Been shooting Muzzy for decades.The 100 4 blade is my favorite now. I've stuck 5 deer over the years that appeared to not know they were just punctured. Some would jump and look around, some would bound a few times and stop, and one only shook and stood there. One doe started picking up acorns again after the shot. Another walked a few yards and then bent her neck to lick the blood pouring out of her from the exit wound.I only had one buck that ran out of sight after the shot. The rest I watched fall within 50 yrds. because they did not run off before they expired. I've never not had a pass through w the Muzzies. I know mechanicals are all the rage now, but I will never use them.
