Title: Physics Question
Post by: nightowl1 on April 01, 2009, 10:15:00 AM
I was measured when I first started shooting (2 1/2 years ago) and my draw length was 28 on the dot. That was with a 50 pound and 70 lb bow. I did the clothes pin method yesterday and I was varying somewhere around 26 with my 55-58 lb bows at 28".

So my question...Would it be better to shoot a bow at 50# @28 or 50# at 26"?

I say this because I think I like the 50 pound pull and am just compensating my form to shoot at this weight haha does that make sense?

Everything else being equal, the 50# @28 will perform better than the 50# @26

Can you hit the 28" anchor consistently?  Do you get good arrow flight?

If so, there is no reason at all to shoot a 26" draw.

28" gives you a bigger power stroke, but as Jeff said, you have to control it.

50@28 will shoot something like 57-58@26.  There is a big difference in performance in two inches of draw length with most bows.

Depends on what you are doing. Inside 30 yards, 50#@28"...Over that, 50#@26".......O.L.

You probley are more relaxed at 26"s inchs than 28"s.If so what makes you think you would shoot better at 28"s.Sorry your arrow won't fly any better.It maybe alittle harder to spline and you may lose a little weight.Small things to lose to shoot brtter.
 After shooting awhile some people relax into a shooting form and lose a little draw leanth.

yup, what Roy said.  I started out shooting 29" and now draw 27" consistantly when I shoot now, and am comfortable there.  sourowl

Lots of things could change, my draw length shortened after I got job at UPS my forearms got really big, and had to bend my arm more so I would not sock my arm with the string, so that is my experience, strength and hope!!!!!

Ok OL, I'll ask, Why is 50@26 better farther out, it has a 2" shorter stroke.

I'm so confused    :help:

Now try this one ... 50@28 with an 6 inch brace height and 50@26 with an 8 inch brace.

Just for fun, make one string 10 strand and one 16 strand.

And more fun, shoot one bow on the top of Mt. Everest and one in Death Valley.

Too much fun?

TonyW LOL...You're strirring up too much trouble. You forgot hot and humid or cold and dry.

King, you're asking me to turn loose long distance secrets! With the same arrows 28" would have the advantage. But if the arrows were optimized for each bow, the shorter arrow will leave the bow with less horsepower but less drag. The 28" "faster" bow will bleed off energy at a faster rate so the short draw/arrow will quickly catch it and maintain what it had further. My wife taught me this, I'd have a weak arrow at my 30" draw, whack 3" off of it for her and she'd kick my butt with it. I know it sounds counter intuitive but very true.....O.L.
