Crimp Police 911!

[The Glockodile]

Just got one of those fancy Redding Micrometer Crimp Dies to try out for my Magnum cartridges.

Might have seated the bullet a little lower, but that’s for next time.

Think the crimp’s all right?

On the side, this also serves as an exploration of hubris and individual delusions of exceptionalism…

If those are high end loads, it's a little light.

If you're going to crimp, crimp!

Throttle ‘em hard?

You won’t take the Crimping Professional title from @Walkalong but it’s good enough for government work.

??????????????????????????

Bullet lower, tighter crimp!

 

[SingleActionAndrew]

A few thousandths deeper to allow a thousandth or two of more roll would be ideal but I don't typically use bullets with that big of or a cannelure or crimp groove and have to compromise with something like that and if I do my job they shoot X ring at 50 yards

 

[kcofohio]

I agree there needs more depth and roll. And to add, the crimp means nothing without good neck tension.

 

[Walkalong]

Agreed

Yes, and with the bullet a hair lower next time it will roll further into the cannelure.

Exactly, a deep bullet puts more material from the case deeper in the crimp grove....

When I used my first jacketed bullets (pre web), I seated the bullets so the case mouth was about even with the top of the cannelure. I then rolled the case into the cannalure just enough to touch the cannalure, plus mebbe .002". Good neck tension plus this crimp worked on all my revolvers including heavy 44 Magnum handloads...

 

[Walkalong]

Something like this.

Measure OAL on 6 of them, load the cylinder, shoot 5 and measure the last one again. If it's not longer, you are good to go.

For your progressive press and safety question, I run powder check dies, if I can. To ensure the measure drops the correct charge and ensure I don't otherwise cause a mistake to occur.

Set up correctly, they can even detect small internal volume changes in the brass, that might also cause an issue.

From starting loads to max, its safer. I don't know of anyone, that uses them, to have had squibs or doubles. Kind of makes them seem cheap...

Before you start rolling the crimp in hard be sure to trim all the brass to the same length. If you don't, some could be barely crimped and others could create bulges in the brass.

Well said, Dogleg....and trim only as much as it takes to even 'em all up...this advice is for straight wall, revolvers cartridges only as they headspace off the case rim.

Auto cartridges headspace off the case mouth so trimming will change the case length allowing it to seat deeper in the barrel's chamber and may result in misfires if excessive. Best regards, Rod

Crimp then pull bullet. Crimped properly will show hard in the knurls. Easier to back off than ease into it. For my abundant ammo stash
