prefit Savage barrels

[elginrunner]

Has anyone put an indicator to a prefit savage barrel such as criterion, or brux.... and determined what kind of run out these folks are achieving?

I've fired off a few emails, and havn't gotten a response back after a week of waiting.

I'm guessing most people buying pre-fit barrels are doing so because they *don't* have the facilities to put a barrel in a lathe and chamber it, much less set up an indicator on it. ???

 

[elginrunner]

After a day of no response, I gathered the same idea.

I thought that someone may have gotten one for a customer, and measured for curiosity sake. I know I sure would have. The criterion barrels would be in an inexpensive alternative to offer in a 'smith's shop. Lower cost, and shorter wait...... Just wished I knew the tolerances.

I seriously doubt that there is to many gunsmiths installing prefit barrels, when they can chamber and fit a new barrel themselves. Besides the extra profit potential, they also can assure the quality of the fit, chamber, and headspacing by doing the work themselves. Prefit barrels are a step down to precision gunsmithing in my opinion, and are not very desired either.

Pondered your original question. Why does run-out matter?

Would think the issue would be one of performance. That would be a product of headspacing, bedding and shooting tests. How it shoots, would be the issue.

Is run-out, or the lack thereof, an extremely important issue for a barrel to shoot well?

 

[elginrunner]

Ultra,
Criterion is a a sister company to Kreiger. I doubt they are turning out a bad product, however every company has production standards weither it is .0005, or 0.005 I was just curios if someone had that information.

Capt,

Runout is only important if you want the projectile coming out straight. If the chamber is cut slightly crooked the bullet will have a slight wobble to it as it comes out. At least that is my understanding of it. A more learned person may chime in to correct me if im wrong.

How a chamber is reamed has nothing to do with runout of the barrel, as mentioned above the tooling & time it would take to set up and check the barrel is more than enough reason for you not to get a fast answer. I'd roll it over my surface plate first that can be a dead give away.

UltraBR30,

"Prefit barrels are a step down to precision gunsmithing in my opinion, and are not very desired either."

So you don't believe in "switch barrels"? I think that there are plenty of shooters that are buying and using prefit barrels for everything from punching paper, varmint hunts and Competitions that would chim in here and let you know how "desired" they are.

 

[UltraBR30]

Taildrag15X - yes I believe in a switch barrel gun, when the barrels are threaded and fit to match the action and chambered by the gunsmith. Not a PREFIT universal thread job with a short reamed chamber or a nut job, that are mass produced for fast sales.

Gee! Aren't some of us bitter! Get beat by a pre-fit?

I bought a Shilen pre-fit 3 or so years ago in 243 WIN. I went this route as I could assemble my rifle myself and am not a gunsmith or a hobbyist with thousands of dollars of machine tools in my "shed."
I attached the barrel to my new Savage PTA, then reworked my used BVSS stock to fit the 3 screw action and fill in the magazine well. I head-spaces with a shiney new Lapua case followed by a matched GO and NO-GO guage set.
At christmas, Santa got me a Dog Tracker stock. I have shot in many long range BR club matches and 3 nationals.

My "cheap-ass" gun still shoots better than me after 2000 rounds. But, I have won a couple ribbons for best groups.

As far as if someone has checked for runout and such you might try one of the barrel peddlers on savageshooters it's a safe bet someone has. And as a public service, ... you may feel free to send me any of those nasty ol' prefit savage barrels, ( i like 6.5's at the moment ) and i will dispose of them for you properly. I mean the one hole groups they make are sometimes ragged, ... and nobody should stand for that. blue

 

[ttfreestyle]

for me putting a lowly prefit barrel on and headspacing it in MY gun room and then working a load up for it is part of the fun and although i am no gunsmith nor do i claim to be it is satisfying for me when it shoots 2.5 to 3.0 inch groups at 600 yards. this may not be good or desired for some but it is for me(and having my kids help is just icing on the cake).

I have a criterion barrel coming in next week along with many other goodies to rebuild a savage model 10. I'll let you know how it works out after everything is put together.

 

[Rustystud]

There are several factors to consider:

1. Quality of barrel, there is a difference in a stress releived, precision drilled, reamed, lapped, cut or buttoned barrel. The higher the quality of stock, tooling, and process the chances of a better barrel.

2. Barrels dialed in to better than .0001 and turned, threaded and chambered in one set up tend also to be a level above those set multiple stages.

You are talking about one offs with precision set-ups vs production barrels.

I can say you get what you pay for. Hummer barrels from production runs are the exception not the rule.

I ordered a krieger bbl and have a delivery date of 12-5. Now all I have to do is figure out what kind of 308 chamber reamer to get.
