Everything I have hit with them has not made it more than 100 yards. But they can open in flight or before you shoot causing your arrow to miss or wound and animal(I was lucky to only have the first happen). I switched to ulmer edge and love them. they fly like my fieldpoints and don't have opening o not opening problems

my friend shot tryed shooting a deer with them. he said the shot was a little high but would have killed the deer but when the arrow hit it flipped over the deer a kept spinninguntil it hit a tree. he said he is going back to fixed blade for the next season

I used them for a couple seasons and had a whole host of problems. Shot a few deer and turkey with them but performance was poor, very poor.

I have used them for 5 years, 2 & 3 blade versions. Their latest ones with the new plastic lock collars are a great improvement on the design. I shot 4 deer with them last year and none went more than 50 yards, most 30 yrds, and two were liver shot. All bled out quickly and cleanly, even the two liver shots. My 11 year old daughter took her first deer at 23 yards with the old three blade version with her Mathews Rage bow set at 35 pounds of draw. She took out the right lung and punctured the left. Deer went 70 yards and tipped over. I am very careful with them and check them often while on the rest. They aren't without their issues. They DO however fly GREAT. Buddy of mine took a 850 lb bull elk with the new 2 blade at 25 yards, went 70 yards.
