reloading 9mm expander & crimper

[bozo699]

The bullet just goes into the case ever so slightly but enough that I can set the bullet straight in the case and it'll stay there. When I seat the bullet, it slides in very clean with no sense of binding or shaving. When its seated, it looks perfect. I will be working up loads for my CZ 75 P-01 with multiple barrels, CZ Custom, Barstow Barrels and the CZ factory barrel. I am using a single stage loader, being very meticulous with every round. Looking for the tightest group, 5 shot @25yards. The stock CZ barrel that came with the pistol 4.22" has so far beaten all the others, even the Barstow 5" barrel, bringing in a 7/8" 5 shot group @25yards. Hoping to get one of the (6) barrels to produce about 1/2" @ 25 yards. I am thinking that if I can seat the bullet without expanding and crimping, that is two more steps eliminated as far as not being the same with each reload. I thank you for your reply, it is very helpful. Richard

Richard,
The Cz barrels I have are factory barrels , plunk test on a Gauge will pass but not on the barrel itself so I suggest you load oal by using your barrel not a case gauge. I also load on a 550 and I set my tapered crimp just enough to pass the plunk. Remember they headspace off the mouth so too much crimp is undesirable I also use minimal chamfer for same reasons. I think on a single stage you can get by doing as you described

I just re-realized that you are shooting the 147gr XTP and was wondering how long you can load that in your CZ's? Normally they have a very short leade and you typically can't load heavy for caliber bullets.

Cheers,
Toby

Both my cz’s have short leads the TS2 shorter than the shadow 2 compact but both are short. I have loaded 147’s but have to seat deeper so of course reduce load and work up slowly so far I have not had any issues but found they both like 115’s and 124’s much better than the heavies for some reason.

So you can get by without 2 extra steps.

You can drive without a license, but how long until that bites you in the.....

Well the CGW barrel bushing may not improve your P01 Omega with the accuracy you are already getting. It also doesn't apparently work with threaded barrels. I'm shocked the P01 Omega is better than the Shadow 2 Target! Those are hand fit components on the Target model, hand fit at CZ. I assume everything is tighter on the target model vs the P01 Omega.

It just goes to show there are so many variables that go into shooting consistent and accurate. How the firearm fits you, is one of those variables and I assume the P01 Omega fits like a glove.

Here is a link to the CGW bushing: https://cajungunworks.com/product/barrel-bushing-sp-01-10x/

Personally, I wouldn't touch the P01 Omega if it was shooting that well in my hands.

Cheers,

I shot a bunch of rounds thru the TARGET CZ then grouped it and was shocked at how bad they were. Long story short, I sent it back to CZ. they did their thing and sent it back to me.... still groups the same. I figure if the groups out of the P-01 are 7/8" with factory loads, reloading should shave some off. Then it will be good enough to command space in my house.

I haven't gotten to that point yet. Still trying to get the reloading all together, thus the original question.

Hi, I'm not looking at that thru the eyes of skipping 2 steps to make things faster. I am meticulous with every single ammo round. I look at it thinking, the key to tight groups is consistency in every round. So I am thinking that eliminating the two steps, eliminates two more times you are messing with the case to cause inconsistencies in the ammo. Thus the original question. Thanks. Richard

The CGW bushing might be something I will be interested in. Not all of the contenders (barrels) are threaded. photo +2

Thanks Wayne, I appreciate your input. Richard

do I really need to expand and crimp

All depends on the brand of brass used & size of the chamber.

The 147 gr bullets cause the most problems for handloaders. The boatail helps to reduce problems.

I load up everything from 90gr Sig V-Crown through 147gr Hornady XTP.
I also load for different weights of Missouri lead bullets.

For my pistol rounds (5 different cartridges) I use the Lee 4 die sets.

I've noticed that with the heavier, longer bullets, they sometimes create a bulge when seating. The bullet not being exactly aligned before being pressed into the casing.
The Lee crimp die helps "iron" it out some, so to speak.

As I could end up carrying with any of the ammo I make, I put a crimp on everything.
Don't need that one in a million chance of anything happening when faced with a SHTF situation.

What "problems" do the 147 g bullets cause? I thought the boat tail was to reduce drag and thereby aid in accuracy. Thanks for your reply, Richard

This test with 163 gr lswc, sized to .356" shows rub marks on the brass from chambering in my Taurus G3C, 9mm.
Some brass works, most dont.

Used HS-6 powder to test fire. Not Recomended.

9mm 147 gr Bullets​

When seated deep into the tapered brass, a bulge may be produced. This may effect chambering & ejection of the rounds. Hollow points with longer bearing surfaces, may bulge more & raise pressures?

 

[std7mag]

So with the daughter bugging me for 9mm ammo, I decided to load some today.
Ok, for me too.
And some 45ACP.

Then I thought of something....

After running a casing through the sizing die, I tried to set a bullet in to see if it would clear.
None of the bullets that I have will sit into the casing after sizing.
9mm, 45ACP, 38SPCL, 357Mag, 45 Colt.
None of the different weights/styles. Jacketed or lead.

And no, it's not a set-up issue. They are all straight walled cartridges.

Im going to guess that you dont recommend HS6 due to how dirty it is? Just a guess

What velocity are you getting with the cast swc and in what gun? Good looking round

Try one of the Hornady 147g XTP HP. Thus my original question. Richard

Dont load my bullet. HS-6 ok.

No chronograph. Sold it in the 1970? Sky screens were the new thing then. Old ones used a cardboard with a copper wire running thru it. 1 for start, other for stop.
