The 3-Die Taper Crimp Set is for loading straight-wall cartridges. Its steel Sizer Die sizes the case and de-primes. Note: Cases must be lubricated. The Expander Die expands the case to the proper diameter to accept the bullet, and it imparts case mouth flare/bell for bullet feeding. The Seater Die seats the bullet and taper crimps.
A shell holder is not included with this die set.

I have never had any issues with RCBS products, but FF&F is a top notch seller and I will always but from them first.

I like the look of them. I haven’t been able to try them out do to the fact that I can’t find primers. My only concern is that they need case lube to resize the case. I’ll have to wait until they start to make primers again to try the dies out.
