pbosik Posted November 18, 2007 Share Posted November 18, 2007 well, just got my backup SP01, went and shot it all great, no jams,etc..picked up the brass and there is a huge buldge near the base of the case on all the brass,,took the slide off and it looks like the feed ramp was polished and that the barrel is throaued similiar to a 45 1911, on each side of the ramp and polished ..when u drop a round in the barrel it will fit good but there is the gap between barrel and brass at the throated area..i think this it where the case issue is coming from,,also the primers are flat like my open gun when the pressures were high..I am loading 3.4 clays, 135 zero @ 1.110 oal...the gun runs great, i dont care if the brass issue is all i have here. Anyone think there is something i need to be concerned about here??i would hate to have to get a new barrel.. Link to comment Share on other sites More sharing options...
eerw Posted November 18, 2007 Share Posted November 18, 2007 seems a bit extreme to me.. did you buy the gun used?? or is this from the factory?? Link to comment Share on other sites More sharing options...

get2now Posted November 18, 2007 Share Posted November 18, 2007 Looks like you should check the bullet diameter, chronograph your loads, and if that's okay you need a new barrel. Gary Link to comment Share on other sites More sharing options...
oddjob Posted November 18, 2007 Share Posted November 18, 2007 I'm with Gary on this..........I use a SP-01 and have never seen this.......Never Link to comment Share on other sites More sharing options...
G-ManBart Posted November 18, 2007 Share Posted November 18, 2007 Yikes I think that's beyond anything remotely considered normal....Much more and you'd be looking at ruptured cases. Link to comment Share on other sites More sharing options...
Dave Gundry Posted November 18, 2007 Share Posted November 18, 2007 FWIW, the SP01 I just picked up had a beautifully polished feed ramp right from the factory. It wasn't mirror shiny, but it was better than most of the other guns I've seen, and good enough to the point it wouldn't need any further attention...

shadetree Posted November 18, 2007 Share Posted November 18, 2007 That does not look good. I have not seen cz brass look like that before. Looks like those cases are just about to burst. If that's a new gun you should have it looked at. Link to comment Share on other sites More sharing options...
JThompson Posted November 18, 2007 Share Posted November 18, 2007 Looks pretty extreme to me.... I don't think I would be comfortable shooting that. Link to comment Share on other sites More sharing options...
boz1911 Posted November 18, 2007 Share Posted November 18, 2007 Chrono that ammo in something else. A new barrel is cheaper than a hospital visit and an entire new gun........Just my 2sense Link to comment Share on other sites More sharing options...
revchuck Posted November 18, 2007 Share Posted November 18, 2007 Time for a new barrel. CZ barrels are very good about feeding when stock, they don't need much more than touching up. They're also accurate, so you just need to get another factroy barrel instead of springing for a Bar-Sto or such. Link to comment Share on other sites More sharing options...
DougCarden Posted November 18, 2007 Share Posted November 18, 2007 CLAYS has a pressure spike, and with that short OAL I am not surprised. You have reached the tolerance and are just next to blowing cases with that load. CLAYS is great for minor loads, but with that short OAL you are mimicing(if that is a word....) the 147gr loads that people tried years ago with 147s had the same problem. If you want to load that short you will have to run a slower powder, like Titegroup, VV 320, Solo 1000, etc.. CLAYS is fine for minor loads with bullet weights up to 125gr, but running short OALs for the CZ you are asking for trouble with the CLAYS load....If you could load it out to 1.130 it might be doable... <speaking with the been there done that voice mode on....> I would try some factory ammo and some other loads before replacing the barrel to see if they bulge too......... Glad you paid attention and caught it....the mark of an experienced reloader..... Good luck, DougC Link to comment Share on other sites More sharing options...
eerw Posted November 18, 2007 Share Posted November 18, 2007 oh yeah..check that load. the clays load that I have for my SP01 3.5 with a 124jhp at 1.125 and that is a 130PF load. Link to comment Share on other sites More sharing options...
basman Posted November 18, 2007 Share Posted November 18, 2007 Try some factory ammo, if that bulges, send it back to CZ and include an example of the brass. 3.4 gr of Clays loaded at 1.155 OAL showed no pressure signs out of my M&P. and came in at 130 PF!

pbosik Posted November 18, 2007 Author Share Posted November 18, 2007 thanks for the input, I just bought this pistol from someone on uspsa web, he said he got it from Angus as the custom..I asked him about the brass and barrel issue..he said that is how he got it..he said he only shot aprox 700 rds thru it..I thought I was getting a god deal, but looks like I may have gotten the dreaded "wanker" instead. Somethink doesn't smell right here....Anyone know where I can get a barrel?. I went to czusa and did not see anything,likewise on Angus site?? btw- this load is chrono @ 130pf Link to comment Share on other sites More sharing options...
pbosik Posted November 18, 2007 Author Share Posted November 18, 2007 here is a couple of pics.. Link to comment Share on other sites More sharing options...
JThompson Posted November 18, 2007 Share Posted November 18, 2007 (edited) here is a couple of pics.. Angus is a good man... he will fix you up if need b e... in the mean time show us a picture with proper focus. If you are using an auto focus camera put your hand right, or something else, beside the barrel chamber and it will focus on your hand at the same point as the chamber. That way it will attain proper focus. Edited November 19, 2007 by JThompson Link to comment Share on other sites More sharing options...
Jaxshooter Posted November 18, 2007 Share Posted November 18, 2007 Looking at your picture it looks like half of the case is not supported. It may be the angle of the pic that makes it look like that much is unsupported. The bottom is unsupported for sure. If you are getting a pressure spike it is going to bulge or worse where it is not supported. It is hard to tell from the pic but it looks like the ramp is cut up into the chamber an flared out on the sides. Link to comment Share on other sites More sharing options...
Dave Gundry Posted November 18, 2007 Share Posted November 18, 2007 Need better focus, but from the looks of it - somebody might be guilty of DWI (dremeling while intoxicated)... Link to comment Share on other sites More sharing options...
pbosik Posted November 18, 2007 Author Share Posted November 18, 2007 DWI, I like that...I think you are right..but we have denial going on here..My pics suck , but there is the big gap at the bottom of the barrel..I will call Angus tomorrow for some help. I just can't imagine that crazy throating being done by him...ha, ha, dwi that was funny.... Link to comment Share on other sites More sharing options...
DougCarden Posted November 18, 2007 Share Posted November 18, 2007 Ummmm......did you try it with factory ammo yet? Angus will ask you that.... Link to comment Share on other sites More sharing options...
Carmoney Posted November 18, 2007 Share Posted November 18, 2007 Hold the phone. You guys keep telling him to shoot factory ammo in it, etc. I wouldn't advise that at all--factory ammo has plenty of pressure and this guy has a gun problem. High pressure handloads, even at the edge of creating a kaboom, would not leave that kind of frickin' bulge. That has to be lack of proper barrel support. I wouldn't shoot another round of anything through that barrel, period. Link to comment Share on other sites More sharing options...
Carmoney Posted November 18, 2007 Share Posted November 18, 2007 I just looked at the pictures again, and now I'm even more sure of it. Somebody over-throated it. Link to comment Share on other sites More sharing options...

Larry White Posted November 19, 2007 Share Posted November 19, 2007 (edited) What really sucks is that someone sold that pistol in that condition. I just cant believe the seller fired that pistol and didnt know it had a problem. That barrel and every piece of brass ever fired in it is trash.----------------Larry Edited November 19, 2007 by Larry White Link to comment Share on other sites More sharing options...
