Setting up dies

[Scott]

Not enough crimp can be bad if it leads to bullet set-back...

What is bullet set-back?

What powder and charge did you use? I am going to guess the same as what we used at my house.

Yep, identical. Figured I'd keep it simple. :mrgreen:

What is bullet set-back?

Thats the bullet being pushed back into the case when it hits the feedramp.

One way to check for it is to cycle the same round through the gun a few times, then measure it to see if it got any shorter than it was before you started.

Loading ammo short will make pressures go up in a hurry. Thats bad.
