What Type of Crimp

[Walkalong]

Does that Factory Crimp put more stress on neck mouth? From the pictures I looked at it looks like a serious crimp.

It can be adjusted from light to heavy. I prefer a taper crimp over it, but then a consistent case length will be more critical. I trim em every time for .223, despite the fact that you can get away with doing it every second or third firing. I don't keep track any more, so I just trim every time. I DO check cases for signs of impending case head separation. If numerous cases in a lot start showing the tell tale signs, I scrap the lot.

Proper neck tension will require 40-50+ pounds of force to move a bullet in a case.

That amount of impact from a poor feeding rifle or magazine will bend a bullet nose sideways before it slips.

Agreed, but I still like to crimp my blasting/plinking/SHTF ammo.

That said, and I know you agree with this, NO amount of crimp will make up for poor neck tension...Period.

Thanks for all the input.

Do you use stripper on the mini to load ammo?

No.

Takes longer to put reloads in stripper-clips then it does to just load the magazines with loose ammo in the first place.

To CRIMP OR NOT TO CRIMP?Has this not been discussed before?

As bad as i hate to admit this, crimping with the Lee fcd does help accuracy with my AR. I think i will polish down the expander some more and see what happens. I have plenty in case i ruin it. There, i said it.

You guys have added a lot of insight on this for me. Again I'm just getting back into this again and want to learn and be carefull. I appreciate all the tips and advice. After rereading my Lyman handbook this makes sense.

So if I have this part correct for you guys that don't use a crimp, you just setup your bullet seating die to apply enough pressure to securely hold bullet in the case, correct?

The sizer and expander ball determines neck tension. If the expander is opening up the sized neck too much, you can turn/polish it down to get a bit more neck tension. If the neck part of the sizer is too big, another die is the answer. Of course, with the bushing type neck dies, you control neck tension with the bushing size.
