My .458 B&M barrel twist is 1:10" and has a short 19.75" length !
The throat might be extended to full SAAMI .458 WM.
Thus the .458 B&M+ might be born: Long COL for it is 3.340" or maybe 3.395".
Might equal the longer-barreled .458 WM+ and do it with a short barrel.
When I pick up Old Fugly, I will show the .458 B&M M70 and the .338 WinMag M70 to GUNSMITH.
See if he can do it ...
Will just have to add a "+" stamp to the barrel engraving: .458 B&M+
That is short for ".458 B&M + Winchester Magnum Throat."
