Maybe the taper-crimp die is for use with Single-Shot rifles & pistols like the Thompson Center Encore??

Or if it has a bullet seater function, you can seat with it and not crimp, and then crimp with the roll-crimp die.

They got the sale & extra money out of you for it though, didn't they!

I recently got the same set. The extra crimp die is labeled "TC" which I thought meant taper crimp, but it will definitely form a roll crimp if adjusted correctly. If I remember tonight or tomorrow, I'll post some pics of crimps I've done with it.

the taper crimp doesnt have a seater in it so if I want to roll crimp still have to use seater with roll crimp. I tried the one thats marked tc and it looks like a standard taper to me? and yes they got the extra money out of me.

Call Hornady and find out what they were thinking you could use it for?

Have you tried taper crimping into the cannelure? It's fun.

Taper crimping into the cannelure. That's a good one. Reminds me of the old adage to never put anything in your ear except your elbow, but not nearly as helpful. The OP is a brand new reloader. Why yank him around?

Calling Hornady and discussing with them is the correct course of action.

I'm not yanking him around. Taper crimping into a cannelure is just as effective as roll crimping into a cannelure.

I use a taper crimp for plated bullets, I check the COL of the last round in the cylinder for bullet jump. This gives me an idea of the load limits for plated bullets with the taper crimp.

I have cut the plating using a roll crimp so I like the taper crimp die option.

Just because you have a 454 casull doesn't mean you can't load it like a 45 LC.

When one begins to turn the case mouth into the cannelure, the crimp ceases to be a taper crimp and becomes a roll crimp.

A taper crimp die can be handy if you want to use cast or jacketed bullets that don't have a cannelure or definite crimp groove, particularly with relatively light loads using these bullets. You can do this with a roll crimp die (set for "no crimp") but it just doesn't work as well. Otherwise, the roll crimp is the ticket with heavy loads using bullets that do have a cannelure or definite crimp groove. The extra die is kind of nice considering the $70-$90 cost of the set. I'd still discuss the process with the folks at Hornady and let them guide you.

I'm not yanking him around. Taper crimping into a cannelure is just as effective as roll crimping into a cannelure.I agree. A heavy taper crimp works just fine with a jacketed bullet. You have to experiment a little as to how much.

If you are loading for lever-action rifles -or- should I say tube-magazine type of firearm you MUST be able to roll crimp your finished cartridge.
Taper crimp most everything else can equate to less unneccessary working of the brass.
