A saw reference to these but did not look them up until now. I am going to order some. If anyone is interested in sharing shipping, let me know.

On a related note, what are you thoughts on these:

#1 Carbine - Hi-Tek
.309 Diameter
115 Grain RN
Brinell 18
For the M1 Carbine
Hi-Tek 2-Extreme Coating
Price per box of 250
Price: $28.00

It would be interesting to see how much lead these guys leave behind.

It would also be interesting to fire these and the ones you reference above into some ballistic gel. Mike, do you still have any gel laying around?

[Rumbler]

Yes. Still have the gel and the cooker to reconstitute it afterward. :)


I'm trying to learn more about their "Hi-Tek" coating. I would sure like to jump to the conclusion it means "supersonic is not a problem". But I'm not sure that is the case.


Looking at the magazine (Blue Press) I see the word "BluePress" can be entered in the "promotion" box during checkout for 5% off the order, and that they have a 65 pounds for $14.00 flat rate shipping too.

[FLT]

That's interesting . Do you think they're powder coated?

[polebarn]

It sure sounds like either Cerakoting or a solid form of Exxon Mobil 1. I know that sounds goofy but the company really specializes in lubricants. I wonder if it's a variation on the moly coating Black Hills uses.

[FLT]

$20 for enough to do 16 thousand bullets . You can't complain about the cost.

[wheelman]

ok

I am going to order some up and I will pick up a box of the 115 grains just to play around with.

get the gel ready. :)

[FLT]

Anybody know if I will need a cast bullet expander to flair the case mouth so as not to shave lead to load this bullets?

[wheelman]

From the research I did on the web yesterday, more than one indicated that it would be needed. I think all were referencing using cast bullets made at home.

Given the fact that I forgot to order one in placing my midway order - odds are that it will be needed.

If you are talking about the Missouri Bullets, maybe we will get lucky. I have found those to be pretty good with respect to specs (for 45 ACP and 38 SPL).

Not really an answer but you are certainly on the money with your question. I will let you know for sure in about a week for both home made cast and Missouri.

[FLT]

Thanks.

[wheelman]

ok

I just ordered up 250 245 grain, 250 115 grain, and a 100 sample pack of assorted. All with the Hi-Tek 2 Extreme coating. The following is from their FAQ section:

What are your coated bullets?
We start with our own lead cast bullets. Then we treat them with the Hi-Tek 2-Extreme Coating from J&M Specialized Products P/L. The Hi-Tek 2-Extreme Coating is a lubricant that is bonded to the bullets by heat curing. Lead fouling and smoke from wax lube are non-existant due to this coating process. We selected the Hi-Tek 2-Extreme process because it produces a very durable and smooth finish with superb lubricity.


On a related note, the 115 grain are intended for the M1 Carbine. I looked up the muzzle velocity for this cartridge and it is listed at 2000 fps. I assume these guys would not list this bullet for use in the M1 Carbine if leading was a problem at that velocity.

[Rumbler]

I agree completely.

So far the fastest BLK load I have made was right at 2450-2475 and that dang sure was not a 245gr bullet. Even I am not that . . . . curious. ;)

[wheelman]

what weight?

[Rumbler]

I'd have to look at my records to be certain but I am 99.9% it is BOTH the 110gr Barnex TAC-X and the 130gr barrier bullets.

[wheelman]

I wonder if this magic coating will allow for a new high in the fps category as lead usually is faster than jacketed?

[Rumbler]

My experimenting in that area has been limited to the 9MM pistol.

But beyond any doubt I can run coated lead fast enough to make plated bullets fly apart before arriving at the target. Even at 10 yards or less.

It is a different coating;" gator snot". But I believe it is proof of concept indeed.

[Rumbler]

. . . . oh, and I'll be more than happy to push some of those bullets you ordered to their limits to find out. :satansmokin:

[wheelman]

I am thinking this might just get me back out to Talon.

115 grains at 2450 equals around 1500 ftlbs

not bad for a poodle shooter or a single shot in my case :)

[wheelman]

This is from the Hodgdon site for a 115 grain (I assume jacketed)

I am thinking this must be getting close to a full case.

Hodgdon Powder H110
Bullet Diameter .308"
C.O.L. 2.050"
Starting Load
Grains 18.8
Velocity (ft/s) 2,220
Pressure 39,300 CUP
Maximum Load
Grains 20.0
Velocity (ft/s) 2,348
Pressure 50,800 CUP

Mike - you ever play with H110 with the light bullets in this caliber?

[wheelman]

Note - 20% increase in pressure with a 5% increase in powder between starting and max.

Also on another note - heaviest bullet they show is 230.

[Rumbler]

I'm loading H110 almost exclusively for supersonics now. The results I am getting are that good. :)


Check out the handload section at: http://www.300blktalk.com/forum/index.php

There are hundreds of recipes and their results posted there in every bullet weight and configuration you can imagine.

The guy who actually developed the cartridge - runs AAC - is the same guy who owns the forum. He is surprisingly active there.

This is an interesting one. BTW - you gotta be related to this guy LOL

[Rumbler]

Sure looks like he is onto something. I'm thinking he is very close to max. The primers say "no" but the ejector marks say "yes" so hopefully he is treading very carefully.

But you know . . a 240gr bullet traveling ~1400 FPS is nothing to sneeze at. I'll bet that hits like a ton of bricks.
