speed of my new bow
 

i am getting a new bow at 50-55 DW and i am shooting around a 350 grain arrow, what would a est. fps be?
thanks

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.

Fred bear instinct DL 25 ibo is 306 i think.

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?

RE: speed of my new bow
 

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.

RE: speed of my new bow
 

would arrow wraps give me some extra weight that would help?

RE: speed of my new bow
 

wraps would add more weight, but only 7-12 grains. They would also lower your FOC.

Try inserts behind the broadhead to add weight, or try some heavier broadheads. I know you can buy 125 and 175 grain broadheads. These will really raise your FOC and should help w/ the KE.

RE: speed of my new bow
 

150 grain broadheads would put you up to 40.31 ft/lbs
175 grain broadheads would put you up to 43 ft/lbs
200 grain broadheads would put you up to 45.69 ft/lbs

all of this is rough, it's hard to tell w/out knowing your arrow velocity, I used 220 as a rough guess.

Plus 200 grain BH's would put your FOC probably around 20%, depending on shaft length/spine size.

RE: speed of my new bow
 

NO. I've gotten passthrus with 33lbs KE with Wasp SST Hammers. Trad guys are successful with less. Honestly, your setup is ok for whitetail. If you wish to increase penetration, the first thing I would do is go to a 2 blade cut on contact broadhead. Be forewarned, however, you may have to change to helical feathers to keep those heads under control. The feathers will also increase your FOC slightly.

as long as my setup will work good for whitetails i am ok, that is all i will be using it for.
