Sizing twice?

[Pelon]

A friend recommends a second sizing with a fourth die after crimping. Does that sound reasonable?

Stand easy, men!

Next week I will unveil my new 23x sizing system, complete with 32x seat and crimp stations!!!

Lee makes a sizing/crimp die that full length sizes at the same time as crimping. I guess his idea is just an offshoot of this usign 2 dies.

I use the Lee factory crimp die not because it sizes (which it does) but because you can crimp a bullet that has the cannelure in the wrong place or none at all. It also gives a nice looking crimp that seems to improve my reloads bullet pull, give more consistant velocities.

On the down side it seems to work the brass harder.

Steve:

Will it fit on my bench, it is only about 6 ft wide.

Pelon,

Why bother?

 

[Pelon]

Why bother?

I´ve heard it makes feeding more reliable.

I do not crimp at all and have not had feed problems. I reload 9mm in FMJ and .357 in SWC and JHP and tend to stay on the minimum side more than on the maximum powder charge side. If you tend to go to the high side I'd be more concerned about crimping and the impact recoil may have on the unfired cases.

The Lee is the best thing since sliced bread......once you've got one you can just about throw away your cases checker guages.....since i got one in 45, every time i drop a loaded round into a case guage. it drops all the way in with no resistance whatsoever.....even those AMERC 45 cases with are so thick that a lead bullet will swell them up so fat that they will not chamber.......another thing is that the amount of crimp is adjusted by a knob on the top,,,,not by lowereing the die body like everybody elses die....Dick

dodgestdshift: A double-wide extension to your single-wide mobile home will be required for the sizing system, but I assure you, no one else's ammo will be sized more than yours!

A lot of IPSC guys size after the bullet has been seated and crimped to iron out any bulges in the case created during the seating process. Some of them even use a push through die, to get the bits that a normal sizing die doesn't get.

Is it useful? I have no idea.

owen

 

[Bottom Gun]

If your sizing die is doing what it should, your cases will feed reliably. I've reloaded for 30 yr and have never had a sized case not feed or chamber properly unless the rim of the case was deformed but this will normally show up during your sizing process.
If you use a Dillon press, you will have to set another press up for your second sizing operation since all four stations of the Dillon are already occupied by other dies.
I would also be a little concerned that your second sizing operation might loosen your crimp a bit but, having never tried it, I wouldn't know.
I really don't see the need for a second sizing.

Yes, you should roll crimp handgun cartridges, especially magnum revolver cartridges. Bullets will tend to walk forward in your cases from the recoil of a heavy load in a revolver and they can prevent the cylinder from rotating.
A taper crimp should be used in a semi auto handgun.

Steve: I'll only buy it if it's very expensive. If it's shiny, I'll take two. (Wait'll the chicks find out!)

p.s. I'll pay no more than twice the asking price.

 

[Steve Smith]

I will chrome plate both of yours, and write "BLING!" on each one, so you can have BLING! BLING! sizer machines!

I can barely beat the chicks off with a stick here at the factory...you'll love it!
