Christensen CA 10 6.5 Creedmoor

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

Much easier to shoot with only one recoil impulse eh Greg.

What do the five shot groups look like?

I find the trigger position troublesome as well....

What's your target made out of, painted board?
I don't think I've ever seen you with a picture of a paper target.
The recoil impulse is interesting, never thought about that.

I have a Joinery Factory at my finger tips with endless Melamine off cuts for my target holder :)

Paper targets are very average when pined onto or target backers at the range, especially when damp...

Card is much better but $$$ compared to off cuts with the amount I go through.

Fair enough.
If the backer is wet I put the paper target in a samwich bag.

Yep,

You get three with a gas gun :thumbsup:

One when you fire, one when the bolt group pushes the buffer into your shoulder and the final one when the bolt locks home again....:cool:

Not much of a problem on the AR 15, their BCG is so much smaller & lighter, even with the gas turned down nicely the big one moves the platform heaps.

The lighter weight of the CA 10 won't be helping much.

All I hear is complain complain!!!Any one who doesn't like a gas gun in creedmoor have no taste.

I took it up the range last night, got a little dark for the Oehler so no velocities :(

Looking pretty good, now I just need to duplicate it & get some velocities tomorrow :)

Your bullet has not stabilised at a 100 yard , it is fishtailing a bit ;-)
