Devcon is curing now!
12% really ain't THAT much of an increase...especially with reports of Criterion's quality & accuracy being posted all over the internet.
SSSShhhhh!! Ya don't want them to think that they can jack it up more without complaint, do you??Quote:

Glad to see that your Hating Spree is over. :D
Just helped a buddy finish up his 300wm build with one of these CBI barrels. Gotta say it is pretty sweet. He was grouping 1/2MOA within 8 shots soon followed by lots of steel clanging at 650yrds. No real loaded development. 208 AMAX over 75.5gr H1000 seated to mag length. Velocity was like clock work as well. After the first ten rounds it was all very consistant at 2825 +- maybe 5fps.
Ok, Ive now shot 409 rounds through my CBI barrel so heres how its done so far.
The barrel when it arrived. It a 28" hvy 260 Rem.

The parts. The picture doesnt show the CNC machined lug I also got from Jim. It showed up a few days later. Savage 10FCP HS Presicion that I also bought from Jim.

All put together and ready to shoot: Scope is a Vortex PST 6-24x50 FFP. I love it.

The mat is the VOODOO DELUXE shooting mat/ drag bag. With this stock and a 28" barrel it barely fits. Great mat!

Here are the 1st 18 rounds I fired from the gun. I decided to start with 140gr Amax in front of 43.5gr of H4350 since thats the load I found recomended the most in all the posts I could find on the 260. I ,of course, started low at 41gr and planned to go to 44.5 but stopped at the very 1st signs of preassure, no matter how small. That was at 44.2 gr when the primer just started to develop a very slight cup. NOTE: at this point I was seating well into the lands. These test groups were shot at 200 yards.

I'm sure some the groups could have been better but I was JUST getting back into shooting after not much shooting at all in the last 16 years. But I shot A LOT before that. I was also borrowing my Buckmaster 6-18 scope off of my AR15 for this test. My vortex hadnt been ordered yet.
Anyway with it shooting this good I didnt even bother trying any other bullets or powders. I didnt want to use up barrel life looking for something better after shooting a .162 MOA group and more in the 1's and 2's after this test.
Ive now shot 409 rounds through it and the many groups ive chronographed all average 2890 fps. Again its shooting 140gr Amax with 43.4 gr of H4350 and fed 210 primers with Rem brass.
Brass- I planned on trying Rem brass and if it didnt shoot well upgrading to something else. I wish Winchester made 260 brass but they dont and I dont like having brass with the inccorect headstamp (OCD??). After shooting the groups I did I dont see any reason to spend $100.00/ 100 for Lapua when rem brass is $48.00/ 100. I plan to aneal the brass after the 3rd reload.
Just about a month later I had my Vortex scope and 10 round magazines (They use the factory savage bottom metal and are around 87.00 each from Darkeagle.com and they work great) and finally got the chance to do some 1000 yard shooting.
This is the very 1st 1000yd group I have ever shot. (when I hunted years ago my longest shot was 727yards on a prarie dog but I never even attempted 1000yd shots.)
[img width=453 height=450]http://i1083.photobucket.com/albums/j394/Rodney_Downs/Guns%20and%20Shooting/260%20Rem/1000ydG_1.jpg[/img]
The wind was calm at maybe 1 mph. Very little vertical stringing and I guess I screwed up and pulled the last shot way left. I was using my rabbit ear rear rest.
I then switched to my new "sand Sock" filled with sawdust I wanted to try out. Didnt like it at all. Here the next 1000yd group:
[img width=600 height=339]http://i1083.photobucket.com/albums/j394/Rodney_Downs/Guns%20and%20Shooting/260%20Rem/1000ydG_2.jpg[/img]
You can see the 1st group just above the target. Didnt like my new sand sock at all. just to "loose"
The next day I did some 600 yard shooting. Heres one of the groups:
[img width=580 height=450]http://i1083.photobucket.com/albums/j394/Rodney_Downs/Guns%20and%20Shooting/260%20Rem/600ydG_2.jpg[/img]
I didnt adjust for wind at all and the 1 mph wind blew me off target just a bit but I wasnt worried about bullseyes. I was looking for good groups. This one is 5/8" moa. Not bad for 600 yds.
I started running out of ammo and I realized I was down to 3 rounds left so I headed back to the 1000yd range to shoot the last 3 shots.
ALL of the targets in this post were shot using a Harris Bipod except the very 1st test which was off of a rest.
Here are the last three shots I fired at 1000 yards. I borrowed my buddy Clints sand sock on this 2nd day and it worked a lot better than mine.
[img width=600 height=250]http://i1083.photobucket.com/albums/j394/Rodney_Downs/Guns%20and%20Shooting/260%20Rem/1000ydG_4.jpg[/img]
I started coloring my bullets with different color permanent markers so I could tell exactly which order the shots were fired in. A different color for each bullet.
2 1/8" 3 shot group @ 1000yards!!! I was bummed I didnt have 2 more rounds to shoot. Note the conditions were pretty much perfect when I shot this.
Since then a friend and I now have a spot to shoot 1000 yds (target is actualy 1010yds from where we set up our shooting bench.) Heres a few picks of the target and a few groups I shot the 1st time out there. The wind was quite gusty so the shooting was tough.
[img width=600 height=314]http://i1083.photobucket.com/albums/j394/Rodney_Downs/Guns%20and%20Shooting/260%20Rem/1kcollection.jpg[/img]
Alan is in the picture shooting his 6.5x47( In case your wondering why that gun doesnt look like my savage ;) ). I took the pics to show where the target was. The groups are mine though and thats me walking up to the target. The 1st groups measured 7 1/8" (less than 3/4" MOA), the 2nd was 9 3/4" (just under 1 MOA).
[img width=600 height=314]http://i1083.photobucket.com/albums/j394/Rodney_Downs/Guns%20and%20Shooting/260%20Rem/1kcollection2.jpg[/img]
These pics show the target at 1x, again at 4x, and me walking up to the target board. And two of the groups I shot. wind was gusty and 8-10 mph on the 1st target, 10-13mph on the 2nd. The notes on the target should say Savage FCP , not FPC.
Cleaning- When I 1st shot it it took a lot of patches and several times through with a bronze brush to get all the copper out. After 100-150 rounds even though I still see what to me looks like a lot of copper build up and the 1st Bore tech eliminator soaked patches come out DARK blue. I soak it in Bore Tech Eliminator with 2-3 patches, then run a bronze brush back and forth about 10-15 times, a few clean patches, soak it again and give it a few minutes then run a few more clean patches and its spotless.
OK, so there you have it. I love my CBI barrel.

