G'Day Fella's,

I had a bit of a clean up in my workshop/store area and came across a couple of Dewey .40 cal/10mm handgun bore brushes (refugees form when we (Australians) were still trusted with handguns larger that .38 Cal). Any way I measured these up at 0.431" diameter.
That should be fine for loosening the carbon and other stuff in any .404 Jeffery?

I hope this may be of some assistance, to you other .404 users!
