Baer45 Posted December 31, 2009 Share Posted December 31, 2009 Have done search. I was reading Sweeney's new book and saw a picture of a 9 mm case after being fired through an MP 5. My new MP-5 just came a month ago and I was thrilled as I have a Dillon S1050 set up just for 9 mm. When I looked at my fired cases they have the black marks left by the extractor but I do not have the significant "bend" marks in the brass like his picture shows. Patrick says the brass can only be reloaded once safely after being fired through an MP-5. Sweeney is my favorite writer of all time and I pretty much take what he says as the Gospel so I wondered if anyone else has had this experience and if so; if I Case Pro all my 9 mm can I keep reloading it? Any help appreciated- C Link to comment Share on other sites More sharing options...
-JQ- Posted December 31, 2009 Share Posted December 31, 2009 First Congrats on your purchase. The best weapon of all time I'm a fairly new reloader and hope to reload for my MP5 once I get my loading ironed out. Do you have load info to start with for the MP5? I have yet to find anything mine won't eat, however. But those have been strictly factory loads, Rem, WinWhiteBox, S&B, Magtech, American Eagle...etc. I haven't noticed the brass being too beat up on the 9mm...the 7.62 is a whole different look. I've read that even those can be reloaded some with work. I need to start loading 7.62 but...someday Anyone ? Link to comment Share on other sites More sharing options...
DougCarden Posted December 31, 2009 Share Posted December 31, 2009 The MP-5s are a closed bolt weapon, with a fluted chamber to help equalize the pressure in the chamber to help with extraction in combat conditions. Unless the loaded rounds were near max loads to begin with, tumble the brass and load it. We had some chinese ball ammo that gave me fits....I sorted through my batch and threw away everyone as they were max loads and not worth dicking with. Check it once you resize, and throw a couple in a case gauge to make sure the case rims arent too buggered up (which is what you would do with any other brass.....). I have been shooting "MP-5" brass and reloading it since 97 (armorer class) and find it no different than any other 9mm brass that you have to check over. Make sure you buy a couple spare extractors and extractor springs, and the roller bearing repair kit for the bolt, and you should be set for years of fun! Enjoy!

-JQ- Posted December 31, 2009 Share Posted December 31, 2009 Thanks Doug! That is just what I hoped to hear. i hope that helps brother Baer too +1 on the spares, too. I could use a tutorial on replacing the roller retainers Link to comment Share on other sites More sharing options...
jtielke Posted December 31, 2009 Share Posted December 31, 2009 The range I practice at held an MP-5 class last year. They left a ton of once fired 9mm brass on the ground and I picked a lot of it up. I've reloaded it several times, can still tell which by the flute marks. Haven't had a problem with it yet.

Intel6 Posted December 31, 2009 Share Posted December 31, 2009 It may not look pretty but it will work. There are lots of people out there who will tell you it can't be done, not sure what they base their opinion on. I have had a HK91 in 7.62 for some time and I have reloaded those cases over and over and other than being a bit dirty looking they work fine. I did a test just because of this "myth" and reloaded a WCC case 7 times before stopping. The only reason I stopped because the ejector system on the HK91 beats up the head of the case pretty well and I figured 7x reloading was a good test. I have reloaded lots of different types of fluted cases: 9mm from my P7M13 and various HK94/MP5 40 from the HK UMP that the Border Patrol use around here. 10mm fromt he local FBI MP5's 5.45 from HK 93/HK53 7.62 from my HK91 All of them have been reloaded and fired without any issues. The olny thing I have found I need to do differently is to run them longer in the cleaner to get off more of the carbon stain. Neal in AZ Link to comment Share on other sites More sharing options...
Baer45 Posted December 31, 2009 Author Share Posted December 31, 2009 Boy- this is of a great help to me! On reloading for the gun; a fairly well known writer who does the reloading section in a magazine we all read (my mind has gone blank) has shot 124 gr. Laser Cast over HP-38 for years in his SMG's with good results...I don"t know how lead will do when the papers come for my can but I am not too worried about finding a good load...

DougCarden Posted December 31, 2009 Share Posted December 31, 2009 Please dont run lead through the can, you wont be happy....... I would just buy 115fmj by the case from Montana Gold, or wherever you can get the best deal in bulk. Run a medium powder like 231 or Power pistol and you should be a happy camper!

G-ManBart Posted January 1, 2010 Share Posted January 1, 2010 The MP-5/10 does seem to be a bit harder on brass than the 9mm versions.....lots of split cases. Some guns are clearly worse about that than others, but if the cases don't split, you can normally get decent use out of them. R, Link to comment Share on other sites More sharing options...

