Hi lone hunter,
my rem brass measures .337 may not be dead accurate only using vernier caliper not micrometer.
Are you using the expander ball, as far as lube i tried graphite,oneshot and ballistol all work with other dies rcbs,lee may have to try the imperial wax.
I will get a .336 and try again i just tried a .335 without expander ball and the case fitted on the pilot for trimmer.
I guess different brands of brass will affect size of bushing as I know my 300 ultra nosler brass is thicker in the neck than the rem brass for my 308win.
