velo918 Posted February 14, 2014 Share Posted February 14, 2014 I don't reload but I have someone who does it for me, but I need to know what works in this gun. Anyone have any experience with reloading for the Czechmate? I can't seem to get a straight answer... Thanks! Link to comment Share on other sites More sharing options...
kneelingatlas Posted February 15, 2014 Share Posted February 15, 2014 I don't have a CM, but I made a custom Open gun from a TS so I should be able to help. What components do you have available to you? I have tested data for SP2 and HS6 with 100, 115, 124 and 135 grain bullets. Link to comment Share on other sites More sharing options...
velo918 Posted February 15, 2014 Author Share Posted February 15, 2014 Don't know powder but will be using Montana Gold 124 gr JHP bullet Link to comment Share on other sites More sharing options...
kneelingatlas Posted February 15, 2014 Share Posted February 15, 2014 JHP bullet Hmmm... that's going to be a problem. I find hollow points cannot load very long at all in my CZs (~1.1") and the shorter the round the higher the pressure. 124 is a good bullet, but a round nose bullet is what you need unless you ream the barrel. A RN loaded about 1.16" should be just right, I loaded some out to 1.185" but they had issues in the mags. Some powders to look for: HS6, SP2, Silhouette, Autocomp, 3N38 Link to comment Share on other sites More sharing options...
Unregistered Posted February 15, 2014 Share Posted February 15, 2014 Aren't you more limited by the mag dimensions for a cz? You may ream the chamber out, but I believe your mags would limit the OAL. Link to comment Share on other sites More sharing options...
kneelingatlas Posted February 15, 2014 Share Posted February 15, 2014 (edited) Aren't you more limited by the mag dimensions for a cz? You may ream the chamber out, but I believe your mags would limit the OAL. When you've loaded too long for the mag, it's the tip of the bullet which catches in the front of the mag so the bullet profile is irrelevant, a JHP @ 1.18" is just as likely to hang up in the mag as a CMJ @ 1.18", but it's the shoulder of the bullet which hits the rifling when your load is too long. The shoulder of a JHP is much closer to the tip than a CMJ so the same chamber might take a CMJ at 1.165" no problem, but choke on a JHP at 1.115". Does that make sense?

velo918 Posted February 15, 2014 Author Share Posted February 15, 2014 Sure does to me and what I've read is czechmates don't like hollow points Link to comment Share on other sites More sharing options...
kneelingatlas Posted February 15, 2014 Share Posted February 15, 2014 I shoot 115gr xtreme plated bullets and I have lots, I'll sell you a flat rate box full if you want to try some? Link to comment Share on other sites More sharing options...
velo918 Posted February 15, 2014 Author Share Posted February 15, 2014 Thanks for the offer, but I don't reload. I'm trying to order some from a couple of sources but I had no idea what to tell them. Looks like I'm going to have to ship my gun and have them try different loads. Link to comment Share on other sites More sharing options...
trgt Posted February 15, 2014 Share Posted February 15, 2014 (edited) I'm kind of in the same boat as you, I'm not loading my own 9mm major yet for my Czechmate. There's a few threads here and elsewhere where I ended up with this as a starting point: 115 - 124 bullet OAL: 1.165 max (1.17 too long)Auto comp: 7gr In general it seemed that anything longer than 1.13 would hit the rifling, but I haven't tested this rigorously against a lot of different profiles. A vendor here Blamtec is willing to load 9mm Major, but he wanted new brass for safety - I sent him Starline. He did work up a few different bullets/loads for me and my initial testing: Blamtech 115 MG FMJ, Autocomp 7.4, OAL 1.13 - 147 fps-> 169,000 Power FactorBlamtech 121 MG IFP, Autocomp 7.1, OAL 1.13 - 142.6 fps -> 173,000 Power FactorBlamtech 124 MG CMJ, Autocomp 6.9, OAL 1.13 - 140 fps -> 174,000 Power Factor I've been focusing on production, so haven't shot this a lot yet (his 9mm minor 124 and 147 nice in the production gun BTW). So this isn't tuned for best accuracy or keeping the muzzle flat yet - that's next! I have some other stuff to test/refine, when I have results I'll post.

