C4...working?

[Clancy]

Time to break out the bronze.

I did in fact (because someone will ask) try nylon with the c4 and cu2 as well as with eliminator. It was a terrible waste of time. I went back to wipeout and accelerator with a bronze brush….. in a hurry.

WHEW ! I was worried , I thought you were going to blow something up !

Me too.

I started years ago with Hoppes and a bronze brush. That's fine for a hunt rifle, but in F Class with expensive barrels, I'm not a fan of the metal brushes. I only use nylon.

Hate to break it to you.....nylon is more abrasive than bronze

I have C4 but have never tried it. I have used KG for years and thought it was doing a good job. A Teslong showed me how wrong I was. I looked on my shelf and saw a bottle of Witches Brew. I used it with a bronze brush and was surprised at the amount of carbon/copper I removed. I scoped the barrel again after cleaning and it looked like new again. I even had to lower the brightness of the scope light.

Witches Brew is one of if not THE most aggressive abrasives marketed for rifle cleaning. In case you didn’t know.

Anybody use Kroil penetrating oil in conjunction with C4? I’ve been kind of nervous concerning brushes down the barrel. I probably clean more often than most folks, though. After each range session which usually is 20-30 rounds depending on which gun I’m shooting that day. Hopefully it will help me stay ahead of excessive carbon build up. I’ve not bore scoped my barrels. Wouldn’t know what the hell I was looking at anyway!

Try it. They are cheap - the heavy carbon fouling stands right out.
With a borescope, it's easy to see what makes a difference and what doesn't.

I decided to try C4. Back at 600rds, I hit it with JB. I got really clean, but I don't care to make JB a routine. It took 30 rds to get my accuracy back.
So now at 750 rds, I tried the C4.

After a normal cleaning with Wipe Out, I followed the C4 instructions.
I scoped it first and saw the black carbon in the groves. After using the C4, it looks worse! I followed up with another Wipe Out cleaning. Still black.

Do I just have to keep doing it until it's clean? I'm assuming the C4 only loosened the carbon up some, and the subsequent Wipe Out failed to get the rest out.

Could use some advice.
Thanks.

I’ll probably get torched for saying this but I don’t care for JB and solvents are all about the same’ so I just clean with Bore tech until I get tired of having a half ass clean barrel then I use dab of Thorroclean wrapped around a Soft nylon 6 mm brush for 6 mm bore to get in the grooves.
A few passes and presto clean O’

I'd like to hear more about this.

Thanks!

Mixing oil and water is what mixing kroil and c4 is doing. Literally.

I don’t actually mix them together . I use them in a sequence, separately. Couple of patches soaked with Kroil, let it sit for a while, dry patch. Couple of C4 soaked patches, sit for a few minutes, dry patch. Poorly stated in my original post.

You say that like it’s a bad thing? Just quicker. For those who don’t wanna soak it, make it last all night, skip the forplay, have the job done in a couple minutes.

Are we still talking about barrels?

Witches brew is great.

I do. What about it? Use it accordingly!

If you’re using Bore Tech c4, eliminator, etc keep in mind they are like 80% water so they aren’t very aggressive, bc of that they need to soak for a few hours to really do their thing if not using a brush. Also since they have water its best to dry patch thoroughly after using them (Or you can run a few wet patches of Isopropyl then some dry patches) then run a light patch of mineral, paraffin, etc oil as a protectant then before shooting run a dry patch.

BT claims their solvents contain a short term protectant but some barrel makers (Frank Green at Bartlein) have found that people who only use BT as a protectant (by leaving a light coat in the bore for storage) can lead to corrosion, possibly bc people left the high water content solvent in the bore too long (more than a few days) and the air/water reacted with the fouling “sweating” out of the bore causing corrosion.

Last thing in my barrels is a couple of Clenzoil soaked patches followed at the very end by a dry patch.

I do the same in my AR-15. As a protectant the best CLP’s seem to be Clenzoil and Lucas Extreme CLP. If you don’t have any of that on hand or want to save some $$$, mineral/paraffin oil will also work. Hoppes gun oil is pretty much 100% paraffin oil if you look at the sds and it has shown to perform pretty well in SS corrosion tests.

I always use Kroil after I JB a bore. I use it to remove any particles of JB, and to clean the bore. I generally run 4or5 patches of Kroil, or until it looks clean. I DO NOT depend on Kroil as a protective oil in the bore. I use it as a penetrating oil to help remove any stuff in the bore.

Thanks. Yes, that’s what I use Kroil for. I finish up with Clenzoil as a protectant.
