So... dead is dead, and any gear will do that, but augmenting it with a little larger head is very helpful when the vitals are so small and the best plan of attack is to do a great deal of damage. Now this only works if you can still put the arrow where you need to.
I use large thee blades all the time so that is not really a change. However for no apparent reason, i go back and forth from the VPA three blade to the BigJim thee blade (same head, but much wider) when hunting deer and pigs.
While hunting turkeys, I exclusively use the BigJim head... Turkeys can't tote it! Of course, it flys like I want it to, or I make a gear adjustment to get it to. Given the opportunity, I shoot the birds in the hips.. A bird that can't run, can't fly... and he can't run.
I would say that I have never had a bird shot in the hips get a way.. or even make it more than 10 turkey steps!
Have only had one bird go more than that distance, and it was shot in the back barely missing the spine.
Only birds I've lost were birds I never hit. Now in fairness, I've only kilt 9 of them ..so far.
This year I'm going to attempt a slam in a single season.. just because I like to go to different places. I have arrangements with a friend in Florida or Osceola's. Lots of eastern here where I live, and traveling to New Mexico in April to a friends place teaming with both Rio's and Meriam's. Of course going don't mean it will happen.
I'm going to need a little luck too!, BigJIm
