6.8 spc load data

[gunjunky]

Looking for some nosler data on the 6.8 spc and 110 AccuBond. I noticed no data on the Nosler website.

I can't speak to Nosler data, but you could start with the start charges for the 110gr VMax from Hodgdon's site (data.hodgdon.com) and work up carefully.

I use alot of Hodgdon's online data as well. Great stuff to work with to get you started.

What platform are you shooting the 6.8 in? Scotty

There are at least 3 different chamber specs for the 6.8, and I'm not sure which one quickload has, so I'm hesitant to post an QL data for that particular cartridge.

Scotty,

I have a saami chamber 1-10 twist 16" barrel. It seems to do well with the Hornaday vmax
factory loads.

Barnes had some data on their web page. So does Ramshot. Go to the 6.8 forum, lots of loading data their as well as ARFCOM

This is where I would start.
I can't guarentee this is for a Spec1 chamber, so work up carefully.

I did some load testing with the 110AB and had some success with both RL10 and H322 but the loads at AR-15 COL were VERY compressed. I eventually went to the 100gr AB.

There is a ton of load data and info here....
