In your opinion and in your experience, for those of you who have experience with both, which cartridge is more accurate, and which would you choose: the .243 Winchester or the 6mm Remington? I was shooting my .244 (6mm Remington) today and was amazed at how accurate it is. But then I recalled a .243 I had years ago which I believe was even more accurate, though in the long run it may be a toss up. My .244 is one of the old Rem. Model 722's w/ the 1 in 12 twist that has been custom stocked and the trigger reworked to be extremely light. It will put a 90 grain bullet into 1/4" all day long and will shoot a 100 grain semi spitzer almost as well. 75 and 80 grain bullets shoot 1/2"or less but POI will change very noticably when switching from one weigth to another.
The .243 I had years ago was a Rem. 788 that would group anything I shot through it into 1/2", but the POI would not change, or change very little to be of any significance. I really love the .244/6mm, but if I had to choose between the two, based on availability alone, I would choose the .243, but, being a handloader and because of all of the older guns available, I would choose the 6mm. I guess there is really no advantage of one over the other.

| I was in a similar quest awhile ago. I purchased a new take off .243 barrel and it has proven to be accurate with two bullet weights. 55s nosler varmegedons and 95 bergers. Beings i wanted it for coyotes and antelope this works out perfectly. There is little real world difference between the two calibers. I believe either is a fine choice. |

| Loaded single shot the advantage goes to the .244/ 6 mm with the longer neck. Loaded to a magazine length of 2.80 to 2.86" the advantage goes to the .243 Win as you are able to push the bullet out to the lands before exceeding the magazine length. |

| I believe the 6mm/244 has a bit more case capacity than the 243 and can reach a little higher velocity. That said, they are very close. I have a 243 but I'd sure like to try another 6mm. I've owned three 243's and two 6mm's. The 243's were more accurate but I'd still like to try another 6mm. A friend has one of the old Remington 700 Varmints in 6mm and it sticks 75 grain Sierras one on top of the other. My 243's were 3/4 inch rifles at best. Still they had standard weight barrels and my friends 6mm has the heavy barrel. |

| If this is primarily an accuracy quest, I'm curious if you might also be looking at the 6mm Norma BR or one of it's half sisters, the XC or Dasher? |
I'll bet ya a hundred and five thousand dollars you go to sleep before I do.

| A lot of good points made here.I chose a 243 because you have more choice in brass,and better brass.The 6mm has a longer neck and a little more case capacity,both of which are good for the reloader.Both can be very accurate.Fred made a good suggestion,and I will probably go 6mm br when my 243 barrel quits shooting.Let us know what you choose and how it does.
