6mm Creedmoor- sooty case head

[Scotch_egg]

Is anyone running a 6mm Creedmoor?

I want to use 87gr V-max 

load data is limited. I used Viht start data and got sooty case heads with N150 and groups were crap. With a max 38gr

I have just ran the powder through p-max and I am tempted to start again with the N150 but use this data which is lot more powder! 
 

I am using Lapua brass at 50.9gr water capacity.

20” barrel

Is anyone using N150? 
 

I also have RS62 on hand.

Hi,

I have a 6.5 Creedmoor. And I use Viht N150 and 130 grain Sierra TMK bullets, with Lapua brass. And I get great results!

Including with Viht N150 and Lapua 130 grain OTM bullets. I'll see what quick load see's.

Cheers.

Chaz.

I popped it on the Hide and some one has ran it through for me. 
 

looks like the Viht data is total junk. The operating pressure is dangerously low with their data. 
 

I should be starting at 40gr

There’s a few powders similar ish to n150/ 550 ie the win760 and the 4350 . So possibly 41 to 45 area  , starting low etc  .

Hope it’s useful
