I like the video, but I have to disagree with you on something. The purpose of a taper crimp is not to aid in holding the bullet in place. Its purpose is to simply remove the remaining flare from the belling step. If a bullet is setting back during cycling, then there is not enough tension between the bullet and case. The bullet is undersized or the case isn't being sized down enough. If so, that problem should be fixed.

@bretak74 It's used for both.

so 45acp would need a taper crimp correct? .223 would ned a factor crimp(lee)? what about .30 carbine?

[ammosmith]

@xBiGTxLPZx A 45 ACP and a 30 Carbine would need a taper crimp and a bottlenecked case would use a roll crimp and so would a rimmed pistol case like the 357 or 44 magnums. The factory crimp die reproduces the factory crimp and they also are available in a taper crimp form from Lee. I have one for the 45 ACP. Very nice and it's also carbide now...it's a newer offering.

" This period of instruction" "for instructional purpose only" ..... just wondering have you ever served in the armed forces?

[ammosmith]

@Blazingspitfire Yes...Marines.

what's the difference between the taper crimp and a very light crimp from the FCD?

don't they both slightly squeeze the mouth of the case?

[Blazingspitfire]

@ammosmith figures.

[ammosmith]

If it has no cannelure don't worry about a crimp. If it does a have one then use just enough to crimp the case mouth into the groove and no more.
