I put a 20" Proof Research 6.5 Creedmoor barrel in my Christensen CA10.
It weighs 4.955 kgs 10.92 Lbs with the DPT suppressor.
I had to get an .875 adjustable gas block for it.
Pretty earlier into load development to be fair, but it's showing plenty of promise for a gas gun
Seems to like the Berger 130 AR Hybrid.
The Hornady 147 ELDM is showing promise, it didn't like the 143 ELDX.....yes the pic is wrong, Sunday arvo blues
The 147 has the ballistic & terminal performance edge so I will try tuning the load a bit more, I find it much easier shooting a Bolt rather than a Gas gun
