About that particular .458, I was told by a close friend, who also knew John VERY well, that John showed the ctg. to R. WTBY who was visiting him (John) in his Kalispell shop.

John demonstrated how a full load in a necked up .378WTBY (.458) at about 2,650fps, would not shoot as deeply in Oak as an identical 500gr. FMJ reduced to 2,200fps to 2,300fps. Roy went home and then introduced 'HIS' new .460 Magnum.

The mutual friend was Lester H. Hawkes, previously of Kalispel, also friend of Les. Bauska.
