This happened to you? If so, you're doing it wrong. If not, you're just making shite up like all the other small-brained mech haters. It's truly sad we have so many here who apparently just cannot think for themselves.
I tracked a deer that my cousin shot with a rage (quartering away) and one of the blades broke at the rib. The blade was stuck between the bone where it broke and the lungs had a 1 inch cut. It was pretty obvious what happened. It doesn't take a masters in engineering to know that an unsupported 1 inch piece of steel isn't going to be as strong as a 1/2 inch piece of supported steel.
I have tracked a deer that was shot by a rage that didn't open. Fortunately it was shot through the heart and we found it. Did the guy "do it wrong?" I don't know, but he's a master electrician that owns his own business so I figure he has enough sense to use a Rage broadhead.
I bought a pack of rages when I still shot meat seekers and they rattled and would deploy in my quiver. I never shot one at a deer and gave them away.
I'm not making shite up and I don't know how I "could be doing it wrong" when I took them out of the package, screwed them onto my arrows and put them in a quiver designed for mechanicals,which I might add, had no issues with the Meat Seekers.
