6.5x284 Norma Remage Build

[baconeater20]

I recently purchased a brand new Model 700 ADL 270 Win rifle to build a 6.5x284 on. I have looked at North Land Shooting Supplies Criterion Barrels as well as McGowan Barrels. Looking for 28" 1:7.5 Twist. Are these barrels pretty good? Rifle will be used just to bang steel. Really wanting to shoot the 150's or 156's out of it. What you guys think on this or to shoot those longer bullets I would need to have the barrel throated for them? Thanks

I have a few Criterion barrels, 2 in 6.5x47, and one in 6.5x284: 26" Light Palma, 1;8TW. All my Criterion barrels are nicely finished inside and out, and deliver superb accuracy and consistency. They are used with Savage and Bighorn actions, and incorporate nut and recoil lug available from Northland(James provides superb service and advice. While the 156 Berger's can be used with the 1:8 twist, for use with +150gr bulletin I order the 1:7.5TW. The 6.5x284 chambering from Northland/Criterion is a true Norma spec with a .188" throat. I should have a couple of hundred 156 Berger's arriving this week and will do load work up. Initial measurements from spec data indicate that this throat length "should" allow sufficient room to achieve 2975-3000 FPS, using slow burners like R26/Retumbo, seating to the lands, and COAL(approx. 3.3") of the cartridge to feed from my magazines. The base of the Berger 156 should extend .110" further into the case then the Berger 140 VLD which meets the exactly where the case body and shoulder meet on the Lapua brass...when seated to the lands. I'm planning to confirm/test all this over the next week or two.

Some results and rifles with Criterion barrels used for PRS/competition and Hunting, Also Criterion spec sheet for their 6.5x284 Norma chambers.

Ditto what Greyfox said, my Criterion 6.5x284 is one of the most accurate guns I have.

Another question I have is about the barrel nut in the stock. Will I have to open up the channel to fit that nut?

I used a long action Rem700 action with a 7.5 twist 26" barrel from NSS. With the nut, in a Sendero stock, I would have needed to open up the barrel channel a bit. I believe the nut was fine, but the barrel was making contact in the channel. I didn't want to modify that stock, so I bought a magpul rem700 hunter stock and it fits beautifully with no need for modification. I still may go back and open up that Sendero stock though....just like the way they look and feel.

I am also using a 700 L/A. Looking at some Stockys Stocks right now. I am going to go with a 28" 7.5 Twist. Its an ADL right now so Bottom Metal is ordered to convert it to BDL. Just was thinking of how big the Nut would be.

I built a remage with a bell and Carlson stock. I did have to modify the chamber area for the nut. The rifle was a freaking tack driver. Someone on here bought that rifle from me.
