Is it worth replacing my 243 with 6mm cm

If your 243 is still a good shooter and had barrel life maybe not worth, the 243 will do most of what the cm will except the longer bullets but the 243 has more in the gas tank for the 105s and down. But we'll we all would like a new rifle lol, what's your 243 and what would you replace it with and the use for it.

Only if you want to sling the high BC 6mm bullets.

If you're fine with the </=100gr hunting bullets, I wouldn't bother.

If I were buying a new rifle and had to pick between the 2 I'd take the 6mm CM every time. If I had a 243 that I liked it would be a tough choice. It's not just bullet weight, but bullet length. A 100 gr hunting bullet will be a lot shorter than a 100 gr high BC target bullet. The longer target bullets won't stabilize as well in barrels made for hunting bullets. And the extra length may not fit in a 243 magazine.

If you use it primarily as a hunting rifle the 6mm CM doesn't offer any advantage. But there are no negatives to having it either. That's why I'd choose it if I didn't already have a 243.

What will you use it for?

I'd be afraid my many 243 and 308 shooting buddies might make fun of me. lol

If the 243 is still shooting ok I wouldn't swap. Like the others have said, it depends on what you have and what you want to do with it. For what its worth, a few years ago I caught the 6m bug and researched them. I ended up building a 243 with a 1-8 twist barrel. The 6 CM was not on the scene at that time. Neither were some of the other hot 6mm's.

The 243win and 243AI were my favorite cartridge for almost 20 years, but I spent all of that time spending money on custom reamers, dies, and barrels to make it behave like a 6 creed does out of the box. When the 6.5 creed came around, “mildcatting” the 6 creed became too easy - smiths all over had reamers on hand, drop in barrels became readily available, dies ready on the shelf (6.5 creed Redding dies with .267-269” bushings), brass readily available without fireforming - all upside.

Most folks who are happy in their application with a 243win won’t be blown away by converting to a 6 creed. But there are specific aspects of the 6 creed which improve upon the 243win which make the upgrade sensible for a lot of us.

I rarely "replace" a rifle, but rather just add another one to the litter.

I have a couple of 243s, a 6mm Rem, and a 240 Weatherby Mag. The 240 is a screamer if you like speed, but the others are great too. All will kill varmits up to deer sized game without issue here in Texas.

I’d get the 6mm Creedmoor if it were me
