Bent FossdalThe .460 G&A was made by Tom Siatos in the 1970's on the .404 Jeffery case. It was made in the full-length and 2,5" version. In your Husquarna, the shorter one would be easiest to do. It will give about 200 fps more than the WinMag.
Dies can be had from everywere, probably easiest in Finland to have them ordered from RCBS. Barrel-length is optional, but I would not go below 22".

jeffeossothe GA short, made from 404 cases . .. I do not believe you will be able to make them from rum cases, which will be rebated on the rim and too thick at the case head... perhaps you can draw them (smaller=draw, larger=swage) down, but USE A ULTRA CASE HOLDER, not a 404, to do this with well lubricated cases.
the 458 AR (see ammoguide for load data) can do 500gr at 2400 with a 24" barrel
