Loads for a CZ

[Alstep]

I'm getting a 9mm CZ 75. Anybody have a favorite boolit & load that shoots well in that pistol?
Sure would appreciate your recommendations. Thanks.

Cast WW's from a Lee 356-120TC 6-banger mold lube/sized to .3575" through a Star using Tac#1 over 4.2gn HP-38 seated so that the plunk test passes. The CZ pistols have a short leade so just a sliver of the parallel part of the CB is visable above the case for my pistols. I use a taper crimp die to just remove the belling and I seat and crimp in 2 steps/stations. YMMV

I have a CZ 75 B Omega. The bore slugged at .3565. I had to use a .358 cast bullet to get it to stabilize. The leade on my barrel was .006". Any .358 cast bullet I tried hit the rifling and and lead would accumulate at the front of the chamber and after about 40 rounds the slide would not go into full battery.
I could use a jacketed bullet with no problems. To shoot cast I sent my barrel to dougguy and had the chamber reamed. I found excellent accuracy with 4756 powder( no longer available) and WW231 with a 125g. cast bullet.

My CZ 75B likes boolits sized .358. My favorite load is Blue Dot 6.0 gr. under the Lyman 358242 or 356402 @ 1075 fps. The Lee 356-120-TC and 356-125-2R are also winners. WSF 4.2 gr is also outstanding with these boolits. Use the COAL spec'd int he Lyman Handbook.

358242, 356402 and NOE 135 gr all with 4 gr AA2.

I have the CZ-75 Compact. It is the most accurate 9mm handgun that I own.

I use basically 3 loads. The first is a 115gr FMJ with 4.8gr of Bullseye. This is a maximum load, in my opinion, but it works in every gun I have tried it in. When I could not get FMJ bullets a few years ago, I bought a bunch of 115gr plated bullets. They were not nearly as accurate as the first load. I eventually reduced it to 4.4gr of Bullseye with that bullet to get the accuracy up to acceptable levels. It worked the CZ action (and most of my other guns), but not in all of the 9mm's I own.

From the beginning and during this time, I tried plain-base cast bullets. No luck with 3 or 4 moulds, different hardnesses, different powders, different amounts of powder, and different diameters up to 0.358". Eventually, I bought an RCBS 9mm mould with a gas check. Almost no problems with getting it to shoot. I use it interchangeably with the plated bullets, same powder and amount.

I have a CZ 75B and wanted to shoot cast with it but experienced some of the same problems as Harry O. I decided to load the CZ with 147 gr. (actual weight 154 gr.) cast bullets and try to duplicate the approximate velocity/energy as a .38 Spcl. My reasoning is that the .38 is very cast bullet friendly and if I could slow the velocity and reduce the pressure in the 9MM it should work as well. I tried to size to .358 but had chambering problems so I settled on .357 sizing and loaded the Accurate bullet over 3.0 gr. of Bullseye. This load clocks 871 fps with 259 ft/# of energy. Close enough to a .38 for me. This has proven to be an accurate load in my pistol and it doesn't lead.

Hmm, that is weird. Back in the days I was able to overcome the problems and made my CZ shoot also the Lee 124 tumble lube -design.

That's why a 6-hole Lee TL is what I would recommend (unless OP has a Star or other fast way to lube the bullets). I mean, with 9 mm you need to make it easy and fast.

1. clean the barrel BEFORE you start shooting lead. Take out all the copper etc.
2. Expand the case mouth enough before seating the bullet
3. moderate crimp is enough. When SEATING AND CRIMPING at the same time, make sure the mouth of the case does NOT scrape the surface of the bullet and form a thin lead ring in front of the case. Use you fingernail and if the ring is there, it will fall off. If it happens, you are crimping too much.
4. Cartridge overall length might sometimes be critical. If necessary, make it as long as the magazine accepts.
5. I haven't noticed big differences between powders in regard of the burning rate. In my experience if a 9 mm load leads, the powder is not the no. 1 issue.
6. use moderate loads. Sometimes the max load works just fine too.

lee trunicated cone non tumble lube mold 9mm bullet and w231 4.0 start load to 4.5 i have exellent accuracy and a light recoil with 4.o gr w231 powder and accuracy is a fist size group at 50 yds with my cz75b pistol
a fine shooting gun

For IDPA my CZ's are at their best running 4.1 gr of 231 under the 356402 bullets sized .357. This load works in all my 9MM pistols.

Thanks everyone for your input. Looks like I can't go wrong with 356402 or Lee TC boolit. Will have to order one of those. Local dealer is holding the CZ till I see the judge to put it on my license. People's Republic of NY.

Picked up my CZ last week and ran a few rounds through it. One nice shooting pistol. Point of aim, point of impact, a nice knot at 25 yds with factory FMJ ball ammo. No sight adjustment needed. Time to order moulds.

I use a 125 gr truncated cone bullet for IDPA and find it very accurate. The Lyman 356402. Any bullet of similar design should shoot well in your gun. The CZ is a very good design as you will find out. The load I use is 4.1 gr of 231 under the bullet sized .357.

I'm using a home cast 147 grain round nose sized 358 though the little gun does 357 just as well. Since I'm sitting on plenty of Promo I use 3.5 grains.

[runfiverun]

my 75B does just fine with the HM-2 130gr rnfp designed for the 9mm's with short throats.
3 grs of bulls-eye or red-dot functions the 9's I have 100% of the time every time.
the bulls-eye load drops the brass about 3 feet to my right in a nice tidy pile the red-dot is a click more energetic throwing them about 4 feet and a little more to the back.
they both shoot right behind the big green dot on the font sight from 10 yds to 25 yds or so.

Thanks to all who responded. Now another question. I'm looking for a kydex holster for IDPA, can't find any makers that list one specifically for a 75B. They have something for other models, but don't know if they will fit. Suggestions please!!!

I have both Blade Tech and Comp Tac kydex holsters for my CZ's. Both companies make excellent Kydex holsters that meet IDPA rules specifications. Buying either along with double mag pouches will serve you well for as long as you are capable of playing.
