I see what you mean about the 'bulge' at the base, these two pics show two rounds of factory ammo on the right and two of my reloads on the left (with the black stripes). The reloads are sitting high because of the 'bulge', I'm wondering if the small difference will matter and is there a way to correct it anyway? I'm currently using a Lee Pro1000, will a Dillon produce any different results with regard to resizing?

I've noticed that of all the mixed range brass I have for reloading, Federal and Winchester slip straight in, whereas almost all other brands sit ever so slightly high as shown in these pics. However all the reloads that I've run through the resizing die now sit at the same height when dropped into the barrel.

Still haven't made it to the range yet, maybe Thursday this week.
