I found a new mold for my .308x1.625 Ardito. It is the Accurate Molds 31-155W. Throws a 155 grain bullet with 3linotype to 1 ww. 159grn with gc and lube. The bullet base is .312 and has a tapered area ahead of the grease groove that matches the taper in my Ardito throat. I managed a .549" group today with 20 grains of R-7 and a 14" twist barrel. I haven't tried it in a "normal" .308 rifle.

Thought you fellow Ardito rifle owners might want to know.
