Gonic Shooters Help

[Nit Wit]

Anyone shoot a .50 cal GA-87? I have some original Gonic .500 bullets, My calipers say they are .492-.493; These go down the bore good. I cast .500's sized to .498 had to beat them down. Bent my steel range rod. The original package says th G bullets are .500, not so. This is driving me crazy!
Thanks

Gonics have smaller bores size down some more.Get a Lee sizer and open it up

Bullets must be less than .500" of pure lead
I shoot a GA-93 50 cal.
Great rifles!
