I don't shoot magnum loads anymore, but have shot many of the #358429 and #358439, the ones that are allegedly too long for the cylinders of 28s and 27s. These were designed as .38 Special bullets, certainly, and can be crimped in the crimp groove with a .38 Special loading. However, to use them in the .357 Magnum cartridge is really no hindrance. The bullet is simply seated a little deeper and crimped over the bullet's shoulder to give an acceptable OAL for the short cylinders. Accuracy is unaffected unless the crimp is overdone.

A better .357 Magnum bullet for those who must use a crimp groove for crimping is the original .357 Magnum bullet, the Hensley & Gibbs #51 SWC design, about 160 grains. There are others that will also work.
