I'd like to see how your .223 Criterion's shoot and what heavy for caliber projectiles you are able to mag feed. I've got a savage action just begging for a new barrel, chassis and trigger......well Padom? Have you spun them up yet?
I’ve been researching the tl3 for my next build and just came across this thread. Really looking forward to the longer range testing!
Not gonna lie, Im rather disappointed to see the test not being carried out with the same barrel nut for each barrel. I doubt there will be a difference but all making a constant a variable introduces inequitability. Or at least test it on the established mullerworks to see if it changes anything before moving onto the criterion. Unless youve changed it before that I didnt notice in which case w/e.
So I talked to Aaron over at Bighorn today. He said yes and no on what NSS said about headspacing. As mentioned above, do not insert a headspace gauge and close the bolt, it will cause damage. You need to put the headspace gauge under the extractor and guide it into the chamber.
A number of us have been using CBI barrels in F-class for several years now, and due to the success more are jumping onto the bandwagon. Some are using Savage actions, myself and friends are using Stiller with the Remage setup because of the increased availability of aftermarket parts. We win matches and have held national records using rifles that are less than half the cost of the customs we compete against.
I don't know why someone trusts the barrel maker to make the barrel, but then questions their ability to spin the chamber ????? What nonsense. Using a borescope the chambers from CBI have been flawless. For the upcoming 2018 season I'm contemplating switching from a CBI 8twist Rem Match Chamber (using 80.5FB) to a 6.5twist ISSF chamber to run the 90gr Berger for longer range Ftr.
Sorry yea that's supposed to be .01" off the lands. I will correct the the targets. Coal is 2.51", lands are 2.52".. I am doing the same workup for all the barrels..the shilen was seeing pressure at 25g so that's where my testing stops. This Criterion had no pressure at 25g fyi.
I have Hornady latest 10th Edition which lists the 75 ELD and 80 ELD (and Amax's) and they also list coal 2.390" but list max Varget charge for 75 ELD of 24.6g...Ive seen pressure at 24.8 and higher with the other barrels but not this Criterion..
Also reviewing my Nosler Reloading book #8 (latest) they have a max Varget charge of 24g for 75 and 80's...
I do see my Lyman lists 75 and 80g at 25.6 and 25.0. I had pressure at those numbers with the first 2 barrels. I mean I'm getting 2900's and 3000 fps numbers as well with the 2 powders I'm using which beat the numbers Lyman is showing (2843) with 25.6g....
Remember, manuals are for safe starting points. Work up and test accordingly. Every barrel is different.
I used the same.nut for all barrels. NSS barrel nut. Not I take the barrel action out of the chassis by removing the 2 action bolts.
Thanks, Padom, this is a great thread. I pre-ordered a Bighorn Origin and I'm following this thread closely. I have a Savage that i've swapped the barrel on before (Shilen and Criterion -- the Criterion has been great), and if there isn't a material difference in accuracy, compared to the wait times of a chambered barrel, I may do the pre-fit route on the Origin too.Kreiger called today and they are sending a barrel. That barrel will be spun up by Keystone Accuracy for this review.
Excellent. I have an email out to Bighorn as well about action wrenches. I have a Wheeler action wrench that works fine with the Savage, but I'm hoping the Bighorn Origin can use it as well (has pinned scope rail -- not sure if that means I can still unscrew and remove the rail to clamp on the action wrench or not, and something about a mechanical ejector?). If the Wheeler doesn't work, looks like I'll have to buy their rear-entry action wrench and give that a try.Shouldered. but there is no difference. you can see his button barrel in the other review thread I started last week for 6.5x47L. the nut vs shoulder makes zero difference in accuracy I can assure you of that. I'm far enough along into this review to say that with 100% certainty.
Ok, thanks for the info that I definitely need their rear-entry wrench. Looks like I'll add that to my order with them. Thanks again, this is a great thread. I'll have to talk to Southern Precision then on either a Bartlein or Mullerworks pre-fit. The Mullerworks you shot a few pages ago -- WOW!You don't need to remove scope base. I've never had to remove them on my TL3. You need bighorn wrench due to mechanical ejector.
This statement will cause so much butthurt across the Internet!Shouldered. but there is no difference... ...the nut vs shoulder makes zero difference in accuracy I can assure you of that. I'm far enough along into this review to say that with 100% certainty.
