Couple of notes:
Mechanical broadheads are legal per the 2016 posted hunting regs on the WDFW site.
I did some testing on these broadheads since I moved to WA in the last 18 months.I was first very disappointed that crossbows are not allowed during the archery season in WA, so I switched over to a compound bow to continue to take advantage of the longer season. I was concerned about the slower compound bow not properly activating my mechanicals, so I purchased some of these Toxic broad heads (as well as some cheaper knock offs for target practice) and have been comparing them to the accuracy of my field tips. I was gaining confidence with the broad heads as I was practicing almost daily in my backyard range @ 30 yds, but when I started using the Toxic, I was unpleasantly surprised! At 30 yds, they are consistently 6" + off target, but inconsistent in which direction they are off target....this is completely unacceptable. As an engineer, I felt that the curved design would be less affected by planing and therefore more accurate...BOY WAS I WRONG! After a full month of testing, I still cannot obtain any accuracy with these broadheads and I am glad I didn't take them to the field.
I am going back to the Grim Reaper Mechanicals I used with my crossbow, and I also applaud Grim Reaper for providing a practice head with each package of 3 mechanicals! makes dialing in the bow so much easier!
