Has anyone used these adaptors. I am looking at using the 50 grain adaptors with Grizzly 120 grain broadhead. They advertise the 50 grain ones as a 21/64 diameter, will these fit the 11/32 ferrule of the grizzlys?

James,I haven't used the titaniums but 21/64"=.328".My 200 Grizzlies measure .333" inside.Many 11/32" steel adapters I buy don't seat fully in the Grizzly ferrule.I bet they would work real well.It would be worth giving them a call.
