roll or taper crimp for 38/357

I'm missing something here. What's the drawback with taper crimped rounds when using a speedloader?

If you are a competitive shooter you are probably shooting an 8 shot revolver (but same applies to a 6 shot). Trying to do a quick reload with taper crimp rounds is very slow because the edges of the rounds catch the cylinder and you have to wiggle the moon clip or speed loader to get the rounds in. Unless you do major throating to the ejector and cylinder the rounds usually will not just drop into the cylinder like roll crimped rounds will.
 
Taper crimp is ideal for 38 wadcutters or bullets without a cannelure. Everything else should be roll crimped.

Even BBwc or HBwc bullet cases, can be crimped

since the crimp does not dig into the bullet, to cause any accuracy problems

as seen in this Remington factory loading and two reloads, of mine.

Good shooting.

 
I wouldn't use a taper crimp on any revolver load. You can apply a roll crimp to coated bullet without breaking through the coating. Just don't be an animal lol.

Once a year I mine my personal sand trap to collect boolits for recycling. My roll crimped coated or plated non-cannelure bullets show no signs of breakage.
 
I think the biggest advantage of a separate crimping die is that you don't have to readjust the bullet seating stem when fiddling with the crimp. The crimping die is really nice with presses that have 5 stations.

I agree that it's nice to be able to adjust the seating depth and crimp completely separately. However, I think the biggest advantage of crimping in a separate step is that the bullet isn't moving downward while the crimp is being applied. This is even more important if your bullet doesn't have a cannelure or crimping groove.

P.S. one of the reasons I like Redding's Profile Crimp dies so much is that it gets the job done with less sensitivity to case length. If a case is a touch short, at least it still gets a bit of taper crimp. If long, just a heavier roll crimp.

Thankful for this post and replies. It has been a number of years since I reloaded for my revolvers and my pistols. Local public range has now opened. Come next year, going to be put out to pasture, so hope to do some reloading/shooting before I move. This will be helpful. Sincerely. bruce.
