Crimping Question

[2Bad4u]

First of all I'm pretty new to reloading and I have a question regarding roll vs. taper crimping.

My understanding is that roll crimps are typically better for revolvers, and bullets with cannelures. Taper crimps are used more with semi-auto pistols, and mainly to remove the bell/flair from the case.

Now here's my problem. This is the first time that I'm reloading wadcutters for my S&W 686. I have some Cam-Pro plated .38 caliber 148gr HBWC (hollow base wadcutters) bullets. The manufacture recommends a heavy roll crimp for this projectile, but my Dillon crimp die only does taper crimps.

Please advise - THANKS !!!

All I ever do is taper crimp with all my handgun ammo revolvers included so you should be fine just be careful you don't over crimp with a taper crimp it's pretty easy to cut through the jacket with a over crimp

I reload 38 wadcutters and all I have ever done is a taper crimp, all you have to do is remove the flare from the mouth of the case after the bullet is seated.

The only handgun ammo I roll crimp is heavy magnum revolver loads, it's supposed to help the powder burn more efficiently and prevent bullets from moving out of the case from recoil.

Thanks guys. I taper crimped 250 rounds today so I'll be off to my gun club tomorrow. It will be my first time out with my revolver.

Does your bullet seating die not do roll crimping? Why wouldn't you just do that?

From the OP's original post:

From the OP's original post:

Yes, I realize his crimp die only does taper crimps, I'm asking about his bullet seater.

The Dillon bullet seating die only seats/sets the bullet to the OAL, the crimping die only taper crimps.
