I purchased a used RCBS 44-200-FN off the forum here a while back. I finally got it cleaned up and tested. It casts .428 bullets. I was hoping for more like .430+.
So my question, did RCBS offer this one in more than one diameter? It’s listed in my RCBS manual in 44 special data.
Second question. Is that too much to of a difference to lap? I’d really like to get .431
I’ve lapped a few, but not that much. Mostly just to clean them up or fix a sticky cavity.
Should I sell it or keep it?
