send off a note to Geoff McDonald at Woodleigh Bullets & see what he can do.
Not wrong about the calibre & your need to swage down - maybe you need to "bump up" the .412" that he has for your rifle? Graeme Wright has a section in his book detailing what he did to make things fit - need a good fitter & turner...& a very big hammer!
Great job the .405 did & the 38-55 as well.
