G'Day JFE and Daryl,

Thank you both for that info, including that attached article, JFE!
I think that was probably the one I read before and had forgotten about.

Looking forward to loading up a few rounds (I need to set up the Dillon 550B first) and putting a few rounds, into the bullet trap. I do this initially, just to work up a Maximum Safe Working Load (MSWL), then head for the range or paddock, to shoot some groups.
I want to get some Hornady 0.451" 300grn XTP Magnum bullets and use them for huntin pork, etc.
I also want to machine up a Scout Type base and fit it into the rear sight dove tail and mount a Trijicon RMR, Leupold small red dot electronic sight.

Thanks again
Doh!
