Range Report Fastest barrel

[Jedi]

Barrel back from smith, just need to get melonite done now


Speed vs accuracy
If i was shooting f class or BR then i would want every bit of accuracy regardless of how slow it is, but as this is a TAK rig i will run fastest load that is MOA or better.
Shooting unknown distance speed is king IMHO
Shooting known distance then accuracy before speed, again its a TAK rig so given up 100fps + to shoot 1/4 MOA vs MOA makes lil sense to me
Flatter is better, hence the popularity of fast 6/6.5 over 308 at comps
Work smarter not harder

 

[Jedi]

Barrel out for melonite with MMI
so might be shooting it by end of month and start to post data

 

[PowerstrokeOBX]

Update? ??????

 

[Jedi]

Still waiting on MMI
should be in my hands by end of month, i hope

 

[J.A. Hamilton]

Any updates on the new barrel/coating?

 

[Jedi]

Barrel is back, Pig gun reassembled
like to thank the guys @ SAC who took care of getting it to MMI
Mark burnished the barrel and cleaned out the gunk so well its ready to shoot, running wire wool down tube is kinda weird
But with my focus on moving doubtful i will shoot it before we get relocated
Give me some time to debate replacement of razor, MSR for sure. Steiner or Kahles is the question.

 

[Jedi]

This is on back burner until we get house unpacked, per wee wench no setting up presses/shooting until everything else is done
So gonna have to wait until after new yr but i will for sure provide data asap without getting my ass beat by CINC

Sorry to hear the delay in your tests. Jedi, I just want to know, what does shooting 3023 w/123s do that 2923 will not do? I believe you said you do not shoot steel, but not sure what exactly your use is w/this carbine. You said 100fps is a HUGE deal, and that you use a 20", and in a 47, both will net lower speeds as we know vs. a longer tube and/or bigger round like a 260.

That said, I love short barrels, and one of my fave guns was a 21" M7 that spit 2878 w/120s...in 7BR. I wanted less recoil, blast, and to self spot shots. I never got hung up over 100 fps personally. I am sure you have your reasons, and just curious. I run non mags by choice, and simply allow for the extra drop, as all do and whether range or MV, it has to be allowed for, though I have hunted with handguns and understand the lower velocities needed to be effective in the field so speed is secondary to me, accuracy and shooting characteristics, as well as handling/balance are priority.

Shooting 123s at 3023 is seemingly pretty swift in a 20" in that round. Not sure if you might be above average, and whether or not a sampling of say 10 barrels would give you the same results, or if you got lucky. I have no dog in your barrel brand of choice fwiw.

I have used Krieger,bartlein,shilen and douglas. The shilen select runs almost 100fps than the others with the same reamer and similar lengths.

Are you comparing apples and apples though?

Same chamber reamer is one question!

Same lot of steel?

Are the bore and groove sizes to the same spec.? You have to measure to the 4th decimal place. Don't just say it's a .300 bore and .308 groove. That's not enough information.

I won't get into ammo/powder/bullet lots etc....

If the barrel specs. are not the same then there is nothing to compare. A difference of 100fps. from barrel to barrel even from the same manufacturer can be/is considered normal.

I will also tell you this. We make a lot of ammunition test barrels and the cut rifled barrels reference easier and produce more consistent results. That's not just me saying so. That's feed back we get from powder makers, bullet makers, ammo makers etc....

Hi Frank. The barrels in question are similar specs and use the same ammo and reamer. This has just been my experience but I do not feel like there is enough practical difference in velocity to matter to me. They all use about the same dope. There is however enough difference in concentricity, straightness and Hide support to make a difference for me. That's why the last four barrels I purchased have been Bartlein. Thanks for the great product!

Your welcome buddy and thanks for the nice comments!

Changing the bore or groove size a few tenths can have a big impact on pressures and velocity.

So Jedi, how did it turn out?

 

[Jedi]

LOL
Trust me i will provide data asap, but until house is sorted on hold

Hope to be out shooting easter/spring time frame

unpacking is going slow and i,m under wee wench orders not to unpack any of my gun gear until EVERYTHING else is done

i,m as eager to run the pig gun and see what results are as you guys are to hear them

As frank has stated numerous times this is not an apples to apples test so take info as ya see fit
just my observation of 2 barrels

barrel was setup per frank bore/groove recommendation that would more than likely yield more FPS

As i said anything that could improve fps or even rumored to was incorporated, now whether or not they work

Ya gots to wait until i get out to range

 

[PowerstrokeOBX]

Fastest barrel

I think I could order a barrel from Bartlein and get results before you ever shoot your barrel. ?

Just pokin.

 

[Jedi]

Silly me i forgot i was working to your schedule

patience grass hopper

 

[Dallas4rceMarine]

September of 2012 you said you hate waiting on barrels now, 16 months later, you are telling us patience for the results! haha

tell that woman you need to get to the range!!

PigGun

Ready to go, just need to get cabin sorted and kitchen pass

trust me i wanna get back shooting alot more than you guys want the results

 

[D_TROS]

didn't get any chrono info before melonite by chance?

Im of the camp it doesn't matter. Buy whatever barrel is available and get out there and shoot.
If it does matter, don't cut barrel so short or use a larger caliber.

Still interested to see results of the custom spec'd barrel tho!!

Regards.

[Jedi]

Sorry only data i have currently is for the broughton
Long barrels and suppressors really dont yield a usable platform, take a 24" barrel add 6-8" for can and suddenly you toting a 30" + barrel
So barrel length does matter to those of us that run suppressors, if your inclined to run a 28" barrel plus Can (34"+) press on
I wish all barrels were equal, just buy whatever and go run it. Assured that it will make x fps and last x rounds
Unfortunately thats not the case

Very interesting thread. You've got me looking forward to results jedi.

I showed Mrs. Culpeper this thread. She wants your wife's secret. I told her she should be careful what she asks for...
