Straight wall pistol brass help. Sized but not always sized?

[mehavey]

BTW... if the OP has some loaded cartridges that (now) don't fit into the cylinder,
he can fix that problem by removing the depriming pin from the sizer -- and gently
re-sizing them just enough to resolve the bulge/fit the cylinder again.

Once the resizing die is adjusted for one cartridge, that same setting will resolve the rest.


(+1 on making sure the crimp and crimp groove are aligned once crimping starts)

A couple of years ago I loaded up 50 rounds of 38 Special with Lee cast SWC's. Most would require a slight push into the chamber of my S&W Model 67-no dash. After firing they were hard to extract. I know that on here it is stressed to not over crimp, but there is a balance needed between too slight a crimp and too much. I had resized the brass all the way. So with the 67 close by, I slowly recrimped the rounds until they'd "plunk" into the chambers. And, there was not further extraction problem either. I had not thought to check on how they chambered before loading them. A slightly increased crimp solved the problem. But I have learned that before I load a batch to try the "plunk" test even though it is normally reserved for semi-autos.

I've had that problem with doing roll crimps on brass cases that were longer than the others and what the seat/crimp die was set for.
If you can feel a little bit of bulge on the troublesome case mouths-- that's it.

This thats why I trim all my roll crimped brass any long one will bulge when roll crimped
