My 30-06 will shoot thru 6-7 milk jugs with 150g Hornaday interlock.
7mm mag = 7-8 milk jugs 139g interlock
.58 cap lock = 13 milk jugs 440g R.E.A.L. bullet
.62 cap lock = 18 milk jugs or through a plastic 55 gallon drum long ways. 900g custom made bullet.
I also filled a plastic 55 gallon drum with wet newspapers. The .62 averaged 29 inches of penetration and an inch and a half mushroom. 3 shots tested with 90/10 pure led to wheel weights.
The number one cause of death in the 20th century. 290,000,000 citizens were first disarmed and then murdered by their own governments. This number does not include those killed in war.
We're from the government, we're here to help
