It's TRUE! It all depends on your goals. I believe Elmer Keith said, "Efficiency be danged, its results we're after.The old, OLD, .243 Win and Ackley's, ARE,.. Sexy and, "serious",.. "Barrel Burners" !
The 6xc, will get most shooters, 2,000 to 2,500 rounds of,.. Bbl LIFE !
I’m building a 6 Creedmoor with a 7.5 twist. What powder you usingI have a 6CM.w. 24" 1:7.5" twist, and my main load is a 105 Hyb @ 3184fps.
Since I have not been able to find the 105 Hyb in months, I recently worked up a good load w. 115 VLDs @ 3087fps. I shot it this past weekend out to 1386 on steel with fantastic results.
A .243Win would duplicate these results.
If you are already set up for the .243, no reason not to chamber up a rifle in that cartridge, expect maybe quality brass availability. Lapua makes brass in .243Win, but that is about the only top end brass available. The 6CM has SRP or LRP available from Lapua, Petersons, and Alpha
Thanks for the responses, I ordered 243 ai dies last night, so I'm going with that at this time. Doing research now on the chamber, how much free bore needed. Leaning toward the berger 105 or 108 extreme hunters. But might use up to 115's.He said 243ai, that is far sexier than a Creedmoor of any flavor.
