I shoot a 100 grain broadhead for deer and was wondering if that would be alright for pig or if I should go 125? With good shot placement will 100 g do the trick?
I am sure this will get moved to the bowhunting forum, but the weight difference doesn't matter if it isn't tuned to the arrow and bow setup, it is more complicated than asking if a 25gr difference will be better for hogs, out of my bow 100gr is trash, makes my arrows too stiff and the arrow will be all over the place, 125 is my weight.
Now all things considered being good to go, a heavier shaft will penetrate better since it holds it momentum better, to a certain point that is.
So the question is, will your arrow be within specs with the heavier broadhead? Also more weight up front stabilizes the arrow, ever try throwing a spear with the weight on the back end? Doesn't stay in flight long at all.
If you're getting good pass-throughs on deer with that 100gr broadhead, it'll be fine for hogs. You can step it up if your setup will bear it, and it may be a little benefit in the event you get a really big hog or a less than perfect hit.
At risk of drawing down the ire of the physicists in the crowd, a safe and simple axiom is, "Increase the kinetic energy, and you increase your effectiveness."
Will your arrow spine handle it? You don't need to change if you are confident in your current set up and like the way it flies. Plenty of hogs have been killed with a 100 gr head. But there is a lot more to the equation. What is your total arrow weight? Do you know your arrow speed? Give us a better idea of your setup.
I'll take momentum over kenetic energy anyday. Wind resistance quadruples as speed doubles, so fast arrows lose energy faster than slower, heavier arrows. Fast arrows are also more susceptible to tuning problems so they are less forgiving. The one benefit to faster arrows, of course, is less compensation is required for greater distances, but you still have to compensate.
For heavy, thick skinned animals, I'd go with the heaviest set-up you can while still being able to hit the vitals at an acceptable range.
Staying with the same weight head for everything will simplify much of your tuning and shooting work. If your overall arrow weight is OK at 100 I would not change it.
The word "axiom" comes from the Greek word αξιωμα (axioma), which means that which is deemed worthy or fit or that which is considered self-evident. The word comes from αξιοειν (axioein), meaning to deem worthy, which in turn comes from αξιος (axios), meaning worthy. Among the ancient Greek philosophers an axiom was a claim which could be seen to be true without any need for proof.
come on spec......I'm just a humble 6th grade gradiate.
I've had several chances to stick a hog in the last 2 weeks......first chance I had I had 4 big hog's below the well house......I was 20 yards from them and it was so hot they weren't going to come out of the water....I even went so far as to go get my bow....but realized that my tag expired the weekend before...LOL....every other time I was busy doing some work on the place and passed up the chance.......oh well....I enjoy helping these guy's I work with who never killed a pig get one........I do have a guy here that want's the meat so if the right opertunity presents itself I'll do my best to stick one......I'll be up to the club this weekend chasing deer..last year I was in bow range on hogs several times during archery deer season so ya never know.
