RE: Shooting through brush...
If the brush is touching the deer I probably would, but I’ve never actually been faced with that option. . Otherwise no. I’ve put arrows thru some small openings, but as far as just trying to shoot thru a “mesh” of small limbs, no way. An arrow can deflect far off in short time.
There was nothing I wanted more on this planet than to kill an elk this fall, but I wasn’t going to force an arrow thru the brush in the hopes of doing so. Taking mere moments longer in search of an opening (which likely would have been found) cost me twice, but such is hunting.
