A 2003 50-60 lb( set at 60lbs) Bowtech Patriot Dually, 27" draw shooting 27" arrows weighing 373 grns would fly? I just won one on an ebay auction and was wondering what it might produce speed wise?

About 265fps

Really only 265? I was hoping for more, oh well its gotta be faster than my Reflex Grizzly.

Maybe slower. Your shooting 27 inches, at 60 pounds, and 6.2 grains per pound....don't know what you have on your string to slow it down more....but that's probly about right.

The reason I said 265 was my 03 Pat Dually 60lb 28" draw with a 375gr arrow shot 275fps so minus 10fps for your inch shorter draw lenght.

geez, I feel bad. My hoyt is three years old and set at 60# and shoots 6.8 grains per lb and I am right about 240. accurate and well tuned little sucker though.
