C.O.L in 9mm using HP-38 and berrys 0.356 RN projectiles?

Like a few thousands 1 to 3 ?

Never had any issues really just wondering what others end up with.

I try to stay as close to 0.125 but never fails there are always some that range between 0.123 and some at 0.127.

I guess kinda like powder a little it seems to vary within a grain on the digital scale and very close on a beam scale.

Now crimps I can get 0.376 to 0.377 everytime :)

I get about 5 thousands on a 650 loading 9 with mixed brass. It doesn't bother me for USPSA use.

I use a dillon 650 to so I am close to you.

Mixed brass here to :)
