I was just watching lowlights newest vid and saw him using "ceramic paste" loading up some 338NM. Anyone ever heard of this and biggest question...why.

Raucous,
The compound that Frank is applying between the two rear engraving bands was tested on the 25mm Bushmaster, and found to increase throat life from 40 rounds cyclic mode, to 2,000 rounds @ 200 rounds per minute.
I do not know ZA barrel life expectancy when used as Frank's video demonstrated, but it should increase significantly. ES holds in the low single digits as an incidental benefit. This is important within the ZA system for two primary reasons; First, I use eighteen grooves, which concentrates a great deal of heat in outside corners of the small lands at the forcing-cone. Second, ZA loads are going to be hot by design. I had the choice of moving to extremely expensive barrel alloys, or find a way to make iron-based alloys live longer in a high heat/pressure environment.
Questions hitting my in-box centered more on the ceramic lubricant than on other aspects of the ZA system... probably because it was mentioned this also works well with conventional bullets. However, I have not done a great deal of work on that application. The video is intended to give readers some idea of how to load banded projectiles in conjunction with the lubricant.
Really, an added step in your reloading process... LOL
Sounds like a valid reason to me... if you get 2000 more shots out of the barrel your money and time was well spent. it's not just for solids as you can treat your bore with a single patch of it.
Narrow minded people always see a problem and never a potential solution. The gimmick is putting it down before testing is complete. Plus I am doing all the work for you so if it does nothing, I'll know long before you will, and will say so.
I don't see how that is narrow minded.....
If I can afford $2/copper solid + all that powder to send that projectile down range 3000+ times, whats the cost of a rebarrel? Barrels are a consumable and aren't all that expensive especially against what it costs to send a copper solid in a 338NM down range. Shit if you were deadset on sending a shitload of rounds down range I'd just get 2-3 barrels spun up all at once and buy yourself a barrel vise and an action wrench.
Just a different prospective.
Good luck in your testing and keep us posted if this does reduce throat erosion.
I guess you missed the part about conventional bullets... The fact if it works with solids it will work with anything.
You can just use it in the bore and not have to coat the bullets like shown.
and narrow minded because you don't know the first thing about it, but called it a gimmick.
I think that what Frank is trying to impart to your way of thinking is the fact that 'what if...' you could get another ~2000 rounds of accurate fire out of that barrel that you're going to replace after only 3000 rounds? Wouldn't another 67% of barrel life be worth the minimal effort, even when using this stuff in just your bore, to you? Even another 1000 rounds, or 33% more life, might worth the trouble?
Instead of rebarreling three times, you're only rebarreling twice, over 10,000 rounds. Barrels for these big guns are $400-$600 before mounting, so unless you're a wealthy guy with money to burn, this ceramic paste might be worth the small amount of elbow grease, no?

Benchmarking is my friend.....................interesting to see the results!Plus I am doing all the work for you so if it does nothing, I'll know long before you will, and will say so.
