Not a condemnation, but a recent experience....
I have expressed concern to my dad about his desire to shoot mechanicals and last night he finally understood. He is shooting a Z7 at ~57lbs; Gold Tip arrows that are about 7.3GPI. With 100gr points his total arrow weight is ~330GPI, but it's quick
I've shared with him that I believe his setup is not good for mechanicals and he should shoot a cut on contact fixed blade. He just started bowhunting again last year after about a 30yr layoff. He killed four deer last year shooting slick tricks. All four were pass throughs. One deer was a southern Illinois buck weighing about 175lbs.
Last night he shot a 130lb deer at a slight quartering angle. The back rib was the only bone involved, but it was not a direct hit. He did not get a pass thru. He got a far side hole, but when we recovered the deer the arrow was hanging out both sides.
After the blood trail, celebration, drag, quartering, etc. last night I mentioned to him that I was concerned about his arrow penetration. He's going to northern MO in November to hunt and if he shoots a big deer with his setup I don't see any way it will pass through.
This morning he handed me an unopened pack of Rage 2 blade BHs and said he's going back to slick tricks and now understands why I've been against them.
Before you ask, his bow is well tuned and is shooting bullet holes
I do believe there is a place for these large cutting mechanicals, but they aren't for everybody.
