SU: Have you used the 130 Swift on game? I am sort of getting an itch for one of these things....
The 280 Remington is overbore.
The 7 Rem Mag is over bore.

. With a 1:8.5 you can easily find best results at 3100-3150. I don't know why, but this seems to be the case. Listen to Dennis, he KNOWs what he's talking about.

SU: Have you used the 130 Swift on game? Hi Bob, yes indeed I have killed with the 130 Swift. A big 300 lb mule deer at 520 yards using a 260 which I later punched out to 6.5x284 and picked up another 150 fps +.

SU: Neat! I think I want to build one of these things. President of my club and another freind were part of a team that did very well at Wimbledon this year. They were all shooting 6.5/284,and said the accuracy is unreal at 1000.I am kind of enchanted with the whole notion.Time to start looking for an action,and order a barrel...
I am leaning Kreiger or Bartlein 8-twist....

Ok guys I've narrowed it down to these choices as per twist and maker, either it's gonna be a 1-8 or 8.5 twist Broughton OR a 1-8.2 ROCK creek. Like I mentioned above I'm looking at shooting 120grn BarnesTSX, 130grn NoslerAccubond, and POSSIBLY 140grn Sierra and Berger 140 grn VLD.....................so I take it most would go with the Broughton???

Excellent info, Dennis.. Thanks.. I was not aware of the 8.5 twist info re: accuracy on the 6.5-284.. Now, if I can just remember it for more than an hour..

I have 1 broughton and love it but have never had a bad Krieger. as far as the bullets you list if you find a load that works great with the Berger 140grVLD it would only waste barrel life messing around with the others.

I figured as much boat............ ? Those of you that have a Brougton 6.5x284 would it be safe to say the barrel life would make it to lets say 2000rds??? I know Tim won't pull my leg be he say one could EASILY get 1800-2000+ out of HIS barrel while others say 900-1500...

I think anybody--including the barrel maker--who makes an estimate on the number of rounds you are going to get out of a barrel is making a WAG. There are just too many variables, such as how rapidly someone shoots and the kind of cleaning regimen they use. A 10,000 round per year target shooter who goes through several barrels a year may be able to see brand-based differences, the rest of us likely never will.

I agree... I like to hear estimates especially out of a throat burner like this, just to give me some type of idea on what I'm working with.

And see, I can't figure out why it should be that much of a throat burner. It is burning mid 50s grains of powder--just like the 25-06 below it, or the 270 above it. I have a completely unsubstantiated hunch that the rapid strings that the target shooters run have as much to do with the short barrel life reputation as anything else.
Kinda like John Barsness's experience with the .264 Win--if shot slowly and carefully, it's barrel burner reputation is overstated. But you can also burn one up in an afternoon in a PD town if you choose.

With me at the bench, as in zeroing in for the hunt or load development with the the fan blowing on the barrel(keeping it cool), and shooting in 3-5min. intervals I can't see why this cartridge will burn a throat out. And to say the least basically ALL the info. as per barrel life have came from target shooters that's why I'm asking questions here.

A 6.5x284 shooting 140 grain bullets will NOT likely give you 2000 rounds of service. Sorry, that's just the way it is. You can get 1000-1200 and then you are going to want to set the barrel back and rechamber to get a clean throat. I am strictly going by competition standard as this chambering is by far and away a competition caliber over a hunting caliber.
If you don't mind a 1/4" degradation in accuracy after 1200 or so rounds you may get 2000. Your best accuracy will be gone by 1200 or so. There are a million guys out there shooting this in F-class, match and 1000 yd BR so there is a lot of a data on this!

I ordered a barrel from Tim North and he had exactly what I wanted in stock. #4 contour 8 1/2 twist. This is the prefered twist right now. It "hot-rods" a little better than the 1:8. With a 1:8 twist (I used to shoot 1000yd BR) you would ALMOST always see best accuracy at 3000-3050 fps. With a 1:8.5 you can easily find best results at 3100-3150. I don't know why, but this seems to be the case. If you build a 6.5-06 imp the 8.5 twist is even more important.
The 1:8.5 will easily stabilize the 142 SMK and the 140 Berger VLD. I mostly use the 130 Normas these days. Hope this helps Dennis it will be a Broughton in 8 twist Tim said he/they didn't make a 8.5 twist, so I went with what he builds...
