keyholes

[moesett]

in a 4 inch 625 I load 4.0 grains of clays, 230 grain moly round nose, fedral primers. I have been getting some real ugly keyholes in the cardbord, some holes are normal some raged keyholes. anybody know whats going on here?

Odd. That's the top end for 230g with clays.

I'd mic the bullets to get true diameter, maybe they are a little skinny?

How are the throats? Didn't some 625's have problems with throat size, or were those 25's?

I'd look for one throat sized a little too small.

4.0 is max with straight Clays for a jacketed round, not sure about cast.

If you taper crimp too much it will tumble. Don't ask me how I know!! :shock:
