243 to 6mm creedmoor

[Matt Craig]

What would have to be done to do this conversion on a tikka t3x? Would it be a huge hassle? I ask due to the barrel being the same. Or would i be better off buying a new barrel?

It would be easier to rebarrel. Otherwise you'd have to cut off some of the barrel from the chamber end then have it reamed to a 6mm creed as a 6 creed is shorter than a 243.

That's what i was thinking but wanted some input. thanks for the feedback. It's appreciated

May I ask why you want to switch from a 243?

 

[Matt Craig]

Just to do something a little different, thought about buying one factory made but prefer Tikkas or Sakos to anything else. I only use my rifles to hunt and plink around. Don't need to convert it as i know there is no real difference when it comes to hunting whitetail. Its just something to do.

I agree, i would rebarrel. They are both great cartridges. i'm not sure what the 6mm Creed would do that the 243 can't?

I'm no expert; talk to a gun builder. I'm having a new Remington 700 in .243 re-chambered in .243 AI. Cutting, re-threading, and re-chambering the factory barrel is costing me less than half the price of a new match barrel. I'll rebarrel when I shoot the factory barrel out ... and then decide if I want to do another .243 AI or switch to 6mm CM.

Re-barrel would definitely be easier for a Smith to do. I don't know what your current twist rate is but, if considering going to a Creedmoor, I would definitely look at the 7 and 8 twist rates to take advantage of the heavier/higher bc bullets.

If u take a standard twist 243 and use the same barrel for a 6mm creed your twist rate will be too slow for the a lot of the loaded ammo.

I wouldn't rechamber a .243 to a 6mm Creedmoor. Twist too slow if you are going to shoot factory ammo. Already looked into it myself. I'm going with a new 7.5 twist barrel.

Just buy my Remington 700 in 6 Creedmoor. It's a turn key package less the scope. Ready to go.
