Arrow weight

<< < (2/4) > >>

Juniper:
I only adjust my nock point for one thing.  Straight arrow flight (no porpoising, sp).  I think you could change your point of aim/impact with higher or lower nock point, but you would be risking bad arrow flight.  I also don't like to switch back and fourth between heavy and light arrows as it will effect your shooting.  I like arrows around 500gr and try to stick as close to that as possible.  100 grains will make alot of difference in point of impact, aim, etc. especially at longer ranges. 

Kegan:
Thanks for the input guys!

For the nocking point, I think it will be, as Pat and Pappy suggested, a matter of experimentation as I go. I just wondered as many of the modern fiberglass bow shooters I've seen nock rather high, and most of them are using carbon or aluminum arrows. After trying it out with my brother's arrow (700 grains) it seemed to make a big difference- in that I actually hit the target :D. Since spine affects the left/right, and weight affected up/down, I wodnered that just adjusting the arrow so the rear end was slightly higher than a heavier arrow would "compensate" or something.

As for weight, I was worrying about going under the 10 grains per pound rule of thumb- which I've come to belive was an almost requisite for traditional bows. I enjoy shooting out to 55 yards at times on targets also, but my heavier arrows land in the dirt half the time, so I was interested in trying lighter shafting (which also has the benefiet of being less work :D) for arrows. Pope and Young and Howard Hill shot lighter arrows in the 600-700 grain range which confused my further, and led to my asking here.

Pat B:
With bows as heavy as you are shooting, the 10gr per # rule isn't necessary for good penetration. When dealing with folks shooting bows in the 45# to 50# draw weight for hunting they would definitely want at least 10grs per #.   For hunting, all you need is about 6" to 8" pf penetration to kill the animal and even less for a heart shot. Anything beyond that is over kill(so to speak ;D) and is not necessary to kill the animal...deader.    Having the arrow come through the other side will help with tracking as will a pass through shot but they are not necessary. It is more critical to have an set up that you are confident with enough to put the arrow where it needs to go at the distance you are shooting.   Pat

George Tsoukalas:
I like 9-11 grains per lb for all my shooting and don't change this for the type of hunting I do. Heaviness of the arrow does affect spine but the question is how much. If the weight is distributed over the entire arrow arrow the effect is less. If the weight  is more upfront as in footed arrows the impact is greater. It's tough finding heavy arrows for a 80# bow. Sometimes you gotta make do. Jawge

Kegan:
Thanks again guys! My mind's at ease now about testing lighter arrows. Thanks for all the help, now all I gotta do is wait until they arrive and start testing :).
