Too many variables. What bow? Draw length? IBO rating of the Bow? You can't beat just firing it over Chrono and then you know for sure.

Well for each inch of draw length reduction you will lose approx. 10 fps, and foreach # of draw weight under 70# you will lose 2 to 2.5fps. I would say from what you are giving me your bow will shoot a 350 grain arrow at 55# approx. 219fps to 226fps give or take.

ok that sounds good to me.

i just added that into a KE calculator off of goldtip's website and it said that i would have only 37 (rounded) foot pounds of KE which isnt enough to kill a deer according to the calculator it should be 40 and up. am i doing something wrong?

I think I just came up with 39.7#KE but all this is hypothetical at this point. Your setup would be adequate for Whitetails of that I'm sure. A heavier arrow and higher FOC will give you better penetration on a borderline setup.

Indian's killed deer with a stick, string, and sharpened rock.

I am sure your highly advanced compound bow will do the job, lol.

^ that is true, i was just going by what the calculator was saying.

technicaly if i did it right, most people who want speed go 5gpp and am going by 6gpp and my arrow is still 20 grains heavier then the 6gpp, and what could i do to get the higher FOC or heavier arrow weight? i am already using a heavier BH.
