I've used several mechanicals over the years.

Punchcutters

Rocket Miniblasters 3L

Wasp Jak-Hammers

along with several fixed blades

Thunderhead 125's

Satelites

Wasp Cam-Loks

Muzzy 75's


I've taken many deer with each head. I've taken most with Rocket Miniblasters. Not sure how many but probably around 20 with just that head.

I never had one fail. I will say this, Every time I shot a Rocket mechanical it would severely bend the blades or break them off. They were only good for one shot.

Idid read somewhere, that the Rocket blades were designed to bend and break as to not stop penetration. They wanted the arrow to keep penetrating and not to get wedged and stop.


One other problem with some mechanicals is on very sharp angles. They will slide along theyrib cage, instead of penetrating sometimes. Ive had this happen twice.

Below is a pic of what a Rocket did on a sharp angle. It really sliced open a heck of an entrance wound. Yes, that is the entrance wound.
