My 1st ladder also for 6BRX

[Bc'z]

.005 jam is looking good.

 

[Lefty Trigger]

I find that when testing a load that I have settled on the speeds are different than the ladder test. If looking for that exact speed you may need to bump up or down .1 to see if you can find it, if it shoots good run with it.

 

[comagutsa]

I’m struggling and here’s why.

.015 jam is fairly flat the next looks like a reverse L than .005 is pretty good again.005 off is a bear paw etc. and this goes on through out the test.
I’m not seeing a pattern or tendencies to follow creating the diagnostic tree, you must not be on the powder node or may be just typical of 107.
Just my 2 cents Bro

Yeah speeds were down from ladder. It has rushty and I scratching our heads.. I will be testing the better of the 2 nodes and slowest tomorrow. Will let you know how it goes..
Fingers crossed

 

[Lefty Trigger]

If you dropped out of your node your chasing your tail with the seating depth test. You should find that node and retest it with more rounds to make sure it holds. When I first started I was told to find the depth first then the powder node, huge mistake! I was getting nowhere and actually bought a new barrel for a gun I thought just would not shoot, nice barrel but not sure I needed it. Also learned the hard way how poor quality sizing dies can really muck things up!

I wasn’t confident with that node from the start,as stated earlier an ES of 33 over 3 shots had me concerned during the ladder test...My pick was the lower node from the ladder which held good ES and elevation for all 3 it was shot in...

In my experience it is not typical of a 107, in fact it’s the opposite...

I don’t think it was ever ‘in’ the powder node, the ladder was inconclusive and needed further testing IMHO..

 

[comagutsa]

Yep I'm thinking more testing is needed..
Got down set up before sun rise again.. No wind but a little bit foggy
Jam was crap today haha I was using the 31.9gr load but again speeds were a little slower than when I tested.
Last 2 groups the barrel mirage had hit me so I had to make sure I was in right spot and had to wait between shots..
Think I need to start again with load I think.
It is getting colder here so I think it has messed me up

 

[Bc'z]

.005 off says feed me more powder.
What does touch look like?
I was liking 5 in, now 5 out.

 

[Bc'z]

Why does the date on the target board say 8/5/19 ?

what is your opinion on .010 off at 2888 FPS

If seating depth was solid I'd say 1 of 2 things. Wind or punched trigger.
There 10 thou variance between 5 in and 5 out.
I still would like to see what's in the middle.
He did say velocity was down .005 out is saying feed me, which would get velocity up.

......

day-month-year (DD/MM/YY) format.....

The date would read 5/8/19 for you guys we put day, month then year..

15jump looks the one to go for from that test.

That is date then month then year.. The real world does it this way
Yeah speed when I did ladder for 31.8gr was 2903 and 32gr was 2918fps p, you would think 31. 9gr would be somewhere in the middle. So I think I need to speed it up a bit.. I'm going to reload and do speeds again as its getting colder every day.. When I did ladder it was approx 22c day.. These seating test where done about 6 to 9c early in the morning..

 

[Lefty Trigger]

I like the .010 off better and maybe bump the charge weight to see if it improves. Could also try .002 on either side of the .010 like .008 or .012. But I cant leave anything alone...

 

[comagutsa]

I have some loaded up again to see what speed is doing at 010 off lands.. .. But its back to work tomorrow so won't be able till test till Sunday if I'm lucky

 

[Lefty Trigger]

That a 600 yd target? That's awesome, targets like that are my goal at 600 yds.

 

[Bc'z]

Can't tune the wind my friend.

 

[Lefty Trigger]

Can't time the wind my friend.

I struggle the most trying to read the wind and compensate for it. I need a 1000yd "indoor" range...

Think about it, you will not learn to read or shoot in the wind in an indoor 1000 yd range. But with that thought it would be nice to have that range to work up a load. Besides did the you ever hear, The wind is your friend.

 

[JohnMill]

I might do a fine tune that way.. Going to do seating next (with 32.4gr). then fine tune I think

I'd like to see you do a single aimpoint at your longest distance, color code the bullets for each charge weight, and shoot low to high one shot per charge weight, then high to low, then low to high again. That should even out the changes in conditions. Ignore the wind. One of the colors will likely line up for vertical. See https://www.accurateshooter.com/technical-articles/long-range-load-development/
Any deviation will skew the results. I seen this 5 times in class and understood it better each time.

[JohnMill]

You guys crack me up!

A second way to have another look is to color three Bullets of each charge and shoot them at the same POA in a round robin while not changing your set up.

A third world be (non round robin) at individual dots in a vertical target format therefore only adjustment is elevation.
Decreased tracking variables is a plus.

Have fun over there y’all

Sorry, SP
I sort of repeated your message later on. Hope one of us gets thru to him. He always trys to help others
