Probably sounds like blasphemy to some, but about the only use I have found here in rural Manitoba - for the 458 Win Mag, I lob out 485 grain cast lead bullets, and the 9.3x57 uses 285 grain cast bullets - never checked the speed, but not likely more than about 1,200 fps - like really big 22 Long Rifle, I guess - just a total "old guy" hoot to take them out with the aperture sights and blast away at gophers in a pasture - occasionally hit some, I think - lots of "collateral casualties" from flying dirt though!!! The 14 year old grandson prefers the 4.5-14x40 scope on the CZ 452 Silhouette, but he will eventually catch on!!!
For the black bears in back yard, I have the 9.3x62 with full power 250 grain Accubond - have not had to fire, yet, but now we have a new-to-us Bulldog, that does not seem to have enough smarts to know when "retreat" is actually a smart move. So, might have to take care of business one of these days - lots of bears here; but we only have the one dog...
P.S. - total apologies to OP for completely de-railing your thread....
