I have see it written (by authors I trust) that bevel base cast bullets are not capable of the same level of accuracy as flat base ones.
The reason given is that the flat base bullet will "expand" (there is a better work for it, but I cant for the life of me think of it, somthing with an "o") to fit the bore. And that flat base bullets exit the muzzle more cleanly and with less disruption.
I have tried to test this myself, using soft swaged Flat base and 15BHN bevel base cast bullets under identical loads. I want to say that, yes, the flat base bullets are more accurate, but my test was far from scientific and there are a ton of factors (the load used, the gun used, how I was shooting) that make me not trust my results.
I have made some poor bullet purchases in the past and don't want another box I cant use sitting around my house.
