arrow drop at 20 yards

[10point]

I'm currently shooting 2 recurves. One is 43/44 lbs and the other is 52 lbs. Same arrows with each bow ( about 450 gr total). nock point is the same. The 52 lb seems to hit about 3 to 4 inches higher at 20 yards. Does the extra 8/9 lbs result in a flatter arc or could something else be causing this??? Just curious what you all find when increasing draw weight.

If you're shooting the same arrow, it stands to reason that the heavier draw-weight bow will shoot flatter and therefore impact higher at 20 yards.  The thing to consider is that it's unlikely that the same arrow will be well tuned for each bow.  It is likely that the heavier bow will require a stiffer and perhaps heavier arrow than the lighter bow to perform at its best.  People often find that when they tune arrows for different bows, the increase in arrow weight for the heavier bow cancels out the increased poundage of the bow, causing the different arrows to impact in more or less the same spot for the different bows.

All thigs being equal (same arrows, release,etc.) the higher the draw weight the flatter the trajectory.

"X" Grains per pound at a given draw weight will have the same trajectory.

i.e. = a 45 pound bow shooting a 450 grain arrow (10 GPP) will have the same trajectory (darn close to it) as a 650 grain arrow (10 GPP) out of a 65lb bow.

Have fun....


It's all math and dependent on the projectiles being the same.

You can shoot the same arrows in different bows if you tune the bows properly.

Also, arrow impact depends alot on the bow and the shooter.

I ordered some 53# limbs for my SA11 years ago after i broke my back and dropped down from 59#s.

For some reason, the 53# limbs on my SA riser would shoot higher than my 59# limbs and i couldn't get use to the lower poundage limbs.

I dropped to 46# with my TF11 and shot as well with it as i did with my 59# SA11.

I've had bows here that range from 44#s to 60#s and i can shoot the same GT3555 through each bow.

You can buy arrows for each bow, but if you have several it can get expensive. Learning to tune the bow to the arrow can be challenging, but fun if you don't get aggravated doing it.
