Home Forums Hunting & Shooting Bowhunting Arrow penetration on moving targets

Correct, those high powered, shoulder discharged weapons are very powerful and fast and won't likely react like the weapons bowhunters use but this exercise is geared to bowhunting and not crossbowing (or whatever that sort calls what they do). Perhaps a crossbow will do a similar activity.

Useless statement, designed only to irritate. Crossbow bolt and arrow are only simple variations of the same thing. Many longbow have higher poundage than lower end crossbows. If I recall correctly, up to 180lbs vs 150lb on your standard crossbow. All archery projectiles have to follow the same laws of physics. The Archers Paradox is The same for both, horizontal or vertical. The only REAL difference, is how the string is held. (Which has NO effect at point of impact. Any force that applies to one, applies to both, to a greater or lesser degree, only.

You are covering ignorance with deflection, with the intent to irritate.

You forgot to critique his comments.

Im guessing you missed it. Here it is.

Paradox is the arrow flexing around a bow (non centershot)......and should not be confused with other arrow flex.
You do get arrow flex with centershot rigs, fingers side to side mostly, and releases up and down..........but the arrow has a straight path through the bow..

There is paradox on some rigs, and all arrows oscillate.

Animal movement and lack of penetration would IMHO be from........

tissue/structures acting as a brake (pinch).
tissue/structure deflecting the arrow
tissue/structures acting as a stop (partial or full)

Eh, I usually blow through my deer, even with recurve.

My point was, both horizontal and vertical bows have to answer to physics. And at point of impact, there is no difference to either arrow or bolt due to HOW the missle is thrown. Only to what lateral force is applied by movement. The length, diameter, and stiffness of the missle are the only real variables in the missle. Speeds can be match with both types.

According to the laws of physics its impossible to avoid some degree of real world deflection from
the perpendicular (Angle of Incidence) even on a stationary target..
Maximum possible penetration would require no deflection from the perpendicular( zero Angle of Incidence)
and zero Angle of Attack.,,,as well as no shaft flex.

But with such a primitive study, How does one accurately and reliably determine if any loss of penetration
was [more or less] due to factors like variation in AOI , AOA and shaft flexion, rather than primarily from
the degree of arrow shifts from the perpendicular as influenced by the moving test material?

Arrows do not track straight to a target
Arrows flex through a range of shapes during flight
Arrow Angle of Attack and Angle of Incidence
need to be considered and factored in.

Arrow AXIS and TRACK (direction of travel) typically do not align in the real world.

Have wondered about higher FOC..........helps with arrow flight, got more momentum.......does that added bit up front lessen deflection?
I don't up FOC by tip weight alone, use inserts behind my standard tip to get my spine right, so the front of my arrow is stiffer.

Also........some concern on thinner walled shafts and inserts.........crush.

Never experienced it. Added inserts give more glue contact though.

Didn't have it on reg arrows (xx75 or GT carbons)........reg 125gr tip and alloy insert.

Just blow on through.
