Scott my vote goes to a 243. John Benjamin that builds my barrels (from scratch) use to shoot for the Army Marksmanship Unit. He is big into the AR-10. John shoots the 243 in competition. However he does like the 6X47 Lapua which I shoot, and the Creedmoor. Everyone has jumped on the Creedmoor band wagon because it gets so much press from the PRS competitors. The last time I was at his shop I saw a barrel laying there that was purple with sparkles on it. I commented on it and he laughed. He said at the matches guys talk about all the latest and greatest calibers so he sprayed his 243 barrel purple and beat them all. BTW the top bolt gun guys at the PRS are now using the 6BR or a variation of it. As Benjamin’s said, “the 243 it just works”. That being said he has tried to get the 6BR the feed in the AR. The last I heard it ain’t working.

Here is a setup that started out as a tubegun from Eliseo. Benjamin did some modifications to it. It is a 223 and 300 Blackout switch barrel. Notice the tube in the middle of the first picture. It is a supppresor that he made. If you can see them there are flats on the barrels for spinning them off.
One another note He has a suppressor design for the AR that is a hand guard that is 8” longer than the barrel. It is a pretty slick setup. He started out to build a flash hider for a sniper rifle going to the Middle East, but found it works really well as a suppressor. Yep the setup is legal with a serial number and all.

+1 Gabriel. I have a 243 and also the 6.5 creedmoor. So far the 243 will out shoot the creedmoor anytime. Still trying to find a load the 6.5 likes. The 243 just shot good what I fed it. Haven't shot it at paper for a while but it will sure whack a coyote!
GOD BLESS. Dean

What twist and length barrel was used for these AR based 243 rifles?

Another thing to look at

If you don’t go the route of the 300 Blackout.

Subsonic 308

My 243 is 1/10 twist in a 22 inch barrel. Check out alex pro firearms. That's where I got mine, the ones they show now are quite a bit cheaper than when I bought a couple years ago. Guess they are a little different set up than mine was too. But real happy with the alex pro.
I got my 6.5 creedmoor from cbc industries and have had lots of problems with it so far. Feeding, scratching the necks of brass on extraction. Haven't found a load that works yet. Holes blown in primers when still loaded a couple grains below max, the list goes on. Wish I'd got the 6.5 from alex pro also, just didn't want to spend that much more. Rant off.
GOD BLESS. Dean

Pretty sure he needs a 45 Raptor.

243

I worked as a Wildlife Officer for 32 years. For some reason I kept a record of the rifles used by the "best" poachers I arrested. The 243 in all makes were the rifle of choice for 70 percent of poachers. I have seen some miracles shots with this caliber, great distances, running targets and quick kills. White-tailed deer, fox, bobcat and feral cats. Mine is a Remington 742. Just thought this was interesting. I have been retired 34 years, grandson using rifle.

You must have the DNA for your mother's mind reading ability. Yours enhanced by the ability for viewing over great distances.

.45 Raptor does look interesting. Just the ticket for flock shooting big game in Wyoming.

The Raptor would feel mighty comforting in grizzly country while elk hunting for sure
