I recently traded for another Ruger .375Alaskan and it came with a good quantity of custom loaded ammo- both .300gr TSX and some rather unusual looking 370gr hardcast lead rounds.
Just out of curiousity- how fast would a round that heavy be leaving the muzzle? I don't have access to a chrony right now so I'm looking for educated guesses.
Other than shooting through a battleship hull, what would you do with a long chunk of lead like that? I'm guessing stem to stern penetration would be the order of the day.
