This morning I tried a water jug penetration test with one of my two favorite hog back up loads; a cast lead WW Lee 515-500 with the base faced down to 400 grains and sized to .505 then lubed with shortening, one .024 card over 100 grns(V) T7 2f, and a Winchester 209 primer. When I had a chrono this load averaged 1270 fps. I'd never done a penetration test with it before.
I took a guess and lined up 4 one-gallon water jugs, followed by 5 half-gallon cranberry juice bottles all placed a couple of yards from the muzzle. An 8 foot high earth berm was the back stop. All 4 gallon jugs exploded, the first four juice bottles were drilled thru center with the screw on caps missing. The 5th juice bottle had a hole in the front with my bullet lying in the center at the bottom.
The length of the bullet nose from bottom of first driving band to the flat point had been shortened from .500" to .465". The point had widened from .285" to .377" and the flat tip now had a shallow dish shape. All measurements are approximate according to my poor close up vision and plastic/digital Mitutoyo calipers.
Total penetration was 36" of water in containers, and I had a little fun.
