Better bow perfomance

[sssurfertim]

I shoot a 3 yr old Martin Moab single cam 70lbs with Beeman camo hunter shafts with standard vanes(340's I beleive).  I wanted to get a bit more speed out of my bow, would better arrows or smaller vanes be better?  How does everyone feel about the "Blazer" vanes?  Im going to start fletching and cutting my own arrows this summer.  Also would using a non camo shaft gain speed?  I feel the camo dip on the arrows add some weight.

Blazer vanes are fine . I was using them until I tried the 4" Qwik-Spins and changed everything . I also shoot a heavier shaft . Speed isn't everything ! I'd rather hear my arrow go "thump" instead of "thwack" !  ;D

The weight on arrows is measured in GPI (grains per inch) with factors considered including material, wall thickness and shaft diameter. Different Beman 340 models have different GPI weights.

  A lighter arrow will be traveling faster as it leaves the bow, but will slow down quicker than a heavier arrow. Thus having less speed at point of impact (unless a point blank shot). Then the arrow spine comes into play which would affect accuracy as high force of air is placed on a faster (lighter) arrow.

There is a good article on this  http://archeryreport.com/2011/01/heavy-vs-light-arrows-speed-power/ 

Hope it helps.

I shoot Bemans ICS Hunters, 340's. My bow is set at 66 pounds with a 29 inch draw. It's plenty fast enough.

As long as you're shooting well with them I wouldn't change anything.

That's a good point. I would hate to see you mess up a good shooting set-up chasing another foot or two per second. Just make sure that what ever you do you can backtrack to whatever is working now (assuming that your accuracy and consistancy are good now). I've seen guys get into all kinds of problems in pursuit of speed.

Right on , if it works , don't fix it !

70 lbs pushing 2315's aluminum camo hunters and 100 grain broadheads. Anything out to 25 yrds hasn't been able to get out of the way fast enough yet.

I have shot almost all the newer 2 inch BH vanes and they seem to work as well as the old 4 inch vanes with BH or Tgt points. But again if you are getting good arrow flight and it is also a forgiving setup I sure would not change a thing... As a bow shop owner I sure over the years found some guys just want speed and then they get just crap. I go by the kiss way of doing things...Keep it simple stupid... why mess if you got a good setup. The other is speed kills if you have any archer faults as you shoot. A bad relese with a very fast bow may mean up to 6 inch change at 25 yards. The other I found over the years is a heavy weight shaft / BH setup will give you so much more peneration on game. SO I use carbon arrows with 125 gr points, a little slower but I get the same peneration I use to get with 2117 alum in years past. I use Bemen hunter shafts with 2 inch vanes.

Thanks for the input, I definetly need heavier arrows because I can see the fly arradically even though its hitting its mark(the fletchings kinda go side to side after hitting into the target).  I will probably come down on the weight a bit because I feel my arrows hit harder when my bow was set for 64lbs rather than the 70lbs im shooting now.  Quickspinns would probably help stabilize it also.

Your very right, my buddy is always commenting on how much faster his bow is than mine bla bla.  My arrows do hit very consitant and I really have not seen any difference when I increased the speed other than my arrows are more unstable in flight.  Ill definetly be going back to 64 otr 65 lbs.
