TPM - How to Clean Your Precision Rifle Barrel Pt. 2- Chemicals vs. Brushing - Tested and Explained

[@BarbosaUral]

You say this is an un-scientific test/study. I say it's as scientific as you can get without a full blown lab. And dare I say it, you soaking jacketed bullets in solvents/cleaners plus the microscope was a stroke of genius.

[@triggeredprecisionmachinellc]

Well I appreciate that. It would be awesome to have an actual lab at my disposal to play around with! 😁

[@garysides636]

Thanks for such a comprehensive review ....I have two new barrels being fitted so I'll be using wipe out for that process with some bore tech eliminator. Merry Christmas ⛄

[@triggeredprecisionmachinellc]

Awesome! Thanks for watching and Merry Christmas!

[@toddb930]

Lots of good information there! Thanks for sharing the results you obtained. This helps confirm some of my cleaning process and question other parts. On the KYL targets, that cleaned all five shots, how many people were able to do that on their first attempt?

[@triggeredprecisionmachinellc]

Hey Todd! I had 42 perfect targets submitted for the challenge, 18 of which were shot on the first attempt. There are some great shooters out there. I almost feel like I need to make the next challenge even harder. 😈

[@toddb930]

@@triggeredprecisionmachinellc -- that's amazing! Thanks for the info. I have an idea for a challenge. I'll email a description within a few days.

[@Blair338RUM]

I assume your copper solvents don’t contain ammonia? And what carbon fouling solvent to you find is the best ?

[@triggeredprecisionmachinellc]

Nope, no ammonia in the copper solvent. I've been using the BoreTech carbon solvent for a few years now and really like it. Its safe and works well.

[@soonersteve3733]

KRoil is generally used with JB bore paste

[@triggeredprecisionmachinellc]

Interesting... I've used JB a few times on rimfire barrels, how is Kroil used with it?

[@soonersteve3733]

@@triggeredprecisionmachinellc primarily as lubricant.

[@triggeredprecisionmachinellc]

Awesome, I'll give it a go sometime.

[@mmgee]

Wow, this was worth watching. Many CF BR shooter are use still using Shoots Choice / Butch’s, would like to know how they compare, I personally have never cleaned a barrel without a bronze brush

[@triggeredprecisionmachinellc]

I used Butch's Bore Shine and Sweet's 7.62 in the past. Sweet's is great but you need to be careful how long you leave it in the bore and boy does it stink! I should re-visit Butch's and test that out.

[@jasonrad9332]

Great info on cleaning, thanks.

[@triggeredprecisionmachinellc]

Thanks Jason, and once again, big congrats for winning the KYL challenge! Merry Christmas!

[@haisardao8224]

Great video, just ordered some of those jags to replace my bronze ones.

[@triggeredprecisionmachinellc]

Good choice!

[@jasonrad9332]

Merry Christmas! 🤘🏻My rifle is famous🤣. Loved that competition. Plan to shoot it often just because.

[@triggeredprecisionmachinellc]

You have an awesome looking rifle that shoots as good as it looks. Great shooting!

[@jasonrad9332]

@@triggeredprecisionmachinellc Thank you!

Merry XMas!

Merry Christmas, sir!

[@jasonmausteller2488]

I noticed you had a non brass slotted patch holder? Who makes that?

[@triggeredprecisionmachinellc]

Its a Bore Tech Proof Positive patch loop. They're made from aluminum so they don't give you a false copper sign on the patch.

[@michakav]

Kroil is general mixed with a solvent to help carry it deeper into the fissures and make cleaning copper/carbon easier. The general mix is 25% Kroil to whatever solvent used.

[@triggeredprecisionmachinellc]

Interesting. It seems that it is always used in conjunction with other things.

[@DLN-ix6vf]

great contest and fair way to pic winner as I'm sure many shooters did very well; maybe next time either all smaller circles or @ 200 yds. as far as cleaner goes and I may have missed it but there are others on KZbin promoting CLR as a cleaner which most have now retracted that idea. think I will stick with Hobbes and follow your suggestions on length of time in barrel and watch my brushes when going in and out of the crown area.

[@triggeredprecisionmachinellc]

Thanks Dave. In my experience Break Free and the CLR oils are pretty useless gun cleaners. They are pretty poor lubricants, horrible cleaners, and decent at rust prevention. Lots of marketing there. I was really impressed with Hoppes BR, it really worked well!

[@Rico11b]

KG-12 Copper Solvent.

[@shadowironbank5469]

Why cant you just place your barrel into an ultra sonic cleaner?

[@triggeredprecisionmachinellc]

I do that with pistol barrels, it works excellent. If I had an ultrasonic that would fit a 26" + barrel I would absolutely use that. It's a great way to go.

[@Rico11b]

It's so laughable that Hoppes #9 BR beat all of those new "modern" solvents. I wonder how it do using the Thorro-clean stuff that many are talking about these days.

[@triggeredprecisionmachinellc]

I had a good laugh myself. I actually went out and bought a larger bottle of the Hoppes for stubborn barrels and sure enough, it works!!!!

[@Rico11b]

@@triggeredprecisionmachinellc I'm actually running your test right now on the foaming Hoppes #9 and Montana X-treme's Copper Killer. That copper killer is so strong it dang near knocks me out everytime I open the bottle so I have to use it outside. I'll let you know how it turns out. I have a week and a half to go still.

[@triggeredprecisionmachinellc]

AWESOME!!!! I've heard that stuff is pretty amazing. Curious to hear your results.

[@Rico11b]

@@triggeredprecisionmachinellc Tomorrow completes the test, so I'll post the results that I get. The bullet I used was slightly different. I used the Sierra 168 grain Tipped MatchKing (TMK) bullet in .30 cal. I'm curious to see how the Montana Copper killer will compare. It smells so strong I can't use it in doors. I think it's mostly Ammonia, but just opening the bottle causes the air to become unbreathable almost instantly.

[@Rico11b]

So after a 20 day soak in here are the facts. Started Apr 2nd, ended Apr 22nd. I calibrated the scale before taking any measurements. Using the Sierra 168 grain Tipped MatchKing (TMK) bullet in .30 cal Montana Xtreme's Copper Killer - starting weight of 168.08 grains, ending weight of 166.06 grains. Hoppes #9 foaming bore cleaner - starting weight of 168.07grains, ending weight of 166.96 grains. I weight each 3 times and it came up the same every time using my Creedmoor TRX-925 digital scale.

[@greg9486]

hoppies 9 clean is clean custom barrels are different than factory

[@triggeredprecisionmachinellc]

I grew up using the old school Hoppe's #9. I'd like to try some of that out and see how it does on copper, if it does anything.

[@shadowironbank5469]

It will minimize barrel wear..

[@triggeredprecisionmachinellc]

Definitely

[@shadowironbank5469]

Light a match at 100 yds, shoot through a candy life saver without breaking it at 100 yds!

[@triggeredprecisionmachinellc]

😂

[@user-TJ365]

If you want to drive yourself nuts cleaning a barrel, make sure you use a borescope. Best yet worst tool I ever bought.

[@triggeredprecisionmachinellc]

Agreed, I love em and hate em.
