The barrel is a HART 6.5/284 with about 1500 rounds down. It is past it performance peak, but was an amazingly accurate barrel. It is 27" in length and a Remington Varmit contour without flutes.

The question is would you cut it back to 22" - 24" and rechamber to a 6.5 BR or .260 Rem? Or just buy a new barrel and start fresh...

Define the expectations of your next project. If you are after a hunting gun it will be fine. With a 260 ir 6.5x47 you can set it back far enough cleaning up the throat and making a nice deer puncher. If you want a new long range bench gun, come up with the bucks. Nothing is cheap about high performance.

Can you take a 1/4"-1/2" off the shank end to clean up the throat?

I generally see that the throat wear is the the biggest reason for accuracy loss in older barrels.

Frank, I am sure that I could, but I just want to play with a different cartridge for a while.

30/378, Yes you are quite right about the expense of high performance... It was more than worth it!

I'd borescope the barrel throat area....and forward.

The barrel may have more wear, down the bore, than a person would think. Especially with a 284 case based cartridge.

Just my $0.02.

That barrel would be perfect to cut 4" off the chamber end and contour for an AR15. Chamber it in 6.5 Grendel. I've built a couple off of shot out high power barrels (Krieger) and they've all shot fantastic (sub 1/2MOA). If you don't think you'll be using that barrel for anything, PM me and I just might take it off your hands.

Matt, I'd not mind shooting a 6.5 Grendel either... appreciate that thought.

My barrel is 1" longer than yours but added flutes still a heavy rifle. I'm about at the end of my 6.5x284 and I'm going to toss the barrel. If I was going to do anything I'd have it rebored do a nice 284.

That's what I did with a shot out 257 Roberts barrel, a heavy one that had enough to rebore and chamber in a 284 Win. Gotta love that chambering. Mine is on a 98 action.

yep on the rebore, go to 7 or 30 cal.
30x284 is easy enough of a reamer to get.
and would clean everything up with a minimal amount taken off the chamber.

Good suggestion!!!
Not much mention of going upwards in bore size when discussing 284 derivatives. It's always a 6x284, 25x284 or a 6.5x284. But, I gotta think a 30x284 would be awesome, and do it on a short action too.. LOTS of great 30 caliber bullets to select from..
I'm in that "short action" stage of life...

So who is THE rebore man to go to? That 30/284 sounds like a winner.

Here is one http://www.cutrifle.com/

Gotta remember! The 284 case is basically a mag case with a rebated rim! Thus you`ll have to cut at least 1.800 off the breech to get rid of the 284 chamber to go to a smaller [BR or 260] case. I know of a guy in the Dakotas that does real good reboring/rifling but it isn`t cheap--about 175.00 I believe. If itm were me! I would opt for cutting off both ends enough to make a BR or ?. You figure the cost of reboring/rifling, the shipping etc and you got the best part of 200.00 tied up in a barrel. Even Dick Nickel inhis best days wouldn`t positively guarantee the accuracy of a rebore although I never had one of his that DIDN`T shoot VERY well. Same with Norm in S. Dakota. The only time I REALLY look at the rebore is if, like an old Mauser African rifle I have that was in 8X57 and horribly shot out, it has the old style octagonal/round contour with the engraving etc. I had Norm bore/rifle it out to 9.3 ,did a neck throat job here and had an engraver in WA make the 8 into a 9.3. Beautiful job by both parties and it shoots great. Hard to tell it`s not an original 9.7X57. Heck! Shorten the barrel and make a 6.5BR. Lots of fun there.
Aloha, Mark

If you have a long action why not just rechamber to .264 win mag ?
I don't know if the dimensions work, but i would expect them too.

I would use a new barrel on your primary rifle and whack the chamber off and put the old barrel on another project rifle for some other use.

35-284?
