About every ten years or so, some gun writer gets into the "brush gun" question.
I've never seen it differ: The amount of deflection varies with the distance the target is behind the brush. That is, if a target is more than ten or fifteen feet in back of a clump of brush, the odds are greatly against hitting it.
Omitting the explosive combos like the centerfire .22s, e.g., it doesn't matter if it's a pointed bullet, a round-nose or a flat-nose. It doesn't matter if it's a 6mm or a .45-70.
And, of course, a bullet can travel through some brushy stuff and not hit much of anything at all...
An oddball personal experience happened to me when I shot at a deer's heart through what I thought was one prickly-pear leaf. In reality, I shot through FIVE leaves! A piece of the bullet curved off-path to the deer's ear, and he fell. I dunno; maybeso ten yards worth of spaced-out pear leaves...
In other words, I'll take luck over skill, anyday.
