lroy Posted November 3, 2020 Share Posted November 3, 2020 I'm getting about 5/100 not passing by hundo gauge. The ones that fail typically get stuck at the end of the case (primer side) and a line running around the diameter is visible. I'm guessing this is where the size die stops and is caused by bulged brass? Would switching my dillon die to a lee undersized die fix this issue?

Ben53 Posted November 3, 2020 Share Posted November 3, 2020 That's pretty low on the case for bulged brass, but it is possible. I suggest "bulge busting" the cases as needed. I'm told you can do this with loaded rounds but I've never tried it. I'd suggest getting one of the bulge-busting dies and use it in a single station press if you're only going to process the few loaded rounds that won't pass muster in the gauge. I'm sure others will chime in shortly with other ideas as well. Good luck. Link to comment Share on other sites More sharing options...
Jmo2011 Posted November 3, 2020 Share Posted November 3, 2020 Another alternative to bulge busting is to case pro the brass before loading. This made my failure rate nearly nonexistent. Link to comment Share on other sites More sharing options...

Are you sure your dies are adjusted correctly and you are not short stroking the handle? I'm asking because I load a lot of 40(even the Glock fired cases) and never had this issue.

Furrly Posted November 3, 2020 Share Posted November 3, 2020 Lee U-die will fix it!! Link to comment Share on other sites More sharing options...
Kilrb Posted November 4, 2020 Share Posted November 4, 2020 I switched to a Lee U die as well. Fixed the bulge, I looked at Roll Sizer and Case Pro but can't justify the cost. Link to comment Share on other sites More sharing options...
Sigarmsp226 Posted November 4, 2020 Share Posted November 4, 2020 I also started using a Lee U die and I cannot tell you when I have had a case fail (since switching)....Very cost effective way to manage this issue... Link to comment Share on other sites More sharing options...
lroy Posted November 4, 2020 Author Share Posted November 4, 2020 Oof yeah. A case pro is almost as much as a new 1050. I'm gonna give the $20 option a shot first. Appreciate the advice. Link to comment Share on other sites More sharing options...
Southpaw Posted November 4, 2020 Share Posted November 4, 2020 With Lee U die 1% or less fail hundo gauge. Link to comment Share on other sites More sharing options...
CHA-LEE Posted November 8, 2020 Share Posted November 8, 2020 If I was you, I would be more worried about the excessive crimp you are using. That much crimp is deforming the bullet and will cause accuracy issues. You also need the leading edge of the case exposed so it can register the round at the front of the chamber properly.

bigedp51 Posted November 9, 2020 Share Posted November 9, 2020 It also looks like the die is "pushing brass" near the base where your red arrow is. Some guesses on the pushing brass, and the ring on the base. 1. Case off center with the die, meaning the case not centered in the shell holder. 2. Check for a bulge if you are using range pickup brass. 3. The brass is too clean and being grabbed by the carbide ring. Try some Hornady one shot on the cases and inside the die. 4. A undersize die will push even more brass because of it smaller diameter. Link to comment Share on other sites More sharing options...
Tnbb33 Posted November 9, 2020 Share Posted November 9, 2020 Here’s a quick check to see if it’s the sizing die. Size 100 cases, without actually loading, just sized. Then see how many fit in the hundo gage. Link to comment Share on other sites More sharing options...

I pulled the bullets and you're completely right, the bullets were misshapen. I adjusted the crimp to be minimal and still able to pass the hundo then pulled it. The difference is significant. Appreciate your advice. Hopefully these look better. Edited November 9, 2020 by lroy Link to comment Share on other sites More sharing options...

CocoBolo Posted November 11, 2020 Share Posted November 11, 2020 (edited) Get the Redding GRX, I use to run them all thru it but after a while I just put the rejects thru it. Yeah Yeah putting a loaded round thru it might be dangerous but I don't have any holes in the roof, don't stand over it. I have a case pro, and I roll loaded rounds thru it as well, when they fail the plunker. Primers are too scarce for rejects.

lroy Posted November 18, 2020 Author Share Posted November 18, 2020 Just to update, since switching to the Lee Undersized die, my fail rate has gone from 8% to basically 0%. 20 bucks has made a huuuuuge difference. Link to comment Share on other sites More sharing options...
limitedgun Posted November 21, 2020 Share Posted November 21, 2020 I used to use the GR-x Redding and it did fine. I have since switched to Rollsizer.com equipment and my time saved is huge. Even with the Bulge Buster dies I used to have some failures, and I try to minimize or eliminate all failures. Lots of great ways to minimise and eliminate, just have to find the best way for you. The most important part is correct die adjustment. Link to comment Share on other sites More sharing options...
zzt Posted December 6, 2020 Share Posted December 6, 2020 I solved the problem by using a Lee FCD to crimp. It sizes on the way down, crimps and sizes again on the way up. 0% failure rate due to bulge. Link to comment Share on other sites More sharing options...
Yeti Posted December 6, 2020 Share Posted December 6, 2020 Nice looking load now in the follow up pic. The GR-X is nice, but it is an extra process. Rollsizer looks sweet, but I really haven't needed one. Some rip on the LEE FCD, but this is a handy tool to have. Unless you are using way oversized bullets and thick brass you should generally not have an issue. I have on occasion used a U-Die for jacketed, but not for coated, lubed or even plated bullets. The FCD is helpful and easy to incorporate. Link to comment Share on other sites More sharing options...
Unicorn187 Posted December 25, 2020 Share Posted December 25, 2020 Probably not popular but... i use a single stage press with a lee factory crimp die (all the guts out of it) and i push through the “bulged” round. Works 100% of the time. Link to comment Share on other sites More sharing options...
