New Rifle concerns

[btsmd]

Just took my new Christensen MPR 6.5 Creedmore to the range and put the first 35 rounds through it. Did the recommended break in procedure. Was shooting Winchester 129gr power points. Gun was completely erradic. Shooting from lead sled. Even had friend shoot it. Scope is NF ATACR 5x25x56. Everything seems tight. Even at 100yds it was 6+ MOA or worse. Didnt bring different ammo to try. I dont have a ton of experience with rifles but the ones I have have never acted like this. Any suggestions/thoughts? Appreciate the help.

Was all shooting done from the sled? If so, I'd suggest trying without it. You said everything "seems tight" but it may be worth starting from the ground up and doing a retourqe on everything. Also, some rifles just hate certain bullets. I have a CA mesa that's a 4-5 MOA rifle with accubonds. But when I switch to copper it becomes sub minute.

I would check the crown (muzzle) for any dings, damage, etc. I agree start from ground up, were you able to check the scope base screws? Shoot it without the sled.

I had a similar issue with a new 260 Rem several years ago. I was using some Remington Core Lok ammo. I was getting groups of 2.5" to 3" at 100 yards. After I got done breaking in the barrel and started load development, the groups dropped down to 1/2" or smaller at 100 yards. Here's what I would suggest.

1. Get some match grade ammo such as Hornady, Federal Gold Metal, Berger
2. Give the barrel another cleaning.
3. Shoot 10 rounds to foul the barrel with match ammo.
4. Now shoot some groups.

been around quite a few CA 6,5 Creeds and they all like the Hornady ELX 142 factory ammo. I would give em a try. Use the lead sled for a boat anchor.

If you don't reload, get you some Hornady Match grade ammo such as the 140 gr, shoot off a rest or bag and then report back with results. Good luck.

Shoot it without the sled.

^^^^^^^^^^^^^^^^^^ This for sure! I've never had a rifle shoot worth a darn in one of those things.

As stated above get rid of the sled, but 6"+ at 100 I've shot alot of rifles custom to factory and none have even came that close.

I've heard slot of people talk of CA's poor bedding I would look at something binding or touching the barrel.

Thanks for the input. I will try different ammo, shooting off bags and check all the bolts/screws. Hope to get out this week and will report back.

Ammo you were using isn't known for accurate loads. Change ammo and use the sled for gun cleaning or a boat anchor, as suggested.
Get a bipod

Stop cleaning it.

Sure sounds like the scope mounting screws need to be re-torqued. That might not be all the problem, but I'd start there.

A good torque wrench is a shooter's best friend.
