Suches Posted July 17, 2004 Share Posted July 17, 2004 I'm loading fired brass in 9mm in a 550B. Occasionally, I load a round that when cycled (in a match, of course) won't feed because the casing is too wide near the base. Some of these loads I've pulled, and reloaded the case. They'll feed after the first stage (sized and primed), but not after seating the bullet (stage three). Am I hallucinating, or can the seating process cause the base of the case to bulge?

Kingman Posted July 17, 2004 Share Posted July 17, 2004 Well, what I am doing is buying once fired and then dumping it after I fire it once. Could be they were fired out of a glock. I have heard some problems with this. The remedy being the egw sizing die. Link to comment Share on other sites More sharing options...
Chriss Grube Posted July 17, 2004 Share Posted July 17, 2004 The Glock brass problem is in .40. What Bullet, case and dies are you using? Link to comment Share on other sites More sharing options...
EricW Posted July 17, 2004 Share Posted July 17, 2004 Guppy-bellied brass can happen in 9 too. Grind down your sizing die about .020 to .040" then make sure it's ALL the way down in your press. I mean ALL the way. As in if you go 1/16 of a turn more the ram cams on the die. If that fails, call EGW and see if they'll make you a 9mm small base die.

Garrett Posted July 17, 2004 Share Posted July 17, 2004 Occasionally, I load a round that when cycled (in a match, of course) won't feed because the casing is too wide near the base. You do run your match ammo through a case gauge, right? As Kingman said, get a U-die from EGW. It'll help. Link to comment Share on other sites More sharing options...
Rob Boudrie Posted July 17, 2004 Share Posted July 17, 2004 I've found the Case Pro to be abbsolutely wonderful for improving the quality of match ammo in both Super and 40 S&W. Other approaches also help, but the Case Pro is the ideal solution since it "rolls" the case back into shape, and does not tend to scrunch the brass towards the head. Also, the Case Pro people are wonderful to deal with. Link to comment Share on other sites More sharing options...
Kingman Posted July 17, 2004 Share Posted July 17, 2004 Case Pro? what is that. I have heard of the EGW U die but never case pro. Fill me in. Link to comment Share on other sites More sharing options...
Too_Slow Posted July 17, 2004 Share Posted July 17, 2004 Kingman The CasePro100 is a roll sizer. It is a special type of case sizer that rolls the case between two flat steel dies that reforms the case from the base up. They are not cheap but they do a very good job. You still have to use a regular sizer die in the press but it takes out the belly that forms in cases shot in an unsuported barrel. You can read more about the unit at http://www.casepro.net . I dont have one myself but I do have friends with them that I can use for both 40 S&W and 38 Super. Link to comment Share on other sites More sharing options...
Kingman Posted July 17, 2004 Share Posted July 17, 2004 thanks. Buying once fired 9mm brass. I am sure I will get some from glocks. Loading on an sdb so can't use the egw undersize die unless I set up a single stage just for that. Link to comment Share on other sites More sharing options...
EricW Posted July 17, 2004 Share Posted July 17, 2004 I'm not going to deny that the Casepro is simply wunderbar. I will say that you can solve 99.9% of guppy-bellied brass problems by judicious use of a bench grinder on your stock die - especially on the Dillon die. Best of all, as long as you have a grinder handy, the solution is $477 less than the Casepro. Link to comment Share on other sites More sharing options...
Kingman Posted July 17, 2004 Share Posted July 17, 2004 Eric, What do you do with a square deal die setup. its not the typical die threaded into the block. Or is the way they are setup better for that type of problem. Yeh noticed the price the u die is a whole lot cheaper and I have a couple old single stage presses around.

EricW Posted July 17, 2004 Share Posted July 17, 2004 The SDB dies are threaded are they not? If so, you can do exactly the same thing. If not, I would promptly ditch the SDB for a 550. Just my politically incorrect not so humble opinion....as usual. Link to comment Share on other sites More sharing options...
Kingman Posted July 18, 2004 Share Posted July 18, 2004 They are, just need to remember how to adjust them. The sizing part is a piece of steel that sits inside the toolhead then get tightened onto it. Will have to look really carefully at that. Link to comment Share on other sites More sharing options...
Chriss Grube Posted July 18, 2004 Share Posted July 18, 2004 I've had the Crock brass problem in .40 but never 9mm. Get a LEE FCD (Factory crimp die) Don't try to seat and crimp in one station. I use the Standard Dillon dies in my 650 and the FCD and they run fine. Only problem I had was with Star bullets that were FUBAR. They were not round and caused a bulge. Switched to Zero's and no more problems. Link to comment Share on other sites More sharing options...
texasag93 Posted July 18, 2004 Share Posted July 18, 2004 A Lee Factory crimp die will take those little "imperfections" out of all your loads. I love mine in 40. I shoot alot of once fired Glock brass. It is a life saver. You said you were loading on a 550 correct? Grinding down your sizing die slightly will help with bulges in once fired brass. Hope this helps. TXAG Link to comment Share on other sites More sharing options...
shred Posted July 18, 2004 Share Posted July 18, 2004 Well, what I am doing is buying once fired and then dumping it after I fire it once. ... whereupon somebody may well pick it up and sell it again as "once-fired"... hence the need for case-bulge-repair tools. IME "once fired" usually isn't. Link to comment Share on other sites More sharing options...
Kingman Posted July 18, 2004 Share Posted July 18, 2004 Well at least my practice brass no one can touch but me or two other people. My range is private and only 3 people have keys to it. Anyone know the deal on an sdb if you can grind anything down. at matches it is different. Link to comment Share on other sites More sharing options...
Chriss Grube Posted July 18, 2004 Share Posted July 18, 2004 Try the FCD before you go grinding. Most people get into trouble when they start doing home gunsmithing and mods. Link to comment Share on other sites More sharing options...
Kingman Posted July 18, 2004 Share Posted July 18, 2004 The SDB does not have a standard sizing or crimping die. I think It can be changed, but not by merely threading a new one in. Link to comment Share on other sites More sharing options...
