Reply To: sizing die
Ok. Most of the .25 barrels I have messed with are .243 land .250 groove. I haven’t bought jsb’s for a long while as I have thousands. All went thru my .250″ die and all heads were sized, so all had heads above .250.
Don’t have a good answer as I have a similar issue with my .22 as described above. I still size skirts though.
