8 twist 243win vs 6mm creed

[black dawg]

Looking at a tikka t3 8 twist 243. Plan is to shoot 103 or 108eldm. I do reload. I guess my question is, re barrel another t3 to 6 creed or will the 243 do the same. I understand the premium ammo availability for the 6 creed, and lack of any of the long high BC factory loaded stuff for the 243, but....?

The 243 will easily do the same. You'll burn a bit more powder, but that's about it. The real drawback to a 243 with heavier bullets has been space in an internal magbox and a factory barrel offering that was twisted right to take advantage of the heavier bullets. With Tikka offer the 1:8 twist, and you reloading, I see no reason to rebarrel until you shoot out the 243 barrel.

FWIW, I do reload, but have less and less time to do so these days. I put a 6CM barrel on my Tikka only to give me the opportunity to get quality factory ammo if I needed to in a pinch.

If they had a fast twist 243 when I rebarreled (and if I reloaded), I’d have just gone with that instead of a 6cm.

You won’t get much money back on the 243 takeoff, and you’ll pay >$500 for a new barrel. Plus you either take it to a smith or buy tools to rebarrel.

So going with 243 and loading yourself is the easy solution

 

[The Guide]

The 6CM and the 243 Win are very similar. If you stay with the 243 the case design means you will have to trim and anneal more often. 6CM means a new barrel and more cost. With an 8 twist on the 243 and the ability to get longer mags and bolt stops and hand loading you could get your chamber made to a 243 AI and then you have more horse power than a 6CM plus a better case design than the old style bottle neck 243.

If you handload, I would go with the Tikka. No downside, IMO. The Guide has a good suggestion as well if you like something a little more spicy. or 6mm Rem AI, or 6mm-284. All easy to fit on that action without a barrel swap.

You load so you can make the most out of the 8 twist Tikka and it makes sense to go that route for the easy button of a factory rifle, but rebarreling I'd go 6 creed all day and that's coming from someone that shot 243 in PRS for years and stuck with it long after the 6 creed was well established with brass and stuff. As mentioned there's less trimming with creed and it's just easier to load for and more consistent. Both will torch a throat about equally.

Definitely wouldn't replace the 243 barrel unless it needed it. Already have a couple 243s that I load for, just wanted to make sure there wasn't something I was missing.

That’s the idea. Shoot it out, then decide if you want a 6creed for fun.

Even then, you’ll be able to occasionally grab 243 takeoffs here for cheap. Obviously don’t get that privilege with a 6cm.
