40 S&W Bulge

[M-61]

Has anyone tried the LEE 'Bulge Buster' when reloading 40 SW? I could use some help with this one.

Redding makes one and they both work to smooth that area over to fit the gun like almost a new cartridge.I would go for it.

I use the Redding with good results. Sorry I don't have any experience with the Lee.

I was having a problem with "glock bulge" on my range pick up brass in .40 S&W I load with a dillion 650. I removed a small amount of material on the bottom of the carbide size die (rcbs) below the carbide ring to allow the case to go further up into the die. I then adjusted the die all the way down until there was a fair amount of resistance when the press was operated (over cam?) this cured all the problems I was having with glock bulge range pick up brass without an extra sizing step.

I check all rounds shot in competition by removing my barrel and dropping them in the chamber. They need to drop in and when inverted fall out. I haven't had any that wouldn't chamber since the die modification.

How much material did you remove?

I use the LBB on all my 40sw cases, the Redding GRX is te samething but 2-3 times the price, my suggestion is to throw away the crimping portion of the FCD, reason why is the carbide sizing ring resizes the bullet which leads to inaccurate rounds.

Get a Lee Factory Carbide Sizing die, it's made to do a final sizing on a loaded cartridge, and depending on how it's adjusted can put a straight crimp on the brass if desired. It eliminates the "Coke bottle" effect and insures that the loaded rounds gauge properly and feed properly.

I was turned on to it by competitve pistol shooter who loaded around 40K of pistol a year. They are the last dies on my Dillon 650 tool heads for pistol ammo. They are inexpensive and they work.

That is what is needed...a LEE CARBIDE SIZING DIE? or is it a LEE FACTORY CRIMP DIE?
Thanks

I removed all the material from the bottom of the carbide sizer right up to within .002 where the carbide ring started. Then made sure that the shell plate contacted the bottom of the die firmly, I shoot rifles but pistol shooting is my passion. For a few years I shot 20-30,000 round per year practicing for the bianchi cup. This trick was suggested by a friend that shoots nothing but USPSA and it seems to work as I was having about 1 per 50 failure to chamber malfunctions with glock range pick up brass before the die modification and none since.

Make sure that you are not creating the bulge by over crimping......this is a whole different issue and would not be cured by modifying your size die. This happens easily when you are seating and crimping at the same time-die. If your brass varies in length sometimes the crimp will get so tight while the seater is still seating the bullet that you can bulge the case when you seat the bullet. Most would recommend seating the bullet then adding a taper crimp to a .40S&W at the next station with a seperate die in a progressive press. This will greatly reduce the chance that you are causing the bulge yourself when seating the bullet with cases that vary in length.

The bulge is occurring during re sizing. Clean brass, correct shell holder,not any excessive force at all.....I wind up with a bulge that at first glance you would think it is a BELTED case!
