2) easton hexx 7.2 gpi with reg hp inserts. (23 gr)
269 fps and 54 ft # of ke.
F.O.C. Is 15.39%

3) easton hexx 7.2 gpi with 50 grain brass hp inserts.
260 fps and 55 ft # of ke.
F.O.C. is 19.23%
Total grains is 364.

4) easton hexx 7.2 gpi with 75 grain brass hp inserts

Total grains is 389.

My bow is a pse supershort gx cams. Ibo speed of 330 fps. I shoot 62 pounds and have a 26.5" draw length and shoot a 26" arrow. I use 100 gr heads.

Side note: i previously used easton epics at 8.7 gpi. My ke was 54 at 257 fps. I never had problems with pass thru. The hexx are eastons straitest and most accurate arrow they have ever made. I went from 3" groups to 1" groups at 25 yards. Epics are no longer made.

Now out of the hexx options, which would you use?
 
If it was me....it would be none of the above�overall, to light of an arrow and I don't really like all that weight up front. The best looking choice you have is #1 and #2, but #1 is to light and #2 really is as well, but the spine will probably not be correct on #2�#3 and #4 are out of the question unless you picked a 200 or 250 spine to start with and even then I wouldn't use it. The problem with adding all that weight to the front end to make up for such a light arrow is you are greatly weakening the spine and the balanced trajectory of the arrow in flight.

If you would like, let me play around with some stuff this afternoon on the computer....what year is your PSE?
 
Sorry these spines are 400. And foc is the weight up front. It is what gives you penetration. But too much and the fletching cant stabilize. Thats why carbob express has weight fowards arrows. You say the arrow is too light? Why u say that? The ke is the same a the heavier epic. Keep in mind ke is calculated with speed. Also i have never heard that too much weight on the front weakens the spine? If this is true, then that does change things? I too like option # 2. Also keep in mind shooting a 125 gr head does the same as shooting heavier inserts? Does that mean it will weaken the shaft? I deff will have to research that, thats crucial info.
 
Okay, here is what you have.....you were under spined, if you used the 400's, when you were using the Epics�that ideal spine was .3690. Using the Hex's...your ideal spine .3354, so the 400's are definitely out�even using the standard lightweight insert you will be slightly under-spined. Your best combo if you were going to use the Hex's is to go with the Hex 330 and use the 50gr insert and a 100 grain head and that will give you almost a perfect spine match with an FOC of around 16.6%. Without the 50gr insert you will be slightly over-spined, but adding that weight will weaken the spine and bring you into a perfect match. However, standard Blazers may not have enough to stabilize the arrow with the weight up front....in that case you may have to go to a 3-4" vane, which will scrub off some speed�you'll just have to play around with that. Below are the "techie" measurements..

ST Epic 400 .3690 spine match
54ke/257fps/355gr-out of the bow
48ke/247.5fps@30 yds
-5.98" drop from 20 to 30 yards

Hex 400 .3354 spine match
53ke/255fps/364gr-out of the bow
48ke/245fps@30 yds
-6.09" drop from 20 to 30yds

Hex 330 .3354 spine match
53ke/250fps/380gr-out of the bow
50ke/241fps@30yds
-6.47" drop from 20 to 30yds
 
See i wanted to go with the 330's but easton said the 400 bc the drawlength weight and cam. Dang! Great info there! Also are the above stats calculated using 50 grain inserts?
 
Also, if i go with the 330s do i have to add 50 grain weight? Or can i use the reg 23 grain insert? What will that do? Still need 3" vane? Thanks for the help btw! Too bad i bought a dozen of 400 already with blazer
 
I believe im going to order another dozen in the 330 with 3" vanes and use 50 grain brass insert. I believe that will be perfect. Thats what u came up with and i recalculated and thats the only way i can get my foc up without weakening the spine. Would you agree out of all the options i listed, number 1 was the best choice?
 
My numbers will be slightly different from what you have, because I do not have you and the bow here to take specific measurements....I am estimating only slightly.

You are going to be weakening the spine if you add weight up front, but that is okay because you are over-spined to start with by using a stiffer spine arrow like the 330. By adding that weight via the insert you weaken the spine enough for almost a perfect spine match. Remember, added weight up front weakens the spine....weight taken away from the front or added to the back stiffens.

Of the one's you listed, #1 is the best choice, although you are still on the side of being under-spined. I am not a fan of such light arrow weights, but with short draw lengths it is a little harder to get the proper mixture of k/e and drop/speed.
 
Watch out for what you might hear on this topic on Archery Talk. Guys over there swear a person needs tons of FOC when 11% is perfectly fine.

I recommend a fixed blade head like Magnus or a solid smaller cut mechanical like Ulmer Edge or Grim Reaper 1 3/8".
 
I just upped the FOC on my CE Reds today just to play as I am going on an elk hunt the first week of september. I will be completely honest by saying that I was amazed at how much better my arrows grouped out to 70 yards. I shoot an Insanity at 70 lbs with a 125 grain head. I added 25 grains to the front and my groups shrank significantly. I shot 4 groups at 70 yards with the biggest group being 5 inches. That is good for me as I generally shoot inch per ten yards. I will be keeping this setup for the elk trip as of right now. Play with FOC and see what you think. I do believe that those arrows are a little light, but for deer thay will be fine. I have killed a pile with my 380 grain blue streaks, but have never got the groups at the range that tight. Try high FOC and see if you like it. I shot better and got better penetration, so for me It was a win win.
 
I like the Carbon Express Mayhem 350, not the hunter. I have used them for several years with both feathers and blazer vanes, with 3 different bows from 72lbs down to my new one at 66lbs. They fly tru and drive deep. Every deer, except the one I spine hit, were complete blow thrus. Even went thru one and hit a rock the size of a beach ball destroying my Muzzy and the nock was blown out. Put a new insert in and nock on it a shot it till I lost it.
