HELP WITH SATERLEE VELOCITY TEST

[redneckdan]

Hey Redneckdan,
You say you reload the high load for hunting.
That's my goal too. How many loads at .1 grain difference do you load above and below your high node?

I usually go one increment below and above. Say I loaded in .5 increments and 50.0, 50.5, 51 showed a good node. I would load 49.5 to 51.5 in .1 gr increments to make sure I captured the whole node. Since this is an attempt to get a look at the whole node I might only load 3rds each. Shoot those and say we got best SDs @ 50.7 to 51.1. I would load 5 each at 50.7 to 51.1 and run the statistics again to pick the best SD.

I have a featherweight 270 that showed three accuracy nodes at 100 yards. Took a target to 200 yards and easily found the best of the three there. I usually use .4 grain increments so that I can then go to .2 increments and then .1 if I want but not required on a medium range rifle setup. Big bores like the 338 WM I use .6 grain increments starting out. Go for accuracy first, in my opinion it is much more important than the lowest SD you'll get.

53.1 to 53.7 is a good node. It's 4 shots wide which is typically what I see most often. So I it was me I would drop 53.1 and 53.3 and go right in the middle of 53.5 and 53.7. So I would load 53.6 and do a few seating test around this charge. Once you have the best seating seating depth I would load that depth with 53.5 and 53.7 also and see what is best. This process works for me very consistently. Let us know how it goes.

Hey Shep, would you shoot these different seating depths with or without the magnetospeed attached?

Gotcha...Thanks

I wouldn't shoot any groups with magspeed on your barrel. It does effect your harmonics. Just use the speed numbers to get your starting loads. Once you have it dialed in you can check your velocity and es/sd again.

You got major issues at your case neck in the first picture.

Hey Stammster!
I thought it was carbon. I cleaned it off with rubbing alcohol. Sure shooting there is a slotted hole there on the neck. I guess I found my max!
Good eye dude!

When I do my Satterlee test I use . 02 gn on everything. I really want to see where that node starts and ends. I don't shoot anything in my guns that hold more than 62 grains. I could probably do . 03 on the 62 but to keep it simple I just do . 02. About 5% of capacity is good enough for the ladder. I know I will get some flack on this but I do seating depth test with 2 shots each. You can actually see the bullets get closer and then start to spread out again and then come back together again. I've shot compatition for a long time a feel confident doing this. Once I see 2 or 3 groups stay tight I use that seating depth. Then I verify my load with longer shot strings.

That little hole in your brass wasn't caused by too high of pressure. It most likely was a flaw in the brass you didn't see from the start. There are always one or 2 like that in Winchester 300wsm brass per 100. Sometimes they will iron out when shot and be fine sometimes they open and leak. I just pitch them from the start.

25WSM did you mean to say 0.2 gn

The problem I have with the Saterlee method is that Saterlee said he doesn't use it anymore

Hahahaha!---Exactly! He has talked about it on a number of different podcasts. I would bet a paycheck that if he could go back and erase that video from existence he would.

1) He didn't do it the way most interpret it in the first place. The 6.5 Guys video didn't bring out all the details about the way he was doing it then.

2) The man himself doesn't do it that way anymore.

All of you devotees to this method... you "enlightened ones".... are chasing rainbows and unicorn farts.

Nobody has ever been able to explain to me how a powder burns more consistently at one point... then burns inconsistently at a point a few tenths higher... then magically burns consistent again at a few tenths higher still, before it falls apart again. Tell me please what the mechanism for that might be.

No one said that the "burn rate" varies. Unless you're changing powders randomly in the same test and expecting a predictable result.

I haven't followed this drama—what method does Scott himself now use for load development?

Bob, there is a Greek proverb I will attempt to translate. "half knowledge is worst than ignorance". Don't waste your time tying to educate those who do not want to learn. They have already met their capacity. Save your energy for those with open mind and thirst for knowledge.

Good Shooting!!!
