Just alittle FYI thread. I have been shooting rage 2-blade since I got back into bow hunting in 07'. That year I shot 3 deer with them none going more than 70 yards and all bleeding like crazy. First two were does broadside 15yds., one complete pass thru & one just broadhead pass thru. Next was a 145lb.(field dressed) 8pt buck quartering away hard at 8yds. Arrow went in 2" behind last rib came out off shoulder, broadhead pass thru not complete. In 08 I shot 3 deer all fell inside of 60yds. and bled very well. First deer was a doe at 10yds. quartering hard. Arrow enters behind last rib & comes out just behind off shoulder, broadhead pass thru not complete. Second deer was a 165-170lb. 13pt buck perfect broadside at 23yds. Arrow enters 3" behind shoulder center mass, in my opinion a perfect shot, broadhead goes thru both lungs but doesn't exit the cavity only one hole. Third deer doe slightly quartering. Arrow enters behind shoulder and exits thru off shoulder, broadhead pass thru not complete. This year I have shot 4 deer. First doe broadside 17yds, arrow enters behind shoulder & exits behind off shoulder. Broadhead barely made it thru the hide on the offside, but it did. She didn't go 50yds. #2 was a doe 17yds broadside (standing almost same place as first) I held alittle tight to the shoulder because of a limb. I pulled the shot about 1" and hit the edge of the shoulder, only got 5-6" of penetration. Knowing I only got 1 lung from lack of penetration I gave her a couple of hours. The weather man was off on the rain by about 4 hours, after about 100yds. the rain washed the blood away, never found her. The 3rd deer was an 8pt. weighing around 150-160 broadside 20yds. I had my new hoyt this time. Arrow entered 3" behind shoulder & exited same but lower on off side complete pass thru. Deer only went 60yds. 3rd deer was doe broadside 18yds. steep angle. Arrow went in a couple of inches behind should and exited arm pit on off side, complete pass thru. Here is the weird thing, I had a huge entrance hole (rage standard) but one of the blades broke off as it was going thru deer and the other just folded up. The exit hole was barely big enough for my pinkie to fit in. She only went 50-60yds. and fell. there was almost no blood until a couple of yards from where she fell. I have read lots of reviews on these heads everywhere, good and bad. I've heard they open in flight, break, don't open, don't penetrate. here is my opinion for what its worth: I really don't think they will open in flight if you make sure the blades are snapped into the rubber o-ring, and not just mashed in. The blades are alittle flimsy and I typically replace after every kill, but this is the first time one has broken on impact, which has caused some serious concern. I think they will always open no matter what kinda critter you shoot, its how there made. I have determined that you need a bow with some pop to get a complete pass thru with these heads if you hit any kind of bone, which I have now. All that being said I will finish out this season with these heads but may change to slicktricks or G5 strikers next season. After the last deer I shot I'm just not convinced that they are as bullet proof as I thought (compared to a fixed head). I'm not sure what happened when I shot the last deer but when I gutted her I noticed one lung had that huge hole the other had a small hole. Leading me to believe that the blade fell out between lungs. They are a awesome head when they perform properly, I really like the holes and blood trials you get with these heads, but there is a chance something could not function as expected and cause a problem. I'm fortunate that I made a good shot on this doe, if she'd went out of sight with no blood I might not have found her. Not sure what I will do next season, I haven't lost many with a bow and I don't want to every lose another one if I can help it. It may happen but I don't want it to be my equipment.
