Kinetic energy/broadhead question

[ChickenWilly]

Just got my new bow a couple of days ago and was curious what my kinetic energy would be. I got the mission Blaze and have it set at 52 lbs and I'm shooting easton axis 400s out of it. My arrows are 27.5 inches long from the end of the arrow to the valley of the nock and I'm shooting 100 grain heads. Without factoring in the weight of the nock and the blazer veins I figured it up to be 347.5 grains. It shot 242 fps through the chrono. What would that make my kinetic energy? And would the grizztrick2 broadheads I was shooting with my old bow have to steep of an angle on the blades to shoot out of it? I was shooting closer to 280fps out of my old bow at 70lbs. Thanks in advance !

Quit worrying about all the K.E./ Momentum B.S. and just kill stuff.

Aprox. 45# k.e.

I shoot the same arrow, same length with blazers and 100 gr heads. They weigh like 393 or 394 gr

I agree and disagree with rocky. K.e and momentum has it's place in archery. But your good just go kill something. That was the agree part.

I know I can kill stuff, I'm not worried about that I was just curious is all. Mainly wondering about the broadhead thing. I know those heads have a pretty steep angle on the blades. Really think I'm gonna get some razor tricks though !

[enewman]

I cannot tell you if you have enough for that broadhead. I'm sure you do. A long narrow head will usually penetrate better. A sliver will always slide in easier.

I can't tell you that the slick tricks you are pushing will do what you want with your setup, but I can tell you will all certainty that if you go with Ramcats out of that setup you will kill what you shoot at. Period.

You are right, both are a measurement of penetrating potential.
Both are simply formulas.
There are other variables that reduce penetration that outweigh K.E.
If I shoot a deer in the butt muscle, I'm gonna get less penetration than if I shoot it through the chest cavity.
If the deer ducks or twists while the arrow is in-flight, or at impact, I'm gonna get less penetration.
If we're simply talking about deer, (larger animals differ), my wife's set-up keeps things in perspective for me.
She has a 25 inch DL, pulls 42 lbs, shoots an arrow that weighs under 300 grains, and shoots through deer.

I know you enjoy playing with arrows and tuning methods as do I, and as I have on many, many different bows, DL's, and requests from individuals as to heavier, vs faster.
Lots of guys walk into my shop asking questions about some article about tuning or arrows that they read somewhere, and as I go into detail, It quickly gets over their head, and they walk away more confused than when they came in.
In most cases, the equipment they have will kill anything in North America,
and they simply need to go kill stuff.

Yes sir I agree with you. But do they walk away confused or is it that they don't give a crap. I see that a lot. As long as they can hit a plate there good. Same people are the ones that shoot a animal and don't care if they find them or not.

And you are right about what your wife is doing. I have a friend that his daughter ,that kills all kinds of critters with 40 lb and a lite arrow. Sure makes me wounded why I waist my time.

I agree with rocky, don't put too much worry into it, just hunt logical and keep equipment in good shape, you'll have the KE you need.

Main thing, don't go around wounding everything. I am one who doesn't believe in "speed is everything". Sure, 460fps is fast, but if you have a 85gr tip and can't even break at rib at 40 yds, what the heck good is it?

At 52lbs you are good, in fact I did better with a 125gr tip under 60# than I have with 70# & 100gr

Enjoy your new bow, my brother is looking at buying one of those!

I have to agree with Rocky. I find we as hunters tend to "overthink" the problem. I used a CE Pile Driver Pass Thru Extreme and a Montec 125gr head to shoot a hog using a 55# draw bow about a month ago. I was worried about arrow performance, but I should have just accepted what I had. I killed a 135 pound hog at 18 yards with a complete pass thru with a quartering away shot left side. Lesson learned..Hit the woods n kill stuff..end. period. dot.
