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.
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?
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.
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.
Hooroo.

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.
