Guess Which One
Many years ago, I saw an interesting article in a shooting publication. Don't ask, it was some time ago and I do not remember which magazine.
They took a steel plate. They shot at it with three different cartridges. One was a .270 with a soft tip hunting bullet, another was a .30-06 with full metal jacketed bullet, the third was a standard factory .22-250 with a varmint bullet.
Guess which was the only round to completely pierce the metal plate? I'll give you a hint, the .22-250. The range I go to has a silhouette range. Centerfire .22's are not allowed. They put holes through the targets. Other rounds like .270's, 308's, .30-06, and so forth will not.
So, a bullet that can pierce steel can not penetrate a deer?
