Arrow speed

So I just had a tune up done on my bow and they weighed my arrow and got my arrow speed for me. So my question for everyone is my arrow weighs 388 grains and is flying 280 fps is that good bad or average? And is that an ok arrow weight?
 
Depends on what your trying to accomplish imo. I assume this would be a hunting arrow? For example... My set up i have now is a 405 grain arrow going 297 and producing about 79 lbs of kentic energy. My old set up was a 477 grain arrow going bout 275 and was producing bout 80 lbs of kentic energy. Imo it wasnt worth the 1 lbs of added kentic energy and losing almost 26 feet per second. Of course there is a number of other things to factor ( broadhead, animal your shooting at, distance, ect). What im saying is there is alot to take in account so you kinda want to play with it. I dont think i would shoot a big expandable with what your set up just because it takes more energy to push a bigger hole. I try to make my setup good for deer and elk cause thats what i hunt for most.
 
Get your popcorn. This is a subject where you will get all sorts of answers imho. Ive seen people say on other forums that your using to light of an arrow. You cant use expandables, dr. Asbe says yada yada yada.

The real fact is anytime you can shoot heavier and faster arrow the better period! But not everyone can shoot a 33" draw and 700 grain arrow over 350 fps.

The good news is your arrow and speed your shooting will fully penitrate any animal in north america with proper shot placment. It will also do it at distances beyond what id consider most people should be atempting.

Your setup is faster than mine! ;(
 
My arrow is 350 grains and my draw is 28. My arrow speed is 322. I like the speed. I know alot of guys that are all about KE and a few other things, but this is me. SPEED>
 
There is one draw back to a light fast arrow. It still requires the same size fletch or slightly larger to control the broadhead especially if yout using fixed heads. Its side affect is an arrow thats speed degrades faster. The faster the speed degrades the worse your groups get at longer distance. In essence your arrow acts like a flu flu arrow.

Fita shooters use a heavy skinny arrow with small fletchings with very little helical to try and eliminate the parachuting effect.
 
As long as you hit where you want and have a good quality broadhead you'll be fine. It wasnt that long ago guys where killing the same animals with big heavy alluminums and sub 250 fps bows. They killed everything just fine. I personally feel confident with an arrow between 420-440 and try to get over 280 just for a little flatter trajectory. Go with what your confident in.
 
There are some that say shoot a light and fast arrow. There are some that say add some weight and you're better off.


IMO kenetic energy (KE) is NOTHING to worry about. I focus on Momentum.

Momentum = Mass X Velocity



I believe that no matter how many Ft/lbs of energy (KE) an arrow has it doesn't guarantee that arrow will penetrate effectively.


KE doesn't punch through the shoulder of an elk at 50 yards. Its the momentum the arrow carries 'through' the animal that you need to worry about.


We aren't shooting bullets with 3000 ft/lbs of energy.



The way I try and explain this is if you took a 5gr pebble and shoot it at 5000 fps you'd have 277 ft/lbs of KE.


Now slow it down and add some weight... I shoot a 420gr arrow at 280fps giving a total of 73ft/lbs of KE. By the KE theory I should be shooting the tiniest projectile at the fastest speed possible.


When you deal with momentum the pebble would only have a 3m. With the arrow set up I'd be right around 16m.



I believe there is a good balance between speed and weight. If you go to heavy you loose distance. if you go to light you'll loose distance. Find that happy medium and kill a monster.
 
Yes there are options for all. With me set up, I shoot a 360 grain arrow @ 320 fps, that is equal to 82 #'s of KE. I use gtip arrows xthunter and blazer vanes and I shoot G5 strikers. I hit identical at all ranges. I practice up to 100 yards. I have never shot at an animal at this range, but it makes the close shots seem easy. Last year my 50 yard shot on my muley seemed easy. Now a 175 is on the wall.

Like others have said, shoot what is good for you. My setup has worked good for me.
