Your barrel is fine...if your getting those groups out of it, I would be hard pressed to rid myself of that rifle.
Then again, if it's a 'sell one to fund the other' type thing...well....you have to do what you have to do!
I am NOT brand loyal, I have more Remington stuff than any other, BUT.... it is all older Remington.
We have seen sales of the CDL become almost non-existent at both shops, and have sent quite a few Remington rifles and shotguns(870 mainly) back for warranty work.
The CDL is a wonderful looking rifle and it sports a 24" barrel, which I prefer; but I have to say that the cost of this unit is way more than it is worth, and the accuracy is NOT going to be there, unless your lucky.
About the only thing the CDL has going for it is its nice stock...and the bluing job Remington is turning out on this model is good also.
I hear more and more from the buying customers around here that the Winchester 70's we have sold them are great. The two I have shot were excellent...accuracy was not phenomenal, but was around 1"@100y...which, to me...IS phenomenal! lol
I never was a Winchester man...but we all can change with a little help! lol
