I would think you could reduce the jump .010 and try the 29.4. How temp stable is the N140?

I keep forgetting your not imperial, so your SD of three is on the high side of optimal. Bummer on the pressure though. 732ms is not that bad for a 130gr I suppose. Glad someone else is getting good results with them. Now for accuracy at 600m+

[Second]

Have checked the numbers again.

I will back one step and do another load development and see if I can find a better speed node.
I usually do two tests before I check a selected load for speeds and SD/ES. This time I skipped the second test and went straight for two loads to check for SD/ES.

But the second test will be done around the same loads 28,3gr and 29,4gr since it clearly is a node on those two loads.

Learning by doing.

I came across my ELD test target yesterday and for the life of me I can not remember what range I shot it at. I'm thinking 100y. Labradar for chrono. Prone, 7moh wind and 80*F ambient. Ammo was still around 70*

Best 3 shout group is hard to call, most are two in one, and #3 is .5" or more away

Love that pressure spike right out of the gate though.

Best group here is 30.8 at .7 MOA.

29.3 is 1.25 but with that SD, I am going to play with that COAL.

Pressure signs in the last two charges for both, and sticky bolt on the last. Still cycled easily by hand, just hard lift. Going to stay away from them just the same.

Spooky fast for a 130gr out of a 20" bolt gun, primers looked better than my AR fired loads, no cratering or ejector marking on the heads until the last two loads

Maybe someone with Quickload will run those charges and tell me where I am at. I still can't bring myself to buying that program.

[Sticks]

I don't think that at the pressures and velocities that we are running one needs to worry about fast barrel wear.

[Second]

You are probably right Sticks.
The discussion came up when I was trying diffrent loads with the 6,5x55 and the double based VV powders came up on the discussion.
some said a BIG No-No to the double-based powders.

But that was in a diffrent speed as you said.

Finally got time to shoot some loads with the Grendel and the 130gr ELD-M from Hornady.

Loaded up 4 different loads with 5 shots each.
Powder is VV N140.

28,5gr

Hi: 738

The average speed from this four loads feels that I have found a good node here.
The SD and ES is on the other hand quite high. Got this results on the first try also. Maybe it is the powder....?

Either way.
I have once again settled for the 28,3gr of N140. If I check the previous data with this load i have got almost the same speed so it feels that this will be a stable node.
Its the SD and ES that are too high. But maybe it will preform on target good enough for my needs.
Will continue to test jump next.

[Sticks]

Why would you settle on the worst of the 4?

28.4 to 28.5 look to be a better area.
