Personally I believe a heavier slower bullet is better for brush. I do not want to hit brush with any bullet, but I would prefer to hit it with a 405 grain 45-70 slug instead of a 22-250 going 3800fps. That is just my opinion.

My main go to rifle for woods shooting is a 30-06 with the 200 grain Sierra bullet. It is a carbine length Remington pump rifle. This bullet is doing about 2400-2500 fps from the 30-06. And it is a deadly combination. It is fast enough to be pin point accurate in the wods. And pin point accuracy is important in heavy cover. And the bullet is very flat out to 100 yards. The 200 grain can bore through small brush. But not recommended. Tom.
