People this thread is starting to digress, one could argue SD, BC , taylor knock down values etc,etc, ad nauseum, but one variable is always constant- that no scenario is exactly the same, no bullet will hit at exactly the same point on exactly the same animal. As John said he was only answering the question, so lets stick to that.As for me i've only had about 16" of penetration on a 200lb black russian boar, and that was with a 44mag and the 250gr Nosler/partition gold load, bullet was recovered in the off side grisle plate and weighed 231gr and lost one petal.This was out of a Win 94 carbine with 20" barrel and the pig dropped at the 30yd shot.
