    Roll crimp for revolvers.
    Taper crimp for autos.
    Tapercrimp for revolvers when using hollow base wadcutters or when using bullets without a crimp groove, although they will pull out if the recoil is strong.

    Cool that is what I needed to know thanks, now I need to return my die set, I got a taper crimp set.

    I did not know they made a taper crimp "set" for .38/.357. They do sell separate taper crimp dies for .38/.357, but the sets I have seen were all roll crimp, because that is what is needed 90+% of the time.

    918v has nailed it!

    Yes he did, but I still wonder what "set" the OP has that came with a taper crimp die for .38/.357.

    Prolly a Redding set. Redding makes both roll and taper crimp sets. Sorry for the harassment.

    In earlier posts, Caveman4 indicated he got an RCBS starter kit.
    Assuming he also got RCBS dies, I would bet dollars to donuts he got a roll-crimp die with it.

    All it needs is proper adjustment to roll-crimp.

    If you need help with that, report back and someone will tell you how to set up your seating die to crimp properly.

    rcmodel you are right, but I found out the hard way that rcbs makes both for 38/357, and I will report back, going to reload some 38 this weekend so me and the wife can go plinking.

    Taper crimp is not a problem in 38-.357, it's all I use. Unless you are shooting heavy loads in a scandium frame gun taper crimp will prevent movement in the .38-.357. I load up to 170 gr bullet@1300 fps in the .357 and taper crimp with no bullet movement in recoil. Now the .44 mag or heavy .45 long colt may be a different story.

    Agh. Sounds like RCBS makes both as well as Redding. Learned sumthin'. Of course, I haven't researched .38.357 die sets in many years.
