I used the Montec 125's last year and shot two does with them. One made it about 70 yards and the other 50 yards. Both shots were complete pass throughs and blood trails were good. They dont feel as sharp as the replaceable blade heads but G5 said they sharpen them at a different angle to make the edge more durable. They were plenty sharp enough to do what they were intended to do on the deer I shot. Mine shot about 4 inches to the left of my field points but they grouped well and the arrow flight was good so I just moved my sight. I will be using them again this year.
