Trouble with coated bullets

[Coop]

I have been having trouble trying to load coated bullets (MBC). I have been using their lead 200 gr. SWC (.45 Auto) for years with out a single hitch. With their coated bullets if I get them to pass the plunk test they nose dive, if I make them longer they don't chamber. Thought I would ask here before I go back to lead. Any thoughts?

Pardon my ignorance sir, but what are they coated with ?

Not your ignorance but mine - I have no idea, they call them "Hi-Tec"

The coating is made in Australia and imported here. We are currently lined to up distribute this coating along with unsized/unlubed bullets so that folks can apply the coating themselves. The coating itself consists of a catalyst which binds a polymeric colorant agent with acetone which is then applied in bulk to raw bullets and baked onto the bullets' surface at nearly 400 degrees. The coating is a polymer (bonded with metal) and forms an extremely tough new surface for the bullet. The application of the coating is repeated for an additional coat. The bullets are then sized normally but not lubricated, as the coating itself acts as bullet lube. Nominal bullet diameter is not affected.

Coop, no sir. I am ignorant of that entire process. Interesting to learn about though.
From age d8ve my father utilized child slave labor to wipe down the home cast and homegrown bullets we used on our farm. That was my sister and me.
Even on my twenty two years as 11-Bravo the armored would say, be sure their is no liquid on your ammo or your weapon will not feed or function properly.
We could die if that rifle refused to work in the field during an op.
I wish you success in your endeavor and thank you for the explanation.

Thanks, Richard for the interest and comments, I spent my afternoon adjusting my seating and factory crimp dies to these specs. The rounds now fit the gauge, they were a little off on the crimp. I'll get back after I get to the range again. Might be a while as I'm having heart surgery but I don't know exactly when.
Talk to you then.

May God be with you and the whole surgical crew when you have your heart surgery.

Praying for a full recovery to your heart surgery.
Good to hear you figured out the issue with the coated bullets.

That is a nice knife there. I am going to find my own. K I rs are like holsters.
I used to buy Benchmade, but USCCA offered a nice otf from Krate.com. Very well made with lifetime warranty. Can't say enough good things.
Knife attachment, barrel. Some stuff you cant unlearn...

Thank you for your prayers, I am a pastor and believe that they really help.

Yes prayer absolutely changes things.

I also believe in the power of prayer. God wants to have a relationship with him, as evidence by His time with Adam & Eve in the garden of Eden, before their fall , made by listening to the serpent & ignoring God's instructions not to eat from the forbidden tree. Prayer sent for your medical condition, that surgery is successful & for rapid & complete healing.

I'm a big fan of Hi Tec coated bullets..the bigger coated bullet sellers use that process, i.e. Bayou Bullets.
HI Tec coating reportedly was used / tested in Australia for 20 yrs. before coming to America. I bought some after reading about the process, to try them , as I had been using hard cast bullets almost exclusively for my handgun ammo. I really disliked having to scrub lead from barrels. Loaded some ammo w/ these new-to-me Hi tec coated bullets & test fired them, by shooting a few into the ground, then examined the bullets. The coating remained intact, did not flake, peel, or separate from the lead. Before using these bullets, I read about the lube (or chemical that acts as a bullet lube) within the coating, as I was concerned that the coating would cause bore wear. I've shot thousands of these coated bullets, from a variety of bullet manufacturers , am very satisfied with their performance.

I've also read about some people using powder coating on lead bullets. I wouldn't use a powder coated bullet in my firearms, as I'd be concerned with bore wear. Powder coating in very hard, & I've read nothing about it's effect on a bore. As always, "YMMV"

I've shot thousands of coated 200gr lswc through all 3 of my 1911s. No lead and extremely accurate. I use 4.8 gr of Bullseye powder
