Recently I was re-arranging the stack of old truck tires that makes up my target backstop at the 50 yard distance on my “home range”. On the ground in the middle off the outside stack I found two .480 Ruger bullets that had been fired from my Super Redhawk with a 7.5″ barrel, at a velocity of around 1000 fps. These bullets would then have traveled the 50 yards to the target, went through the thin wood siding to which the target was stapled, and penetrated one side of the tire they hit. This penetration would have been through the tread portion of the tire. The bullets evidently failed to penetrate the other side of the tread.
As originally loaded, the bullets were Cast Performance flat nosed designs of 375 gr. After recovery, they showed rifling marks, and one had some black rubber embedded in a crack that had formed in one side. Recovery weight was 356 gr and 359 gr. I have fired other rounds into this stack, from 300 gr .44 mags to 376 gr coated “Thumper” bullets in .480 from Missouri Bullet Company, but have not done a thorough search to see if any of those penetrated both sides of a tire.
In my opinion, these bullets showed good penetration for the velocity they were fired at – certainly sufficient for hog hunting – and as the photos show, either could be loaded and fired again – with or without re-sizing and re-lubing!
