9 mm with BLL

[fiver]

I see no purple...

what were we... oh yeah.
the cz-75.
I bought one of these [the B-retro] and have tried to wear it out in the last couple of months.
I use the same mold as brad [odd since I designed it :lol:]
my load of red-dot is a bit lower than Brad's.
but I went a click harder than ww alloy and run them through my 358 sizer, it's been a non event for about 400-500 rounds now.
I decided on the harder alloy after about 200 rounds, so the round count is getting up there now.

Fiver did you say you designed the 120 tc lee mold? It is one of my favorite molds.

I think he means the 120 RN I have from HM2. It is a good shooter also and I know Fiver designed that one.
I am trying the 120 Lee to see if I can eliminate that little bit of pesky leading I get. That is the reason I'm trying some different size bullets too, I want that leading eliminated.

That makes more sence. My bad.

 

[fiver]

it is the HM-2 mold I designed, not the LEE [I ain't that famous ]
anyway the HM mold has a short bore ride section to the nose to help it align better in the smaller diametered barrels. [you know the ones with minimal/no throats]
it's tapered so that you get it in the larger barrels too, just not as much contact. [and allow it to be used in a 38 special for target work]

I think part of the issue is the sharpness and slight under cut to the rifling in the CZ pistols.
that's why I went to the slightly harder alloy and larger diameter.
it seems to have cured my slight leading issues I encountered with the new pistol, and they still work in my other 9ms that weren't giving me issues.

 

[Brad]

I haven't tried .358, yet. I'm getting closer. I have done .357 and .359, both give slight leading.
I also can easily add a little monotype to my range scrap to harden it a bit.

You have me thinking fiver.

 

[Ian]

A quality, straight-tapered alignment punch, some bullet lube, a block of hardwood, and proper application of a BFH will cure your throat woes. Just sayin'...

 

[Pistolero]

Amazingly, the lube arrived in fine condition. I really can't thank Rick enough, and
wish I could have paid a fair price for it.

In any case, it WILL go to good use, and will lube many bullets for me. 9mm is one
of the calibers that I use Javelina on, so there is some connection to this thread's
original topic.

Thank you very much, Rick. And you are owed way more than a mere cup of coffee!

[Rick]

Your very welcome Bill but that's not a mere cup of coffee, that is my drug of choice.

 

[fiver]

if you only knew how many things I fix with a BFH.
I actually put a oil pump in a ford 292 with one once and drove it another 50-k.
they call me Thor at work for a reason.

 

[Brad]

I have a tech who is like that at work with printers. I frequently tell people not to "Tonya" the printer. Plastic doesn't respond well to excessive force.
It tends to make me break out a BF Foot.

 

[freebullet]

Do you think softening the alloy may help? Seems they may be hard for the pressure.
The xd gobbles up near pure with tl and 4gr red dot with no leading at 356. Never had a cz.

 

[fiver]

it might could, heck ignoring it until accuracy goes off, changing powder speed, or lowering the powder amount might fix it too.
sometimes you just get a little leading down in the corner of the rifling and it never builds up, changes how much is there, or affects anything.

 

[Brad]

I have shot a fair amount of plain old range scrap. Most was water dropped, I can easily try some air cooled.
I may just drop a bit in powder and see what happens that way. Heck, I suppose I could even crack open that new 8 pounder of Promo and see what 3.5 gr of that does.

 

[fiver]

if you lived about 1500 miles closer, I'd give you a sample pack of different powders to try out in the 9mm.
you'd be doing me a favor.

 

[Brad]

My wife isn't going to consider moving closer.......

What sort of suggestions do you have? I have Red Dot, some Bullseye, surplus 105- it isn't really an option, it is saved for 45 Colt. I have HP38 too.

See, I am a simple guy when it comes to handgun shooting. In general I feed them HP38, Red Dot, or if I want more I turn to AA9 or H110. On rare occasions I let a handgun get a diet of 2400 but that isn't very often.

 

[fiver]

heck 231 worked the same as red-dot, only it took a bit more to do the same thing.
I was thinking green-dot, or am.select or bulls-eye, or maybe even unique. [how about some alcan #5?]
somebody has to shoot this stuff..
I ain't walking in there to get a whole list...

you are shooting red-dot at what [4grs?] I'm at 3.2 with everything else practically the same.
my CZ does shoot a click low with that load though.

 

[Brad]

I may need to go lower in Red Dot. I have been running 3.5 to 4 gr. might need a little less powder. Mine tends to shoot a bit high.

AL5? Man, how old is that stuff?

 

[freebullet]

3.6-4gr of red dot is tops for me.

Hs6 gives better accuracy, but takes more and don't burn clean until you get to med- upper end of charges.

 

[fiver]

old enough I got data for it, some is on the side of the alcan wad boxes.
they are 'NOW lubed with graphite' fresh, but have no crush section to the wad.
you adjust the wad column height with the cardboard inserts they provide.
