12ga slugs are about the same as a 308 150gr.
These are sabot slugs.
Dumb slugs start in 12ga start out with about 2800 ft lbs of energy at the muzzle but lose it fast, down to 2000 at 25 yards and 1452 at 50 yards.
The 20ga starts at 1860 ft lbs at the muzzle, 1330 at 25 yards, 982 at 50 yards.
The crazy thing is that the 410 3" slug starts out at 783 at the muzzle, 553 at 25 yards and 393 at 50 yards, these numbers are higher than the 357 Mag (535, 483, 440) out to about 40 yards.
I still wonder why we cannot use pistol cartridge rifles with plugged magazines for deer in SW Ontario, they are mush less dangerous at long range than the high velocity slugs on the market today.
