Who’s hex coating monos?

[xsn10s]

I got away from moly because of the reports of it drawing in water. And to be honest I really don't need the mess and extra hassles. But the Hex sounds like there isn't much down side. And on my LR rifle I'll be taking more time and care anyways. One question though. Have you guys sent an uncoated bullets down a seasoned Hex barrel yet? If so did you all notice any changes?

You won't see any changes with a uncoated bullet until you send a few down the bore. It could take two, or it could take 20. It just depends on bore condition.

Thanks guys. All this and any additional info helps from those who have "done it".

Hmmmm you guys might be right about Hex not going into sublimation like moly. Or I should say this article is supporting your statements that hex isn't going into sublimation.

One thing I would add is the machined bullets like Hammer & CEB "generally" use some type of cutting/cooling fluid so it is best to wash your bullets in a solvent of your wives most tolerated flavor before coating them. I have found oil/lube on Bergers also so before processing all bullets should be cleaned so the HBN can adhere to the bare surface material.

Good point!
I tried to start a discussion on the oils used on bullets and how I thought they should be cleaned before using even on non hex/moly coated bullets. My theory was some of the high SDs might be attributed to the oil on the bullets going down the bore. Some might be coated with oil and some not so much. The discussion kept going to hex application and degreasing before the process. It was just a thought, and I haven't explored it further.
My thought was, inconsistently lubed bullets are not good for SDs.
That goes for non hex coated bullets too.

Been HBN coating CEB and Hammer bullets for over a year now, no worries.
I wash & dry the bullets and throw them into a tumbler for a couple hours, then shoot them through a treated barrel. Big thing I've noticed is no discernible copper fouling in my big rifle, even after 100 shots. If you already have a load developed for your rifle and switch to coated bullets then you will probably have to rework your load.

I wash bullets in acetone prior to HBN coating them. Buy it in the gallon-size container. I do find other useful purposes for the acetone from time to time.

As to original question, there are no unique problems associated with HBN coating copper monolithic bullets. Use the same process as for copper jacketed bullets.

No media is required when using a vibratory style case cleaning unit.

I've read tumbling media may be necessary when HBN coating bullets with rotating tumbler style units. Broz got better results with tumbling media in his.

That will get things clean for sure. but it can be hard on the liver too. my liver has taken a beating already

Yeah, I try to step outdoors for any significant use of the acetone. Minimize vapor inhalation.
Alcohol is bad enough all in itself.

Is everyone coating the barrels as well? I watched Tubb's video on his coating and he only mentions doing the bullets not the barrel or bore of the barrel for that matter.

You don't have to treat the barrel. The bullets will eventually do it. Some say within 20 shots.

Thank you. Next question if barrels are treated do they have to be retreated and what determines retreatment ?

Once my barrels are stabilized, I don't retreat with slurry. I just keep shooting the coated bullets.
