New CZ75B feeding issues

[tcmass]

I've seen a number of topics on this since searching. Even with the same ammo I used. However, here is the issue at hand.

Picked up a 2012 production CZ75B and shot it this past Sunday. Shot 125 rounds of UMC and had 2 failures to feed in the middle of a magazine. I'm only slightly aggravated. 125 rounds is hardly a test of a firearm and with only one brand of ammo, but none the less.

I've ordered a 16lb spring from Wolff. I plan on shooting a fair number with the current spring, then switching to the new spring and see what happens in one range session.

Other then UMC being dirty as ever, is there something generally wrong with it? Underpowered, etc.

I've heard people reporting issues with UMC multiple times.  Pick up some different ammo and give it a shot this weekend.  Also, if you experience problems with the other ammo, keep track of which magazine(s) experience the problems.

Yes. It generally doesn't work well in a CZ. Try a different brand of ammo. I personally like Speer Lawman 124gr. $12.99 a box at Academy. If you don't mind ordering online I recommend Sellier & Bellot.

The only feed issues I have had have been due to my not firmly seating the magazine in the well.

I'll keep that in mind my next trip out. Jim, I plan on buying a few different brands to see what happens. Hopefully my local store will have some S&B for trials and I can place a bulk order online if it runs. I really want it to run with multiple brands though..

You should have no problems with most any other brand out there. I have used S&B, Monarch, Blazer Brass, Federal, Winchester, Speer, etc with no problems in any of my CZ's. I have never personally tried to use Remington UMC due to multiple complaints from other members here but I have used Remington ShurShot and it functioned well in my CZ's but not in my Ruger P95.

It seems to pretty much just be a problem with UMC.  Personally, I've never seen the appeal of UMC, as it doesn't seem to feed that well, it's very dirty, and at least around here it's more expensive than the other alternatives.  A box or UMC is usually $14 to $15 around here at the places that carry it, while Wally world has Federal and WWB for $10/50 every day.  I've also seen 124 gr. RWS ammo at Wally world at reasonable prices, which I liked so much I bought a few cases online.   Try different types of ammo and see if you don't have better luck.

I've never shot any UMC before in any caliber. So I didn't know what to expect. It was on a Sunday and the normal gun store I buy from is closed, so off to Walmart I went. 250 rounds for 60 bucks wasn't a steller deal, but if I wanted to shoot it was my best bet at the time.

Did you do a pre-shooting cleaning? I've sometimes heard that guns fresh from the factory can be a bit sticky with the lube they're shipped with.

Also, as others have said, try some other ammo. WWB and federal for the cheap stuff.

With only 125rds through a new CZ,  it's  not broken in yet.  Make sure it's thoroughly cleaned and well oiled, and shoot the heck out of it.  By 500 or more rds, it "might" start accepting the UMC ammo.  Dry fire and racking the slide also speeds up the break-in period.  Also,  keep the mags clean and dry.
As said above, a number of CZ shooters have had troubles with UMC---some not.

Friends use the Wal-Mart RWS ammo with good results.  Any other Wal-Mart bulk 9mm ammo seems to shoot fine.  Before I started reloading, Win White Box of 50 ran very smoothly in my 75B.

Personally, I wouldn't install a heavier recoil spring (or make any changes to the gun) until the gun is broken in.  The 14# stock spring should run typical range ammo and some heavier loads just fine.  Ejected Cases should "fly" about 6'-8'. 

Hope this makes sense.

FWIW---  My CZ75B shoots the S&B 115g very well ($12.99/50 at my AcademySports, also shoots AS's Monarch 9mm/115g ($11.99/50, which is actually PriviPartizan ammo made in Serbia and imported by Academy);
also shoot WWB 115g at the range without any mofo's. I've shot RWS also when I found it and consider RWS ammo GTG.

Have not tried UMC, Tula, nor Blazer, haven't felt the need to. Never shot any steel casings of any mfg.

For PD, I load Speer GoldDots and Federal Hydras, both feed well in mine.

In my mind, overall I like the S&B best for the range and steelmatch--goes BANGBANG everytime for me. Comforting.

Yes I did clean out the packing grease and oil normally.

I agree completely, 125 rounds is hardly a test. Who doesn't want their new firearm to run flawlessly out of the box though, haha.

FWIW---  My CZ75B shoots the S&B 115g very well ($12.99/50 at my AcademySports, also shoots AS's Monarch 9mm/115g ($11.99/50, which is actually PriviPartizan ammo made in Serbia and imported by Academy)...

S&B will be my first try then after you guys have had such great luck with it. I never knew that about Monarch..thanks for the info.

I appreciate you guys chiming in. I won't be able to shoot this weekend, but I should be able to go next week to an indoor range.

Sometimes the Extractor Groove Channel just ahead of the Case Rim is not well formed/shallow in the Brass Shell casing.
There may be other issues.

It's not just Cz's that sometimes have issues with Remington/UMC ammunition.  I see a lot of other handguns choke on it.
This seems to have been a regular trend during the last 6 years or so.

Some Pistols with a different Extractor design have no issues with it at all.  Notably, the Beretta/Taurus 92 series.

I've never had a problem with BVAC re manufactured ammo and you can't beat the price:http://www.cheaperthandirt.com/product/AMM-4212

Here's my .02 cents on this.  I have seen all to often, ammo that was out of spec.  For instance I have experienced failures to feed with WWB and upon inspection, found the case mouth was not crimped from the factory.  No semi-auto will feed a 9mm Parabellum w/o a taper crimp.  Not Glock, not Sig, no one.  Most folks don't even know 9mm ammo is not straight walled, it's tapered, which delivers greater feeding reliability.

So the moral of the story is, never base your pistols integrity on a single type of ammo.  Here's a shocker - premium ammo delivers exceptional performance.  What do most folks use - the cheapest ammo they can find.  And when there is a problem, they typically try to figure out what's wrong with their pistols.
