My 1st ladder also for 6BRX

[JFrank]

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

Ah yes
I need to get out more

 

[KenOath]

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

what is your opinion on .010 off at 2888 FPS

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..

 

[JFrank]

Yeah
We are a bit backwards in the states!

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

 

[JFrank]

Hopefully it will stay flat until it’s overpowered then go vertical. At least you’ll be able to read it.

I’m like you, can’t leave it alone.
I’ll shoot this one day then figure it’s not good enough .lol

 

[Lefty Trigger]

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

Yeah,
I’d like to put all 10 in that X ring, I just gotta tune a bit more

 

[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

SP, Yeah me too. It don't hurt to freshen the crown once in a while just to make sure the gun is up to it

Just an update
After a bit more testing and stuff I sorted my crap out
Rule one make sure you rest working correctly.. The left hand side of my Farley the grub screw had loosened that held the front of gun in bag causing the gun to move sideways under shots.. Fitted that now haha
I used 32.4gr and 020 jump with my 107gr Smk on weekend.. Did a few good groups and finished 3rd in LG and HG for the 500m fly
2 of my best groups before wind and mirage got the better of me
Flat group is 1.76 inches
Other is 1.9inches and highest score target for weekend of 59.01.
Since the weekend I did another fine tune at 400m (groups) and have gone to 32.5gr and 020 jump is the spot..

 

[JFrank]

Wow
Isn’t that right in between the original shots 4-5?
Great that you spotted that loose rest part, that must’ve been why that seating test was erratic.
Back on top eh mate!!
J

 

[comagutsa]

Yeah J it didn't help with a loose rest haha

 

[JFrank]

They certainly laid down at .020
What happens on each side? Meaning can you spot tendencies of vertical or opening up for your diagnostic tree?
