You do realize that you can get a good barrel from both manufacturers right? QC should be a little better with Proof, Shaw is probably button rifled vs cut rifling with Proof. But I got a bear creek barrel that shoots just as well with almost no POI shift between ammo. I got lucky, you got something that was basically guaranteed to be quality with the proof research barrel, and if you sell your upper, that Proof Research barreled upper will be worth more. My bear creek is worth 300.00 on a great day regardless how well it shoots. But you won't always be able to tell the difference just by shooting them.
Actually, all this information is covered in the video! At 09:36 I mention how the Shaw, which is button-rifled, outshot Proof, which is cut-rifled and lapped. The last 1/4 of the video is discussing how when you spend more money on a barrel, you're buying quality not performance - and performance isn't going to scale w/ cost. (At 17:19 I show how my current Shaw barrel is actually a replacement - the one I originally ordered had chatter marks that affected accuracy.)
I have no evidence or experience to be able to rightly explain this, and I only two people that own suppressors. I am told, however, that the answer is yes - but it takes an absurd amount of time and firings to get there. And that's assuming gross negligence as well. Like, we're talking potentially years.
Try some Berger 90 grain target boat tail hollow point bullets (tangent ogive not vld)with Hodgdon Leverevolution at or near max charge . A seating depth of 2.260” oal and you’ll have some excellent results.
With the Proof Barrel? Nope. However, something I've been doing in the background of all these videos is some upper receiver testing, and I do have a BCM upper which you have to thermal-fit barrels into. I also have a standard upper, and the Aero Precision Enhanced upper, which is a semi-monolithic design. Currently, I am of the opinion that the upper receiver largely does not affect accuracy - as long as the upper is of within-spec quality. Rather, I should say, if it does affect accuracy it takes a backseat in comparison, and in relation, to other factors. Either way, simply thermal-fitting a barrel into a platform will not automatically make it more accurate. I base my opinions on my testing and experiences, as well as my observations of others' experiences. th-cam.com/video/6y_pK_ZbB0U/w-d-xo.html --- Here is a video where I did a retest of a .223 Ballistic Advantage barrel in my AP Enhanced. The accuracy and group patterning were approximately the same from the initial upper I used. th-cam.com/video/lVnORd0LbHI/w-d-xo.html --- Here is a video by our great prophet JohnnysReloadingBench, where he does a 60-round barrel heat test with a 18" WOA barrel in a Thermal-Fit BCM Upper, and an Aero Precision Enhanced upper. The AP Enhanced "won." (Note: Doesn't mean it will always be the case.) th-cam.com/video/F47E6CvYB-0/w-d-xo.html th-cam.com/video/RSVS-M9As2s/w-d-xo.html th-cam.com/video/wor9JxS_upA/w-d-xo.html --- these three videos are my Wilson Combat barrel getting ~1/3 MOA groups in my AP Enhanced Upper.
@@danielmottweiler If I do enough testing that I can empirically prove it, no problem! In the meantime, I'm sure there are other reasons to do it - from a manufacturing standpoint. It probably eliminates some needs for some QC steps by making sure you never have to worry about an Upper Receiver is "over-bore," or over-sized for the barrel extension. Who knows? There are other tests I'd like to do to get a better picture of what is going on. 1) Building upon JohnnysReloadingBench's barrel heat/upper heat is one of them. Aluminum is far more susceptible to heat than steel, so if the number of rounds downrange affects the upper, that's important. 2) Testing shifts in the POI due to weight on the platform. A semi-monolithic or monolithic stock is supposed to be best for this - but ARs are not truly freefloated, and weight of the rests, or slights, affects POI. Which Upper style is effected least? Just some thoughts.
Good stuff!😃👍
Good stuff. I am going to be doing a bunch more 6mm arc this winter!

The question is, does a suppressor affect group size over time as the suppressor fills with carbon and becomes heavier?
I have no evidence or experience to be able to rightly explain this, and I only two people that own suppressors.

Question Did you thermal fit your barrel to the receiver?
With the Proof Barrel? Nope.

Tell JP enterprise that thermal fitting does nothing for accuracy.
