thats a tough call.definately wait.but i dont know if 4 inches is enough to kill the deer through the shoulder blade.at 23 yds you only got 4 ins deep.what poundage do you shoot?i shot 1 deer in the shoulder and it went through one side and the broadhead was just sticking out the other side and it only went 40 yds.it was a 30 yd shot.good luck and keep us posted
