what is the formula for calculating kinetic energy? i've never heard of 386 fps. are you sure? what kind of bow do you shoot?

thats crazt.........But.........I dont know about that. JMO and that DMS.

Not sure. It was printed a hunting magazine or archery mag that the shop had where i get my stuff i will find out and my bow is a high country iron mace my buddy is shooting won at 30 in draw and getting 403 fps i seen it on the chrono its crazy that is why i had to have this bow first time i ever bought a new bow but most of that reason is because i got a divorce and do what i want tonow

razor1, man no offense, but come on dude, let's be honest, do you realy think that is smart??

A 60 yard shot is just a "doable" at 260 fps as it is a 386 fps. Either require a rangefinder. Don't leave home without it.

"It seems crazy to me to but as long as they will take care of it if it breaks why not"

I would not want to be around a bow that broke during the shot.....I shoot within my bows limit of more than 340 grains as I am pulling near 70#.

It's one thing to shoot an arrow that light at 70 poundsthat was built with the proper spine like their speed pro arrows.

It is another thing entirely to shoot an arrow spined for 45 pound bows like the Gold Tip 3555. SureHigh Countrywill warranty an Iron Mace down to 3 grains per pound but I doubt that Gold Tip or High Country is going to pay your medical bills when thatGT 3555snaps in half at the shot and goes straight through your wrist.

Don't be stupid man.

"313 fps and switched to the goldtip ultra lite and know i am shoting 386fps"

So you gained approximately 25 yards per second by switching down to a lower grain arrow?> That is a huge friggin difference...warp speed increase.
