Where did you get it? Is Bayou Bullets selling it now?

well heck, may (#3) have to try that next. Yea prickett BB.
where you been Gunslick? Haven't see you here for awhile.
it was back in 96. our firearms lobby groups failed us. They were trying to keep their own little bit of shooting at the expense of the other groups. Shooters are shooters own worst enemy.
We got shafted. there were some of us that were prepared to stand together against the buyback (stealback) but we were targeted by the police for "special" treatment if we did not comply.
Very true words Ausglock.
A number of trapshooters at the club did not have a problem with AR15's being banned after the Sandy Hook hoopla. They idiots did not realize that it is the thin edge of wedge the anti-gunners want - eventually the rationale will be, "why do you need a semi-auto shotgun?" and on and on.
I feel for you guys. What they did was so wrong.

we now have new shooters that have never used or even held an AR15 or Mini14 or M1A or Rem 870 shottie. They now say "why did you need semiauto" my answer is " cause they were fun"
The world has truely turned to schit.
I hate to correct you. But.....
YOUR world has turned to schit. Here in the US, in Arizona, MY world is just fine. I own and shoot ALL of those guns and more.
Every day I make a conscious effort to prevent my world from going the way yours did. Your situation gives me the fuel to fight ALL REASONABLE gun laws. I see where it can go, and I want NOTHING of it.
Not true at all Ausglock, I personally know more than I can count on both hands.
I cast for 30/30, 45/70 and 22 centre fires, most though don't push the velocity envelope and are happy under 2000fps.
I will be trying HiTek with all of these when I get around to it but only because I am already set up for to do it with pistol boolits.
Most probably can't see any value it setting up for HiTek given the limited volume of projectiles they use and as they are happy with the results they already get.
The blokes getting the best accuracy with cast in Aus are probably the long range BP crowd but for them HiTek doesn't offer any advantages. I know a few silhouette shooters who have played with cast but they almost all use jacketed exclusively because they couldn't get the results they were after with cast regardless of lube.
I will more than likely end up using HiTek for my lever action silhouette shooting, but we are only talking 200m and it means I don't need to push velocity, my current 45/70 load only clocks 1450fps with conventional lube and 2-3moa gets the job done so no need to push velocity.
I was there last week in phoenix for professionnal training, went at scottsdale gun club, I shot some full auto M16 and UMP45
can you say fun, best 200$ spent in 5 minutes.
grand canyon is nice, so is hiking the camel mountain and the other one with the weird name. cactus garden nice also ;)
I doubt there are very many casters anywhere that are running anything like that at full throttle and if they are then I would guess your looking at heavy for calibre boolits resulting in lower velocity anyway.
I do load cast in my 222 but again not looking for velocity, a load that duplicates 22WMR ballistics is what I use. Once I have one sorted with HiTek I'll work up a similar load for my swift.
Still I think there would be more than a handful in Aus that are loading rifle to 2000fps+, I know I sell the odd box of gas checks in everything from 22-45 and if I'm selling them then the gunshops would be selling far more.
PTA arrived, safe is in a bolted, XL650 arrives tommorow, but its range day for me and the wife, so the press will have to wait till sunday, lucky Monday is a public holiday...
With pistol at home I can start on the testing on OAL that cycles and other customizing tweaks to suit my firearm.
Getting very close to being able to run the hi-tek testing program for my barrel.. looking forward to it actually.
I took some of the 22 cal. Bator boolits coated with Hi-Tek to the range yesterday. I was trying to see how fast I could shoot this 50gr boolit without leading.
I used H4895 again and when I got to the last load of 27.5gr the velocity average was 3,619 fps for 3 shots. Accuracy was unimpressive at 2.9" but I will work on this. The practical maximum velocity is just under 3,500 fps with accuracy less than 2" for all loads.
The Bator boolits were cast of linotype and then heat treated. Gas checks were Hornady and primer was WSR. The gun was my Contender with a 23" bull barrel.
One thing about heat treated lino is the bhn is very hard at 35 and remained at 32 after coating and baking. On one batch of the Lyman 45gr RN 22 cal boolits I tried to install the aluminum gas checks after heat treating. This does not work well at all as the aluminum extrudes down below the base of the boolit. Install the gcs before heat treating if you use aluminum.
I also tried some boolits in my 22 K-Hornet with no gas checks and they would be ok for 50 yard shots with the gas checks they are much more accurate.
leadman,
That velocity is very impressive. Even if you had to dial it back to 3000 fps to get 1.5" groups it would MAKE NEWS!!!!! Heck, even at 2500 fps it would be a significant step forward.
Three shot groups are OK for a 'rough cut' to see if a load has potential but then the work starts. I assume that is what you are doing. Looking forward to your progress on this and a few five shot groups as you zero in on the load.
There is a thread where I hope people working with coated bullets will publish success stories - see link:

Thanks for posting. Again, well done.

Leadman,
Thanks for your testing and posting of your results.
Currently, we are going to do some work, to determine engineering requirements for alloys so we can reproduce Jacketed ammo accuracy, using specific alloys only, and coated with the Hi-Tek coatings.
What is being considered is, that Soft Lead is enveloped with Copper Foil of various thicknesses and various hardness and malleability.
The Lead, during shooting, hydraulically seals the Copper against the Barrel, and the Copper
"holds "the shape of the contained Lead alloy.
We are aware, that for higher velocity applications, the Copper Films may be much thicker to withstand conditions being generated.
It is also a factor that you need very good sealing of Projectile to Barrel in order to reach maximum power use of burning powder.
I tried to express my concerns previously, that the requirements to shoot with coated cast projectiles may be an engineering related problem, this suggestion was frowned upon.
However, I am not daunted by sceptics at all, and, snide comments made by some, is not a new experience for me.
My understandings with harder alloys is, that because of the hardness, the sealing aspects in the barrel during firing may not be achieved to reach maximum power efficiency, and that is why it may be the main cause of loss in accuracy.
One of the areas that will be investigated, is to try and use a coated hard projectile with larger diameter, to allow some compensation for inadequate sealing taking place with the harder alloy.
It is hoped that by use of a much tighter fitting coated hard alloy, the accuracy can be maintained and also we can maintain speed.
The other aspects being investigated is to not use gas checks at all with harder coated alloys.
Rationale used is, that with combination of larger diameter coated alloy, and the coating having high heat reflecting property, may offer adequate sealing and heat reflecting property, so gas checks may not be required.
Hopefully, we can make good progress with such tests and obtain results which can be then posted.
Now, the first step is to determine most optimum alloy composition/s/hardness, to start doing these tests.
In the 223 Rem Contender I had sized the boolits to .225" but I may load some unsized boolits to see what happens.
Install the gcs before heat treating if you use aluminum. Actually, install before coating works best, copper or alum. Joe, I've been testing 30/30 165 sans check (PCd) and getting decent accuracy somewhere between 16-1800 fps - haven't chronyd yet. Normal 311 sizing - it's the base band strength & shape that gives the accuracy, not just sealing. There is a good reason for short BT base design in jacketed. If you convolve (I know, math) the PB or BT base muzzle exit, the BT has much lower gas exit velocity thus less steering force on the base. Effect works the same for slightly rounded GC base, plus the nice uniform base.