gianmarko Posted February 17, 2014 Share Posted February 17, 2014 i have experimented some with the CM. at the end i got two barrels reamed so i can finally load at decent OAL. this has immediately lowered pressures and cases look much better now. 8.5 grains of SP2 will make factor and produce nice, comfortable loads with a 124 grains bullet. the CM has a pretty good compensator that doesnt require massive loads to work. i am also using a swiss powder that gives good results with around 7/7.2 grains i dont use lighter bullets as they are not legal in IPSC i have tested some bigger loads, up to PF 175 but no advantage and barrel flip increases the CM can use max OAL without problem as it is based on the tactical sport, magazines are different than the normal 75. i dont sort cases, could never see any difference in reliability and precision, and it is very time consuming. just tumble them, blow them with compressed air and lube them a little.

kneelingatlas Posted February 17, 2014 Share Posted February 17, 2014 The OAL makes a huge difference: at 1.137" it took just 7.7gr of SP2 to make 166PF but at 1.160" it took 8.2gr. Link to comment Share on other sites More sharing options...
Demented1 Posted February 18, 2014 Share Posted February 18, 2014 my son shoots a cm and we are doin major pf with 124g montana golds, 7.1g of silhouette and 1.15oal if im not mistaken. but i can double check tomorrow to be sure!! i have 3 sons and we all shoot open 9major but on different platforms so we all have different loads, we have berrys on the way and will try another load with them.

ConeKiller Posted February 20, 2014 Share Posted February 20, 2014 I'm running a Czechmate in Open right now and am loading (gun runs / cycles good for me at these loads): 124 gr MG CMJ 1.140 OAL 8.1 grains of HS6 I'm currently out of HS6 and had a couple small tubs of Autocomp.......so loading 6.8 grains of autocomp. I prefer HS6 over autocomp so far though, but can't find HS6 in stock anywhere. (~171 PF) Link to comment Share on other sites More sharing options...

Demented1 Posted April 6, 2014 Share Posted April 6, 2014 we got 170 and 172 avgs but we are having issueswith it cycling we just ordered lighter springs and will get it dialed in the next couple weeks. we are playing with autocomp, silhouette for powders. berrys and montana gold round nose for bullets, federal premium rifle primers, wolf rifle primers, cci rifle primers etc. sorry for late response we have been busy and i forgot i even posted lol my bad but i will make sure and document our findings these next couple weeks for everyone. we are getting ready for cowtown so we really need to get this dialed in.

Demented1 Posted April 6, 2014 Share Posted April 6, 2014 our last load was with silhouette 7.2. berrys 124 gr round nose with a federal primer we are using an oal of 1.140-1.145 this gave us 168 powerf actor but its not cycling the slide back enough to load another round Link to comment Share on other sites More sharing options...
Demented1 Posted April 25, 2014 Share Posted April 25, 2014 ok i think we have it finally. we had to go to autocomp powder 7.3g, montana gold 115 fmj, ccis mall pistol primers and 1.113 oal. we have it shooting smooth and cycling again. with silhouette we ended up runnin into issue where slide would not cycle. we are gonna chrony again tomorrow we brought our powder down from 7.5 because that has us at 1501avg of 3 shots and that 172 pf. tomorrow i will post numbers and then we will work on a load with 124 montana gold that i have coming. we also hadt o order an 8# wolf spring for it to get itt o work. we tried a 10# but still had some issues. either way im still workin om em and i hope this helps someone. theis has been a nightmaref or us, almost to a point where my son considered selling it.

gianmarko Posted May 10, 2014 Share Posted May 10, 2014 very odd to hear about a CM not cycling. mine cycles 9 out of 10 times with minor loads... works 100% reliably with commercial rounds. a friend has one, same results. Link to comment Share on other sites More sharing options...
