I know a lot of guys use Bevel base commercial bullets. Some years back I did. And could not find a suitable load for them. With out leading. I now cast all my own bullets. As most know different Alloys need to be pushed at different speeds. To have proper Bullet Obturation. Now for my question, Being a commercially cast Bullet .they are some what hard. Logic would dictate a harder bullet should be pushed harder. How ever. Being Bevel Based Bullet. Do not obturate to seal the bore .As well as plain Base. The result is gas cutting around the bullets base with hotter loads. My guess would be these Bullets should only be loaded in mid range cast bullet loads only. Am I missing the point some where.
