chowellacsbd Posted January 14, 2011 Share Posted January 14, 2011 Planning an IPSC/Steel Open build for 9mm major and would like to know if anyone can help me providing pros/cons for either brand. Planning to use 9mm govt length. Not sure if it's relevant, but gunsmith will be threading for comp. Link to comment Share on other sites More sharing options...
Pro2AInPA Posted January 14, 2011 Share Posted January 14, 2011 (edited) I'm not sure that either is really better than the other. What I can tell you is that my open gun (also a full size 9 major) has a Scheumann AET barrel, and I have no complaints. My ammo drops into the chamber easily and I've had no sticky extraction issues or anything. I'm making major comfortably with 8.1gr of HS-6 under a 124gr CMJ, while some other people I've talked to are running 8.3gr for the same PF, so maybe the Scheumanns are fast barrels? I don't think you'll run into problems whichever way you decide to go. Edited January 14, 2011 by Pro2AInPA Link to comment Share on other sites More sharing options...

CocoBolo Posted January 14, 2011 Share Posted January 14, 2011 6 Open Gun barrels 4 Clarks, 1 Schuemann, and a STI. The Clark's are always faster. 175pf with 7.4gr of Silhouette SPM 124gr RN MTG 1.165. New M5 1/2" Schueman Ultimatch bull against a 5" Clark bushing w/1200 rds on it the Schuemann lost the speed contest by 8 fps avg. I have been impressed with the Accuracy of the Clark as well. All of them run extract etc. The Schueman is a 1/32 but have not verifed accuracy yet for it. Clark Custom Guns has provided good service, cut, crown, thread etc and very nomimal prices.

Planning to use 9mm govt length. Not sure if it's relevant, but gunsmith will be threading for comp. Schuemann is great barrel. KKM is a great barrel. Differences: KKM will cost you less to buy. KKM will require more labor to fit. Only your gunsmith can say which is going to cost you less to install. KKM barrels are faster than than Schuemann. By faster I mean the same load in each barrel will chrono faster in KKM So you could use less powder to acheive the same PF in a KKM, thus saving you a few more pennies.

G-ManBart Posted January 15, 2011 Share Posted January 15, 2011 Full disclosure, I'm sponsored by Schuemann, but I would absolutely pay for them if I wasn't...without a second thought. KKM was started by a former Schuemann employee. They are essentially the last version of Schuemann technology. They are made much more oversized and take longer to fit, so you wind up paying more for gunsmith labor. I've had no less than three top smiths tell me that in the end, buying the more expensive Schuemann winds up being either the same, or a tick less in overall cost. I've got Open guns with Bar-Sto, KKM, Nowlin and Schuemann. The Schuemann is the most accurate, hands down. the last time I shot groups at 25yds, I shot several 10-shot groups in a row that were at 1", and that was using a folded towel on top of my range bag for a rest. The AET versions will almost always require a bit more powder to get the same velocity, but that's the nature of gain twist rifling. The AET chamber aids extraction (it's biggest benefit IMO)...take the same gun, with the same springs, and swap from a standard to AET, and the cases from the AET barrel will fly about 3ft farther. The feed ramp is also mildly curved on the AET barrels, and that makes them feed incredibly smoothly. I did a video on table starts a while back, and in a follow up, used empty cases to clarify a point someone asked about...it fed empty cases when hand cycled. Don't take my word on it: http://www.brianenos.com/forums/index.php?showtopic=57882&view=findpost&p=672537 I've been doing some chrono and accuracy work with my .40 SS gun lately (it has an AET Classic). Using the same sort of rest as above, I shot three or four 1.25" or smaller groups at 25yds...it's scary accurate, and will feed anything (including empty cases) you put through it...not many .40 SS guns can say that.

GentlemanJim Posted January 15, 2011 Share Posted January 15, 2011 The Schuemann is the better choice IMHO But I have had very good results with STI as well Both outshot my KKM The customer service is great with both as well Jim Link to comment Share on other sites More sharing options...
Aircooled6racer Posted January 17, 2011 Share Posted January 17, 2011 Hello: The only issues I've heard and seen with the KKM's is that you either get a good one or a bad one. My open 9mm shorty had a great very accurate KKM in it when I bought it. I have seen a couple of other KKM's that had very bad inaccurate barrels that wore out very quickly. I like the Schuemann barrels since they are easier to fit and also have a great finsh to them. The accuracy has been very good with the ones I have(6 so far). I am not sponsored by Schuemann and I am still waiting for a barrel I ordered back in November. I know Mike has had some machine problems and is getting caught up now. I have a Briley barrel I am going to try next in a 45 build. The STI barrel is very good as well. I have a Tru-Bor series 2 barrel/comp that is a tack driver. Thanks, Eric Link to comment Share on other sites More sharing options...
BoldasLions Posted March 24, 2011 Share Posted March 24, 2011 It's my opinion Schuemann are best. Mike is a really good guy and loads of R&D is put into getting you the best barrel possible! Link to comment Share on other sites More sharing options...
Hannu Posted March 24, 2011 Share Posted March 24, 2011 Easier fitting but poor bore quality = Schuemann Better bore quality but takes more time to fit properly = KKM This opinion is based on new barrels I have seen / fitted within last 1 year.

Big Guy Posted March 25, 2011 Share Posted March 25, 2011 Had the same dilemma last year and learned the hard expensive way that KKM is not the way to go. Had lots of problems with tumbling bullets until I replace the barrel. Will not recommend a KKM barrel to anyone. Link to comment Share on other sites More sharing options...

Will not recommend a KKM barrel to anyone. first time i heard that kkm barrel would make your bullet tumble. they are very accurate barrels for me. it outshot my ultimatch barrel, both in 40 cal Link to comment Share on other sites More sharing options...
Rambo Posted January 24, 2013 Share Posted January 24, 2013 I would ask your gunsmith if he has a preference. Yes, it's your gun and I'm sure he would make it how you want. BUT I believe part of the pricetag is paying for the gunsmiths knowledge and expertise. Plus he's the one that has to fit it, etc... Link to comment Share on other sites More sharing options...
Jaxshooter Posted January 24, 2013 Share Posted January 24, 2013 I have a KKM and Schuemann barrels and there is no difference in accuracy between them. I will also agree that Clark barrels are as good as it gets. Link to comment Share on other sites More sharing options...

Rob HESS Posted January 30, 2013 Share Posted January 30, 2013 Schuemann makes a fantastic barrel. Call Mike and talk to him. He is a wealth of knowledge and he will give you the technical and practical differences. He is also a shooter. I have seen a pro shooter shoot a 10" steel target at 97 yards with MIke's Colt officer with a Schuemann barrel in it. Not once but twice. It was extremely impressive. I have 3 of his barrels and they are very accurate and the quality is top notch. I also have a KKM in my glock. Though good, quality didn't compare. My 2 cents for what it is worth. You need to be comfortable. Link to comment Share on other sites More sharing options...

MoNsTeR Posted March 31, 2013 Share Posted March 31, 2013 i burned a KKM out in ~20k rounds. It seemed like a fine barrel... until it wasn't. I doubt I'll use KKM again. FWIW I replaced it with an SV. Link to comment Share on other sites More sharing options...
