kcin Posted December 27, 2019 Share Posted December 27, 2019 Can anyone tell me what the maximum OAL for a CZ TSO in .40 cal? Sorry if this question has been answer multiple times already. I tried searching for the answer but came up empty. Link to comment Share on other sites More sharing options...

I tried searching for the answer but came up empty. CZ are notoriously short chambered. You can ream the chamber to accept longer length bullets (as long as your magazines allow) but you will have to follow factory length which is 1.135 OALSent from my SM-N960U using Tapatalk Link to comment Share on other sites More sharing options...

iflyskyhigh Posted December 27, 2019 Share Posted December 27, 2019 1.135 is what I came up with. I could get 1.140 to plunk most of the time but with a dirty barrel and the occasional “just a little too long” round failing to plunk, wasn’t worth it for the extra .005. Plus 1.135 is just about the max for the TSO magazine as stated. I’m not serious enough about the sport or any one class in particular to spend the time or money to customize, so I just shoot as is for fun.

Never say never, but I’m pretty sure they will not. Too long for the gun, too long for the magazine. Edit* Just read that post an apparently people have done it. Guess I should be more specific and say my stock pistol will not. Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...

How the heck did he get a 1.160” round to chamber???? He must have a reemed barrel????And I tried to to load a magazine full of 1.150” and they were borderline rubbing the front of the magazine. I didn’t try, but I don’t think I could get a mag full of 1.160”. I guess it’s pointless to try since I’m capped at 1.135” by the barrel.

I don know that different profile bullets stack differently in the mag. my 200gr RN would rub at the same length my 180 RNFP would be fine. That said i load to 1.130 and it works fine for me. No issues removing a chambered round. Maybe ill check when i get home for poops and grins. Link to comment Share on other sites More sharing options...

A friend with a Czechmate had to have the throat reamed so he could run 1.160". If you try it you may end up setting back the bullet and raising pressure a lot. Before I bought mine, several friend who had them told me that if I loaded to 1.126" I'd never have a feeding problem no matter what the bullet profile. They were right. The standard 1.135" failed to reliably feed some profiles. Link to comment Share on other sites More sharing options...
regor Posted December 28, 2019 Share Posted December 28, 2019 Max OAL will be very dependent on projectile choice. With Gallant 180s I can load to 1.165 and plunk, but I had 2-3/100 that would fully chamber but not drop freely (they went into a practice box and I never had any issues with them in practice). I shortened to 1.15 and that issue went away and I no longer feel like the noses are rubbing inside the magazine. 1.17 is about the max OAL the mags can handle before rounds will bind. I bought my TSO used but I’m pretty sure it was not reamed. Link to comment Share on other sites More sharing options...
aandabooks Posted December 28, 2019 Share Posted December 28, 2019 I run S&S RN 200gr at 1.180" and have no problems. Barrels are not reamed as I use them in both a TS and TSO. I'll have to measure some of my 180gr loads since I haven't loaded any of them in a couple years since switching to the 200gr bullets. Link to comment Share on other sites More sharing options...
obsessiveshooter Posted December 28, 2019 Share Posted December 28, 2019 Why load long, if it runs perfect at factory length? I load my TS to 1.135 and have ZERO issues. It FTFs on some long loaded ammo though. Sent from my SM-N960U using Tapatalk Link to comment Share on other sites More sharing options...
Superkaratemonkeyfighter Posted December 28, 2019 Share Posted December 28, 2019 1.130 going much longer might open up magazine issues. Link to comment Share on other sites More sharing options...
858 Posted December 29, 2019 Share Posted December 29, 2019 The TS/TSO does not have a short throat like the Shadows. Depending on the bullet, you max overall length should be the ejection port length. Link to comment Share on other sites More sharing options...
Riley Posted December 29, 2019 Share Posted December 29, 2019 I load at 1.130 with a 180gr Blue Bullet, much longer and it won’t feed reliably. Over about 1.145 and a loaded round doesn’t eject well. Link to comment Share on other sites More sharing options...

Its my understanding the the coating on the CZ barrels is too hard to ream or at least it is on the shadow2. Link to comment Share on other sites More sharing options...

aandabooks Posted December 31, 2019 Share Posted December 31, 2019 I bought a HSS reamer from Brownells a couple years ago and have reamed several barrels with it. Have also loaned it out to friends. Have never had a problem reaming any barrel except one 9mm barrel from Springfield in a 9mm Loaded model. I have my Czechmate and TS barrels able to load out to 1.170" with no problem.
