I use the 125 gr. 3 blades and haven't had any troubles. I shot 4 bucks and three does so far with them. I haven't had complete "stick in the ground" pass throughs, like my old Bear Razorbacks, But they have penetrated both sides of the deer, just not punched out the other side. They fly too true to be true. The only problems I have had was poor shot placement on my part. You'll like them
Good Luck
