simple Hi-Tek coating

[M.A.D]

MAD.. a 20lt bucket of 9mm cases would be good...

Ok, Will start collecting, Since its coming towards the end of the year, We will be flat out 7 days a week with everyone getting their shoots up. Wont take long to collect a 20 for you...

Thanks Mate, I’ll raid your bottle if I get my act right with the Mk1 experimental run !

Not an issue, i'll sit them a side, if it works, i can possibly wrangle up more for you too.

We get the exact same situation at my club, heading to July,you see people you haven't seen for 12 months!

H&G #130, 185 grain SWC. BHN 8 @ 1000fps. Soft,wet berm. Hi-Tek TMG Gold.

I was shooting clays @ 25 m, you can see some orange pieces stuck in the bullets, indicating that I actually hit clays.

I bet you just sprinkled the clay dust on them

From the shape of the recovered projectiles, they sure were moving and hit hard, no leading? (not that i'd expect any)

Stationary, hanging clays at 25m? With a pistol? Hard.

Thrown clays at 25m? With a pistol? VERY hard.

Out of curiosity for you 9mm/38 Super shooters, whats the IDEAL diameter of the lead projectile dropped from the mold for Hi Tek coating?

.359 to .360

Not thrown.

Just clays laying on the berm. Not hard with a good load.

.359 to .360

Seriously? Then what do you size it too after you have coated it?

[Tazza]

I size to .357 works great for me

No leading, even though I'm svaging the bases a little. Takes a while to get expanders from overseas. I've never tried this soft alloy before,except shotgun slugs.

About svaging, I loaded some unsized 454's, they plunk fine with the same 472 crimp setting. To my surprise, pulled 454's look just fine, no base damage whatsoever -and they get svaged to perfect 452. I didn't think Lee Universal "expander" would work this good.

anything from .356 to .358

I've been test driving this STI for a few days now.

I took it straight to the range with a few boxes of factory FMJ:s,all good,or should I say great. I then decided to clean the copper out with Eliminator before trying my Hi-Tek ammo. Well,to my surprise there was LEAD,too. Most probably from Magtech SWC ammo that the vendor sells,very few people cast pistol bullets up here where I live. The lead had been there before my few FMJ boxes.

So much for "shoot the lead out" that I still see recommended around... But hey,no problem,enter "The Dip":

Plug the barrel:

.

Carefully fill the barrel with The Dip and watch it bubble:

.

After two minutes,pour The Dip away and push the residue out:

.

For STAINLESS barrels only. And yes,you get lead acetate which is bad stuff,use common sense. My Dip is very strong, using 50/50 strong household vinegar / 30% hydrogen peroxide. If you fill a cup with The Dip and drop a boolit in, the boolit bubbles away and completely disappears in a few minutes.

The Dip is very handy for lead disasters like this.

I'm very impressed with the Hi-Tek coating. I sold some boolits to a couple of IPSIC guys who wanted a good boolit for their 9mm Major Open guns. To get to power factor in Major with a 125 gr lead boolit you have to load hard and make them fast. The PF is 175.

At last weekends matched he chronoed his load to right above 1400 fts. He swore it was no leading in the barrel nor the comp. This is impressive to me since this actually is "gas check territory".

Just thought I should share this because this is to me a true test of how though this Hi-Tek coating is! For the record, it was Gold 1035 with two coates baked at 12 minutes at 200 C. The boolit was Magma 125 gr TC sized at 357"

Hunter74, I have shot hundreds of RCBS 45-325-FN:s @1900 fps with a 45-70 Marlin. Flat base. No GC. My main plinker load, I do timed practise etc... It's a stainless gun but I never needed "The Dip". When alloy and size are right,Hi-Tek can be used with quite a bit of velocity/pressure.

I got the STI sights adjusted today. Fired one box Hi-Tek TMG Golds during zeroing, I saved this one round for a picture. I took the pic at a bench,75 m from the berm.

I then loaded the round,aimed at a fist size rock on the 75 m berm - and missed the rock by two inches, hitting right above it. Considering I already fired 49, BHN 8, loaded them unsized 454 without proper expander,only flaring... this is just great.

YOu might want to let your mate know that IPSC Open Division is now minimum of 160 Power factor for Major. I run a 125gn SWC at 168 P/F in my 38 Super STI TruBor. 9mm Major is starting to make a come back here in OZ. A few BUL open guns are now running 9 Major.

[hunter74]

I'm sure that I'm the one's wrong about the PF.... Anyway.... they are well above and he's happy about the boolits. They were cast from 2sn5sb93pb alloy and I'm guessing that the time in the owen to cure the coating, does a fair share of heat treating as well. In antimonny rich alloys, could this also add beneficial factors to the alloy itself?

My bullets with candy apple are passing the acetone wipe test every time, but fail the smash test every time. Thinking of changing to MEK next batch to see
if its the solvents fault. Currently using Bunnings acetone.

What alloy?
Diggers acetone is fine. Just keep the lid tight.
Applying too much per coat?
Not letting it "Dry" before baking.
