simple Hi-Tek coating

[gunoil]

Leadman, u put gas checks on 223?

[leadman]

gunoil, your boolits look great. Yes, I do gas check the 223 and 30-06.

[leadman]

The coating does not need to cover the bottom of the lube grooves or in front of the driving band on the nose. Should be no barrel contact here so not needed.
Thinner is better as far as sizing and no leading in the barrel. I think the thicker coats get gas bubbles that weaken the coating, just my theory.

Well I finally got to test the red copper in all of the 45's today and no leading at all even in the darn Taurus 24/7 That thing has leaded with all cast loads I have tried to date. I have found that with my Lee tumble lube 230 RN I can get by with only two coats but the mold throws a perfect .452 boolit. the Lee TL 200 SWC needs three but it is throwing at .454 and with just two coats when I size the coating seems to get a bit thin. Over all I am liking the HI-Tek coating. my dies stayed clean and smoking was minimal. I haven't noticed any accuracy change with the 45's.

Great post codawolf,,, stain away! "A new word i stole from hi-tek".

Yea, leadman thanks for GC ?. I love this stuff. I want some 223 bullets and some gas checks. just a few to try. My friends shoot-em, not me.
1) what sizer would i need?
2) u get your Gas checks from castboolits? Forgot where i saw it.
3) no , i dont want a rifle, i have keltec carbine/40s&w.
4) paypal

I'm a newcomer to this thread and have been reading with great interest all of the tips, techniques, and procedures. Finally decided to order a half liter of red copper. Though I haven't been to the range to test, I must say that the process is very straight forward. Thanks to all of you for sharing your experience. I will report back with results once I test at the range. Below are some pics of coat 1 before and after baking, and coat 2 before and after baking.

G'day Buff Driver (Muff Diver????)
You bullets look great.
First coat thin. baked light. second coat copper. baked red/copper. Nice

How do they smash and wipe?

Don't sweat it about no colour in the lube groove. or where the nose meets the shoulder on SWC bullets. it may not look good, but they shoot great.

In Testing, I have had coated bullets that looked like a million dollars, but failed badly in the firing. so looks are not everything.


Tonight, I'm going to revisit the black coating. a new mix with the original catalyst to see if the black will be blacker than with Extreme Catalyst.

Thanks, Ausglock. Smash test is good, no color on acetone wipe. Pic below.

BTW, BUFF is USAF slang for the B-52!

Good job!
Now load those puppies up and have some fun...

Hi leadman,
You are quite right about bubbling with thick coats.
What actually happens is, that thick coats form a thick skin on surface, trapping solvent and moisture below.
Even if it feels dry, when putting them into the oven, these vapours become super heated steam vapours, which show up as bubbles, (mini moon craters) and after cure, surface is like an "orange Peel", most common in such events.
Often the super heated vapours stop coating adhering to alloy, as the vapours try to escape between alloy and coating.
As I have advise many previously, simply just "stain at each coat".
This allows faster and more even drying, use less coating, looks pretty, and it works.
With two or three thin stain coats, you should get very acceptable colour and shooting results.
Thanks much for your postings, much appreciated.

What? Did you put that on a train track?

[gunoil]

buff D, u caught on quick. Spent alot of money on Kenworth and tires and food around your area clear down to the TA. My hang-out!

You got dem big dang pistol bullets.

[prickett]

I thought about that and a couple days ago I loaded a bullet with only a primer and launched the bullet into the barrel. After beating it back out the same way it came it the coating was all still on there and no exposed lead no pits in the bore and it looks smooth not sure how i would tell? Also fells fine when pushing a patch through.

I've been using the CZ for the most part but when I started having problems I was using my glock 17 and 75b that day and they both leaded but I haven't tired the glock since.

I shoot my HT coateds through a CZ75 w/o leading. I size the boolits to .358" (smaller did result in leading when using conventional lube - not sure whether it would with HT).

[Thompsoncustom]

Well got another thing to knock off the list of possible causes to my coating nightmare. Tired the glock 17 and the CZ 75b the gun I have been using and both leaded of course. Will try a different load later this week with unique to see if that changes anything.

I had been running bullets at .3565 for the longest time with normal homemade lube and could shoot all day long with no leading. Just opened my sizer up a little more a while back.

I was using 700x in my 9 and got leading. I switched to unique, and it stopped.

I noticed yesterday at the range that the first boolit in a group was always out of the rest of the group. i have been shooting 3 shot groups to save my neck (deterioration and arthritis). I have been pushing a dry patch thru the bore after each 3 shot group and I think this is causing the first shot to be out, so remember this as all shots are included in the group sizes. I also had problems with my Leadsled and my sons AR as the rear sling loop on the side of the buttstock was hitting part of the Leadsled. I tried stuffing things between the Leadsled and the buttplate but it did not help much.
All the boolits were coated with the Red Copper Hi-Tek.

Cool beans leadman. The special forces like for their barrels to get build up, iam told. Shoots straighter. I luv this stuff.
Lots of quick stuff coming out ready in my garage.

You can coat all ya want, but ya still should size.

[Lizard333]

Leadman, you consider leaving your barrel dirty? Some of my rifles, don't get a patch or bore snake through them until I start loosing accuracy. Sometimes I get a couple hundred shots through before accuracy starts to drop off. This is with jacketed or boolits. Now, my experience with the high tech coating is minimal, but the little that I have shot, my barrel was cleaner than with cast. Now, I'm also shooting non corrosive primers and powder, so corrosion is not of concern.

[leadman]

I was running a patch thru the bore to check for any traces of leading. Now that I have the data on what works as far as velocity I will shoot some longer strings. I may switch to the Saeco 120gr RN GC in the 30-06 to get higher velocities. Also will try different primers, seating depth, etc.
The Leadsled may be causing some of the large groups because my son was using it to sight in his 308 with hunting loads and they were larger than normal also. Only problem is I can not shoot anything with any amount of recoil without it to to health issues. I'll figure it out I hope.

gunoil,
What was the weight of the 380,looks like a flat base?
Thanks,
