@2005ailes - the problem is people don't read or pay attention.
You never mentioned hunting and you said "target rifle with a few competitions".
The logical answer is a new 223 barrel - 24 or 26" M24 contour in a 1/7" twist. 223 or 223 ackley if you reload.
Most of the time when someone asks about a rifle or cartridge folks state "at a 1000 yards" blah blah blah.
Well, how often do you ACTUALLY shoot at a 1000?
So, just target shooting for enjoyment the 223 has distinct advantages over the 6.5 creed = less recoil, less blast, less cost per round which in turn equals more shooting.
It has been said many times that PRS comps are won inside of 800 yards - so a fast twist heavy 223 bullet can be competitive.
Again, this is my opinion - and none of us matter - it's your money, your gun, and your fun.
@Southern Custom your statement about getting the Remington close to the performance of a factory Bergara simply isn't true. He already has his rifle in a KRG stock, he didn't mention trigger which the factory Bergara trigger is not amazing. Your opinion is they are "fantastic", but again to you. I'm sure it's better than the Xmark pro, but the guy didn't mention his trigger. Also, it's well documented on the net that Bergara rifles are not without flaws and issues.
$700 for a Bartlien or similar quality barrel on his existing rifle puts his rifle ahead of any Bergara HMR and probably ahead of any factory rifle. If that wasn't true people would not be replacing factory tubes with custom tubes.
Now if he were starting from scratch and looking at a factory Remington vs factory Bergara...
