Iam Sure you will do well Robinhood, At least I wish it so for you.

Yes many big animals have being taken with the grizzlys', so I don't think you have to worry about it, it also shot placement, Right?

I just believe from also butchering animals for eating, when I was younger, that a broder blade has a better chance of finding a vital artery or vein, at least that is what I was taught in South America ,where my parents had gone to be missionarys for many years.

We had to learn to butcher animals with a knife, I experienced that a thin long tip knife tapering back to a wider blade did the job quicker.

So I figure when you are arrowing an animal the same principle applies, a thin tip widening on rear has a better chance of finding a vein or artery.

also there is in my opinion a misconception that an arrow that passes through is a quiker kill, and i say an arrow that stays with the tips in the vital area, makes the animal move and run or walk, that tip is also moving back and forth and slicing the lungs or heart, I guess the thing is placement shot and sharpness.

I wish I could post a pic of my blades, but I don't know how to do it in this forum.
If you walk me through the process I could.
Thanks my friend, good hunting.