Great report. Love the details and the view of the open country. I may have to move somewhere out there to strech my savage's out a little.
Just an update, Brenda shipped another 21 barrels with UPS last night. She calls everybody with the news about their orders so if you did not get "The Call" yet your order has not shipped. Criterion is back logged on certain calibers because the reamers have been very slow in arriving. The 20 Vartarg and the short throat 204 Ruger being the last to show up. The 22-250 AI, 6.5X55 Swede and the short throat 284 Winchester are due in any day now and we can get caught up on a few of the delayed orders.
For those of you that missed the pricing change notice, Criterion pricing will change effective September 1st.

Thank you for the call Brenda! Thank you Jim!
Just received my call. Can't wait til Monday!
Thought I'd post my results. Sorry no pics for now.
28" 260 rem bull barrel 1:8. 100gr NBT 3400+fps. One ragged hole.
120AMAX again 1 ragged hole at 3003fps avg. I have more to go but why raise pressure if you don't have to?
140AMAXs were terrible with 4350. velocity was 2720-2790. Gonna retry and increase charge and also dump some 4831 and see if it tightens up.
140BTHP from hornady were also bad. I have ogive issues with these and need to call them for replacement.
When I say bad and terrible I am talking a little over 1.25".
I am completely satisfied with this barrel and plan on adding a 223 1:8 in the future or punch it 22-204:)
got two ;)
Today I did break in on my new CBI barrel, I got 2 barrels from Jim, one in 6BR 30" bull and 26" varmint in 260, today I tested 6BR. Basically I did one shot clean for 5 shots, then fired 25 rounds without cleaning it. I load 30 rounds using 100 gr Hornady Interlocks, 105 gr A-Max, 87 gr V-Max also I had 105 gr Barnes Match Burners. With V-max I did one shot clean, then I fired Barnes MB:
[img width=508 height=450]http://img851.imageshack.us/img851/9089/cbi6mmnorma6.jpg[/img]
then A-Max:
[img width=478 height=450]http://img692.imageshack.us/img692/5479/cbi6mmnorma7.jpg[/img]
and I finished with Interlocks, they gave biggest fliers, but they are not match bullets.
[img width=526 height=450]http://img217.imageshack.us/img217/6447/cbi6mmnorma8.jpg[/img]
and another group using Interlocks
[img width=472 height=450]http://img199.imageshack.us/img199/3241/cbi6mmnorma9.jpg[/img]
after firing all those groups without cleaning the barrel it had just little copper embedded
[img width=477 height=450]http://img199.imageshack.us/img199/1918/cbi6mmnorma5.jpg[/img]
it only took 4 passes with KG-2 and a patch to clean all out:

Thanks again Jim!
Just got off the phone with Criterion. To anyone who is interested, they have received the new 6.5x55 reamer with a more traditional throat. Neal @ Criterion said they just chambered and muzzle threaded my barrel today and it will go out on Monday to Jim @ NSS. I can't wait! I'll be sending it off to be Nitrided if everything looks good with the barrel.
Regards,
-Dan
I didn't even know they chambered for the swede. What throating options do they have available?Quote:

I have a 24" heavy mag contour ss 260 Ack. barrel on it's way.. on week 9 and counting! It's so hard being patient. I'm literally going to be like a kid on xmas when that thing arrives.
So any of you guys running the polished barrels or you sanding them with 3M scotch brite pads.
I attached a Scotch brite (red one) to a rotary sander and matted mine. Looks nice.Quote:

Rocca,
That's what I'm talking about, looks real good. Thanks for the pics.
