Thanks VM
To follow up, Sunday morning I did some penetration tests in water jugs with a .223 and 50gr V-Max's. I hunt pastures on the valley floor here in the Bitterroot and am never out of sight of a neighbor's house. Frangible bullets are VERY important to me.
The load is 24gr of IMR 4895 and the 50 Hornady. It shoots tiny groups at about 3050 in my rifle. I used a standard plastic 1 gallon milkjug and a 1 gallon orange juice jug that's about 5" thick, placing a piece of plywood scrap behind both, shot one jug at a time. At 50 yards, the bullet made only a wide, shallow dimple in the back wall of the orange juice jug. NO exit. Same with the milkjug, but didn't even reach the back wall. The bullet fragments I recovered were no bigger or heavier than your average fingernail clipping.
I was out of OJ jugs for the 100 yard testing but I doubt it would have mattered - the bullet didn't exit the milkjug at 100 either.
Conclusion - the 50 V-Max is a very frangible bullet, appropriate for "developed" areas. Unfortunately, this raises another question - is it TOO light for coyotes? Oh well....
