Im just wondering how many guys actually take the time to sit down and figure out how many grains per inch they are shooting and total arrow weight. Most guys throw on 100 grain broadheads on X arrow because thats all they know.

If some guys took the time to calculate what they are shooting in arrow grains they would realize that theyre shooting an arrow that is enough for africa big game. when it boils down to a head weight choice, vanes, knocks and actual arrow shaft some situations you can shoot an arrow which appears identical but is over weight by much more than necessary.

Not all arrow shafts are created equal, dont just throw a 100 grain head on your arrow cause your buddy did. Figure out what you NEED with a correct spine. All the time we hear SPEED SPEED SPEED, KE KE KE... well... you can see massive gains in speed by controlling how much arrow you sling.

I myself was guilty of this until i started building my own arrows.

I can show you two arrows, one which will kill a buffalo and produce about 250fps and one which is more than enough for a whitetail shoot 280fps by a change in head size/vanes/arrow shaft.

Watch your weight!

I shoot a 350 gr. arrow at 311 fps at about 70 ke to gain another 5 lbs of ke a would have to drop my arrow speed to 200 fps with a 650 gr. arrow. The only way a gain any big gain in ke is to up your poundage

Kinda what I was saying, it was more along the lines of you can gain speed without a huge loss in KE. Most manufactures of arrows make similar diameter arrows or similar size cut shafts which vary in weight grately.

A carbon express maxima shaft is about 7.4 gpi while their economy arrow the terminator is coming in about 9.9 gpi... 2.5 gpi makes a big difference when multiplied by 28-30+ . Most broadheads are around a 1 to 1.5" cut for 100 grains while an 85 is usually the same size.

No one ever tries to solve speed problems with correcting the arrows. Its always run out and buy a faster bow. You might have a fast bow and could be really throwing it in the gutter.

You can get away with prob shooting about any combo you want out of your bow. Most guys cant.

I shoot Gold Tip 22 series. I get 7.3 gr./inch, use a 100 grain tip, with blazers and wrap. My arrows weigh in at 375-378. I get 275 out of my Hoyt AM32 at 63 pounds and 27.5 draw.

I used The Archery Program to design my arrows. I've got the older original Easton Epics cut down for my 26 3/4" draw with 85gr Slick Tricks. I believe they come in at about 352gr. with wraps and blazers. Shot out of my LX at 64 lbs., they have are heavy enough to be quiet and efficient but fast enough to forgive range errors. TAP is a great way to learn about arrow selection and design by changing shaft length and point weight for a certain spined shaft to see how the calculated dynamic spine changes. Although I don't change arrows often it takes a lot of the guesswork out and prevents buying the wrong shafts and broadhead weights.

Re: Why do you shoot what arrows/broadheads you do

Gold Tip XT hunter 55/75(8.2 gpi-bare shaft weight is 230 grains) with 100 grain rocket steelheads, blazers, and 4" arrow wraps. Total weight is 385 grains. Shooting 328 fps from my pse xforce gx 7 @ 70# and 29.5". Creates 92 ft lbs of KE, and it still heavy enough to be very quiet coming out of the bow. I am moving to steelhead XLs, to have a little larger cutting diameter. I certainly have enough energy for any animal on this continent.

Re: Why do you shoot what arrows/broadheads you do

I shoot 11.4 grains per pound out of my 46 lb longbow. It probably chugs along at 170 fps give or take. I wouldn't want to be hit with it. I shoot this combo because it's what I prefer. A well placed shot in the chest cavity makes for a dead critter. Dead is dead no matter how you slice it, No pun intended.

I also shoot over 10 grains per lb out of my 57 lb recurve. I shoot about a 580 grain arrow, at about 200 fps. A nice magnus stinger 2 blade on the front makes for great penetration.

my setup is a easton fmr in 400"s at 29 inch's with 100 grain g5's at around 11.5 grains per inch. perfer a heavier arrow for more peneration over a light setup and more speed

Re: Why do you shoot what arrows/broadheads you do

I'm shooting Easton Full Metal Jacket 340's cut at 28.5'' with a 125 grain Magnus Snuffer or 2 blade Stinger on the front. With lighted nocks and wraps and 4'' duravanes I am around 518 grains or so. These fly wonderful out of my Elite GT500 set at 70lb.

Re: Why do you shoot what arrows/broadheads you do

I guess I'm one of the few people that still use aluminum arrows... and big one's at that...30 inch XX75 in 2315 535-538gr. with 100grain 3 blade undertaker broadhead, with lumenok... I'm getting over/around 100FPE with my 65 lb. bowtech general... but speed doesn't matter to me... why shoot a bow that is shooting 350-360FPS if you can't hit squat with it? All that matters when it comes down to it is good shotplacement
