...

Scott Satterly himself doesn't do it that way anymore.

The guns and calibers it works with are already extremely consistent and accurate, and most are some form of 6mm or 6.5mm with a medium case capacity and brass prep has to be extremely consistent.

I'll save you some time and money.

Find your max charge, back off 1.5%-2%, and work on seating depth from about .045-.070" off the lands.

Something in that area should group and be safe to shoot no matter the season.

When I do a ladder test, I run two sets. Any single round can be low or high and yield deceiving results. If I see dramatically different results in at a given weight, then I may run a few rounds there again to see where they land. Invariably, I'll find one or more areas to play in. Then I'll load sets of 5, find the best one or two, then validate with 15-20.

I figured it was too good to be true... and the results I got were nowhere near as consistent as I hoped. Some were, some weren’t. I do believe it has a place to do it, and my brass prep was pretty meticulous (short of weighing each case) but I have to have more velocity out of my 6.5 to use it. The 308 seemed to give good results, and I may run with it. I was hopeful at least...
