6x6.8 SPC Load Data

Would it be possible to get a cluster gaggle of load data for the 6mm x6.8 SPC going?

I am almost ready to just about be ready to get ready to build a 6x6.8 SPC and am very curious as to what loads work for folks:)

For the build, I am looking at a BHW 22" or 24" P3 barrel in a 1/8 to 1/9 twist rate in either a national match or bull configuration.

Thanks!

What bullet do you want to shoot? 8208 is your friend with the 6x6.8 across a range of bullets. 29.0 gr 8208 and an 87 gr vmax should net around 3000 fps. I never ended up working up a load for 58 grain pills before losing my job and selling my rifle. I'll build one again for sure 22" standard would be my choice.

After 29 the groups tightened up but its reaching max load so work up slowly.

Thank you for the information.

I would like to use bullets in the 87 grain and higher.

Here is my list:
Hornady 87g BTHP
Hornady 87g Vmax
Hornady 105g Amax
Hornady 105g BTHP
Hornady 108g ELD

I am not worried about loading out past magazine length as it is easy enough to load one at a time for paper punching..

Cheers

6x6.8

I shoot an 18" 6x6.8 and have settled on an 85gr partition load for my hunting needs.

I have found that 26.3gr of H4895 seated to 2.280 shoots just below MOA at 2,750fps (probably better, I shot from the prone off of my pack). I think it is a touch slow and could be hotter, but I have not had the time to test further.

28.0gr 8208 produced velocities a little above 2900fps, again loaded at 2.280, but I was not shooting for pinpoint accuracy, just a servicable hunting round.
