He says he uses one pin all the way out to 50 yards, but beyond that his arrows do not have enough energy left.

He has to change strings at least 2x a year.

I heard from a coworker that when he shoots it sounds like a gun.

Yesterday he asked me where I shoot and he said he had noone to shoot with, and he wants to get together and shoot sometime. A little friendly competition? I gotta get the shots for my back first b4 I can pull my bow. I hope the shots work.

Krisken,

I do not mean to be argumentative but this is not necessarily a true statement. For example....

A 60 lb bow shooting a 300 grain arrow might have a hypothetical speed of 260 fps. Then, lets look at the same hypothetical bow shooting at 70 lbs with a 350 grain arrow. When you increase bow poundage you will have an average gain of approximately 1.75 fps for each pound of draw weight. That would mean a speed increase of 17.5 fps for the 10 pound difference in draw weight. But since you are increasing arrow weight by 50 grains to keep the ratio at 5 grains per pound you also need to subtract approximately 10 fps. If we combine the two figures then that results in a net gain of approximately 7.5 fps by increasing draw weight by 10 lbs while maintaining the 5 grains per pound of draw weight ratio.

A more accurate statement might be that increasing draw weight doesn' t offer a significant amount of additional speed if the person maintains a 5 grains per pound of draw weight ratio.

I did not want to seem like I was lecturing but this is a commonly misunderstood issue.

who said he was shootin five grains per lb. I can deviate from the rule and shoot a light arrow weighing 244 grains and get 287 feet per second out of 52 lbs and 27.5 inch draw. My buddy shot the arrow from his 72 lb pull and got 315 feet per second once.

Are dual cam bows generally faster then a single cam??

What' s the trade off in design differences?

Krisken,

I do agree and said as much in earlier post....ie...." ...doesn' t offer a " significant" increase in speed...." .

But then there is Kinetic Energy numbers.....

..................

...and I also agree that current dual cam designs are faster than their single cam counterparts. That was not always the case until Bowtech came onto the scene.

I would also worry about someone that needs to change their string/cable setup twice a year. I do not think that the gain is worth the effort.
