From fingers284 in another thread:
I have removed wax lube from commercial hard cast so I could PC them just for comparison purposes from the groups "as bought" to pc'd.
Every hard cast I have tested have went from 2.5 moa with fliers and such to 3.5 or so... to very consistent 1.25 moa. with the same rifle. So far I have had basically the same results with 3 different guns. So far the gratification with the improvement makes the time worthwhile.
What rifles? what calibers? what loads? more info please!!!
Plus, if there is a discussion that starts out this way, somebody please point me.
...and anybody with further comments, please chime in.
Thanks
