As it is a custom job they wanted a dummy round.

... and?

Send one. I delivered to Rule303 his Lee 416Rigby factory crimp die a few weeks back, plus picked up a number of other stuff from Lee. Surprise was they sent the dummies all back too.

Lee is very good to deal with and sending dummies is no problem. Only 'issue' I had is that the prices quoted seemed to be 'maximum estimates' as freight and the export fee was less than they originally quoted.
Cheers...
