Missouri high tech coating ?

No Glock here, but I've used LOTSA Hi-Tek bullets.
Even used 'em in a rifle with no leading.

Used .309, .356, .358, .411, .430 & .452

Hi-Tek bullets are outstanding. I use them in all my semi-autos. I've read that they are A-OK in glock's polygonal barrles, that powder coating is real tough, but I do not have any first hand experience. My glock 19 has a Barsto conventionally rifled barrel in it.

My revolvers are MBC uncoated lead only, because I like to save the few pennies, and they've never seen a jacketed bullet. Never had a problem with any of MBC's handgun offerings

Many coated bullets have gone through my Glocks with no leading. The only gun I own that gets leading with coated bullets is a Browning Hi Power.

Never fired in a Glock, but have fired them in a polygonal CZ82 9x18. No leading there, but it is a low velocity round. They were really accurate in this application, but my reference is Wolf FMJ, so take with a grain of salt.

Overall, I've had mixed results with HT bullets from MB and ACME. Good in 9mm, but could never get the accuracy to the level of FMJ or conventional cast. I do still like them in 9mm though, as accuracy is relative for me in these, and I like the cleaner shooting and slick loading of them, and am willing to compromise some precision for these benefits in 9mm.

I don't like them in my revolvers, accuracy suffers vs conventional cast or jacketed, and I shoot more precision type targets with these so I have dropped the coated bullets in these.

I shot many 124gr coated bullets from the MBC in a G19 and tried to make them fail. I loaded a max charge of Longshot which generated just over 1200fps and no leading at all. That coating is very tough. Accuracy did not degrade either.

Love the MBC 9mm cone. No leading in my new 9mm 1911.

Use MBC Hi-Tek coated 9mm and 40S&W bullets in my Glocks and no leading issue.

Just be careful when reloading not to scrape off coating.

Hi-Tek is not powder coat.

Just because it is a powder, that doesn't make it "powder coat." Hi-Tek is mixed with acetone as a carrier. Powder coat is applied electrostaticly.

No, it definitely is not powder coat. The product comes in powder form that is mixed with acetone to produce the liquid coating. See the instructions posted on MBC: http://missouribullet.com/assets/source/J&M_Coating_instructions.pdf

Okay, it's "powdered" and not "powder". I didn't catch that.
I knew a guy that did powder coating in his garage as a hobby. My small understanding was the item to be coated had a electrical charge run throught it to attract the powder to the surface, then baked in oven. That coating seemed quite durable.

Yes, powder coating is pretty durable, but the Hi-Tek coating MBC uses (and sells for DIY) is more durable (and does not involve electrically charging the bullets). I have seen video of people melting the lead out of the Hi-Tek coated bullets leaving the formed coating intact. Also have seen some Hi-tek coated bullets after shooting that had almost no damage to the coating, even where the lands contacted the bullet. That probably varies by firearm, though.

It does look messy, and I would not care to work with acetone all that much. I think buying the coated Hi-tek bullets is a reasonable expense for me. (But plated bullets from RMR are almost as cheap! So many choices!)

Missouri Hi-Tek bullets have been great for me so far...granted all I've ran is 38 and 44 special, but they are both accurate and don't lead my barrel.

Original Hi-Tek Supercoat (OP, notice the trademark spelling.) was first imported from Australia by Bayou Bullets.
They were the US distributors at one time, I don't know if MBC et al are still buying from Bayou or if they are ordering direct from Australia.

There are a few places using other polymer coatings, not from Hi-Tek. One such is Blue Bullets, also Precision Bullets.