Some guns are clearly worse about that than others, but if the cases don't split, you can normally get decent use out of them. R, I would find a case split on one of the flute lines every so often. After cleaning I would look for that and weed out any bad ones. After that it is great brass for my 610 Neal in AZ Edited January 3, 2010 by Intel6 Link to comment Share on other sites More sharing options...
Baer45 Posted January 1, 2010 Author Share Posted January 1, 2010 Neil- Thanks for your input, a big help as this is my first SMG. Do you have a favorite load for your MP5 in 9mm? I was going to go with the LC 124 over HP-38 and then use Berry's when I put a can on....CS in Dublin, Va. PS- I think Doug gave me the answer...but if I can get load info for what works in someone else's MP5 such as OAL, etc. it would save me some time...

SBR7_11 Posted January 4, 2010 Share Posted January 4, 2010 Just for fun -- Run them 9mm HK empties through a size die (clean the cases first) and load as usual. Link to comment Share on other sites More sharing options...

Baer45 Posted February 1, 2010 Author Share Posted February 1, 2010 No lead through the can so I guess I will load the cheapest plated I can find. I think there is a local manufacturer around here somewhere...unless someone has another idea.... Link to comment Share on other sites More sharing options...
Carlos Posted February 1, 2010 Share Posted February 1, 2010 I received a partial bucket of MP-5'd cases from an LEO trainer buddy. Although they were once-fired, I got "scurred" of the lines & palpable ridges left by the chamber so I gave them away to a friend who shoots 9major out of his STI. He reported NO problems at all with these cases & all were loaded to major. I'd use such cases in the future without hesitation. The MP-5s are a closed bolt weapon, with a fluted chamber to help equalize the pressure in the chamber to help with extraction in combat conditions. Unless the loaded rounds were near max loads to begin with, tumble the brass and load it.

jmorris Posted February 1, 2010 Share Posted February 1, 2010 I have had no problems with brass shot in fluted chambers. FWIW The Schumann AET pistol barrels are also fluted. +1 on the no lead in a suppressor. I have used my 9mm minor load of Berry’s 147 with 3.1 of VVN310 1.160” in MP5’s and Mac’s. It works great in everything except the ported MP5SD. I also substitute 3.2-3.4 grains of Titegroup to save money when I’m loading up a bunch of hosing ammo.

Big Bore Posted February 1, 2010 Share Posted February 1, 2010 I run 10 mm brass that has been through a MP5-10 with out any problems. I occasinaly find one that is split. I do not load them NORMA hot but I push 200 grains at 950fps with out any issues. Link to comment Share on other sites More sharing options...
JimmyZip Posted February 1, 2010 Share Posted February 1, 2010 The overwhelming majority of brass I shot last year was 9mm and .40S&W that was fired through fluted chamber subguns. It was free, so I couldn't pass it up. With the highway patrol and sherrifs office using our range monthly, there is no small supply. I could theoretically shoot nothing but if I wanted to as there is just so much of it. It is generally Blazer or Federal so there is no need to sort by headstamp. (One caliber is one, the other is the other) It gives me comfort to know that our range will always supply me with enough brass to really last me indefinitely. Now if your into casting, you're just as lucky. Casters at our range report it is the easiest place to get lead, and that they don't even have to dig, just pick it off the top. Life is good.JZ Link to comment Share on other sites More sharing options...
DyNo! Posted February 1, 2010 Share Posted February 1, 2010 Fluted brass will fail sooner but it is good to reload. I don't even bother picking up the brass from my 53&33. I try to make it where my brass goes to die. Link to comment Share on other sites More sharing options...
Patrick Sweeney Posted February 1, 2010 Share Posted February 1, 2010 OK, learn (or-re-learn) something new every day. The brass I tested came from MP5s being fed LEO-only +P and +P+ ammo. Clearly, that brass was being hammered a lot harder than the stuff you guys see. (Maybe the guns were a bit tired, too.) I'll make a mental note that my experience was apparently not the norm. MP5; a nice, 10-pound handgun. And the only SMG I've ever broken. Link to comment Share on other sites More sharing options...
-JQ- Posted February 1, 2010 Share Posted February 1, 2010 And the only SMG I've ever broken. OT: how did you do that? Link to comment Share on other sites More sharing options...
Patrick Sweeney Posted February 4, 2010 Share Posted February 4, 2010 In an LEO operators/armorers class. The hammer snapped off at the base on the range, during test-fire. In all fairness, the guys who had shot the million rounds through it before I got there probably did all the hard work. Link to comment Share on other sites More sharing options...
