Favourite magnum???
Currently fixated on the 338/378 in custom, long barrelled Ruger #1., But,
I have all the weatherby magnums, as well as the standby 7mmRem, 300 win,
358 Norma, 458 win,458 Lott, 375 H&H, 470NE,
Also have the King of MAGNUMS...585 Nyati (750gr @ 2500fps)
Having said all that I prefer the .338 cal, be it in 338 win, 338 RUM, 340WBY,
or 338/378 and throw in the 338 lapua....excellent cal, bullets and performance!!
my 2 cents
