.45 ACP 230 grain bullets
What is the difference between 230 grain totally copper plated bullets and 230 grain FMJ bullets? Are they interchangeable?

Yes they are interchangeable. A fmj bullet has an exposed lead base. A total copper plated bullet is just that. The only advantage a total copper bullet has is its use indoors where limited ventalation is a problem. Lead exposed to heat can be hazardous, thus using fmj bullets with an exposed lead base, when shot indoors the soft lead base can expose the shooter to vapors. N

What is the difference between Plated Bullets, Full Metal Jacket Bullets and Lead Cast Bullets?

1. Plated Bullets - Berry's Preferred Plated bullets begin as a swaged lead core. The plating process works through electrolysis. The swaged lead cores are tumbled in an electrically charged cyanide bath containing high-grade copper ingots. The copper clings to the lead and the longer the bullets remain in the bath, the thicker the plating. Our bullets are plated to the correct size and then taken out of the bath.

2. Jacketed Bullets - Jacketed bullets start with a copper cup, which is "drawn up" into the form of a jacket. Lead is then infused into the jacket.

3. Cast Bullets - Cast bullets are made up of lead that has been poured into a bullet mould. These bullets come in various hardness levels depending upon the alloy of the lead. All of our cast bullets are lubed and all have the same hardness (about 20 bhu). We distinguish between Hardcast and Cowboy only in that our Cowboy bullets are often used in Cowboy Action Shooting events. html

Use loading data for cast bullets when loading plated bullets.

DO NOT use plated bullets in Glocks.

There is also a Total Copper Jacketed bullet that is different than plated.

I have never owned a Glock and probably never will, but am interested in your comment to not load plated bullets in Glocks. Care to explain?

I hear the story tat plated bullets are bad in Glocks. I blew up a G21 in my younger years foolishly shooting lead. I have been loading Ranier and Berry's plated bullets in stock Glocks for more than a decade. I pushed Ranier 125 plated bullets to 1400 FPS out of a G32 in 357 Sig. Add to that 10's of thousands of reloaded plated bullets in .45, 357 Sig, .40, and 9mm for Glocks with no issues.

MSUP 752, got to ask how shooting lead bullets blew up a Glock? I have never delt with Glocks so this is interesting to me.

Glocks are not made to work with lead bullets. I would assume there was a pressure increase due to leading and boom.

Glock uses a polygonal rifling instead of lands and grooves. Glock tells you not to use lead bullets.

Plated bullets have a very thin outer coating of the plating metal. Jacketed bullets have a thicker jacket- usually cupro-nickel alloy. Much harder than plating over lead. TMJ- Total Metal Jacket- entire lead bullet inside of jacketing metal.

Yeah, what he said. Over pressure from using lead caused a big boom in my hand. The feed ramp and chamber split open. It shot the mag out in pieces and blew the mag release holes open with lots of fire.
The gunsmith I took it to said the pressure was tremendous and he was shocked to see such little damage to the polymer frame and yet the metal was cracked a half inch.
The pistol was rebuilt using a Wilson combat barrel and a new mag release and that was it. Tough guns! I only had some minor burns from the mag release holes.
