The common misconception that bevel based bullets were developed for easier automatic casting has been a misnomer for as long as I have been in the business. Bevel base bullets were developed for use for commercial loaders to make loading cartridges easier.

Automatic casting machine molds can be made plain or bevel and makes no difference in the casting process.

Molds that were hand cast molds and then adapted for automatic use gave problems when such designs were not made for such use and had nothing to do with the base design.

The accuracy issue should be laid to rest as bevel based bullets are just as accurate or even more accurate than their plain base counterparts if all the other design parameters are good such as driving band length and nose profile and weight balance to the design.

A properly designed bullet with low weight deviations fitted to the gun will yield the best results for accuracy.
