Even more info on the 163 grain AP...
You guys will love this..
4 years ago my brother and I did some low budget penatration tests in the hinterlands of South Dakota, where he lives. We had some Talon 150 grain 30-06, Talon 163 grain AP 30-06, some Canadian Green tip (M855) steel core 223 and some Winchester usa 30 m1 carbine 100 gr FMJ.
At 150 yards ( yes we are big chickens ), from behind a old brick wall, we shot at 2 3/8 inch steel plates, one behind the other (It was an old 1920's rockpicker).
The 163 grain black tip AP out of my 43 springfield garand waltzed right through the first plate and buried the penatrator half way through the second plate.
The 150 grain ball out of my garand blew a hole on the first plate big enough to stick a pencil through.
The Canadian green tip out of my 20" bushmaster made a 1/4 inch deep crater in the first plate, couldn't find the steel core.
The 30 carbine made a brown smudge on the first plate.
there is no doubt in my mind that the 163 grain stuff would disable a car out to a quarter mile, maybe more.
