Like almost everyone else I always considered a brush gun to be slow and heavy, like a 30/30 or a slug gun.
I personally have never liked the 30/30 for deer hunting. (I know its probably killed more deer than any other gun) But I’ve seen some poor results from a couple that were used in my group.
This fall while hunting the very thick edge of a swamp, I shot a deer that was moving thru and acted like he was going to bolt before he made a clearing.
As I had the crosshairs on him I told myself there is a good chance of hitting a branch, but the shot couldn’t wait if I wanted that deer. Well the deer dropped in his tracks and never moved, when I went to check him out I noticed the there was a much larger entrance wound than normal, but still a full pass thru.
Looking back towards my stand I found I also put a killing shot on a small tree, now thats what I call brush gun performance. My gun, a 7mm Rem mag with a 150 grain Fusion bullet, not exactly slow and heavy.
Behind and to the right of the first picture you can see where he dropped.
