by I saw this YouTube video by Ron Spomer that he released just yesterday. He compares shooting water filled milk jugs with a .375 H&H and a .22-250 Ackley Improved. You have to watch the video to see which cartridge wins.
Shooting water filled milk jugs reminds me of my late teens when my friend Robert and I would go to the range and shoot them with everything from a .22 to a .30-06. The overfilled ones were the best as they reacted more violently when hit by the .30-06 bullet. Call it plinking or call it a penetration test, it just fun.
