Heavy arrow build thread

[Bowmanmike]

I shoot the cheap sportsman's guide trophy hunter made by victory. They only offer 350 and 400 spine. I'm up to 660gr with the 350. Obviously arrow spine will differ between manufactures. I don't think I could go much heavier with these arrows. I will be ordering the Sirius 200-250 test kit to try. 29inch arrow and 60pd draw.

Hope that works for you. I shoot a 300 spine arrow weighing in around 580 with a 29.5" DL and 60# DW.

They shoot good

Done with my winter league and now its time to get serious about setting up my new shafts. Prime Black 1, 65#, 30" draw setting. Shafts are GT Hunter XT Xtra- 29.5", 100 grain brass insert, 150 tip- 300 spine. Have been trying to get rid of a 1.5" right tear (bare shaft) and for the life of me- can't correct it. Shooting from 6' to paper- and then 25' just to watch flight. Arrows are angled into target tail right pretty hard. Rest adjustments don't affect it much, so I returned it to center. Can't believe I'm over spined, but may need to track down a 200 grain tip just to verify that. Really want to get it dialed in before my turkey season starts at the end of the month.

 

[Bowmanmike]

I doubt you are overspined with that set up. Tail right is the same condition i had and it was due to my DL being set to short and me torquing the grip. Now that all that has been corrected i am shooting my best groups ever out to 50 yds.

No problem, just passing along info. 200 seems awful stiff, even with 300+ up front but I will get a 3 pack of Apollo 200s and see how they tune. If they do I will be able to take my current broad heads and build 735gr arrow, with 21.2% FOC, that would be maxed out specs if it tunes with the full insert weights from Ethics.

I'm not trying to say you most definitely need a 200 spine, just relaying what I was told. Anyone else care to chime in on the 200 spine thing?

If you’re shooting over 70 pounds and have a longer draw length/arrow then a 200 spine could become necessary if you’re adding enough weight up front. A friend of mine shoots a 75lb Mathews VXR at 31”. He’s not interested in building an EFOC arrow but would not be able to anyway with his current .260 spined shafts.

Like it was mentioned above, spine numbers should be a starting point. They dont account for EFOC, how aggressive your cams are, or your concern for impact paradox.

I would venture to say different species have different degrees of “hardness” and produce more or less impact paradox even without hitting bone.

Paper tuning at multiple distances really shows a lot for what spine your bow prefers if you can keep your torque consistent.

I mentioned earlier that I was recommended a 200 spine by a professional but my gut tells me it’s to stiff. OT2Go says it is to, way stiff actually. I’m getting bullets holes with 333gr total up front with Rampage 250.....

After seeing some of the concerns/posts of some folks about 250's being to weak for the type of weight that I have upfront (380gr) I revisited the Victory site and used their spine calculator to look at mine again, and no matter how I input the required fields it says 250 is the right spine for my build. I got great flight but the safety concern of using an under spined arrow, ( I've seen some of those videos) I wanted to make sure I wasn't gonna be surprised at 20 feet.

I don't know about safety concerns, I believe I could whip a deer to death with my BE Carnivore 250s

Got my arrows complete for the year. Black Eagle 250 29" with 4 vanetec vanes, 100 grain brass insert, and 150 on the tip. All white for hunting and all read for practice. Weight is 587 grains 17.9% FOC and all are withing 2 grains of each other. Super happy with how they came out. The longer arrows with no wrap are 6 fletch and 32" for my Excutioner Necker guillotine for turkeys.

Update: after flinging a bunch of arrows I decided I needed to remove some weight. I dropped down to a 100 grain broadhead so total weight now is 537 at 15.5% FOC. Bareshaft, broadhead, and field point seem pretty dialed at 30 yards. At 40 yards I stack 2 arrows with broadheads a bareshaft and 2 fletch inside the black dot also. I wanted to be closer to 600 grains but my bow is tell it wants the shafts stiffer and lighter. Not going to argue with results. Becuase of the lighter arrow I picked up 10 FPS. It's now shooting at 279 FPS.

KE = 92.8
Momentum = 0.665 slugs
What could stop that?!

Hahaha. Right. It absolutely pounds.

A friend has a BT Reign 6 that shoots those speeds, it makes heavy seem light.

300 spine gold tip hunter 9.3 grain at 28.5 inches
100 grain inserts
125 points but undecided on broadheads
Blazers and lighted nock
EST. Low 500s?
Didn’t bare shaft tune but making palm size groups at 30 out of a VXR 28 with 28 inch draw and high 60s poundage

I have a similar set up and i think you are closer to 550 or 575. Gold tip has a decent calculator,or victory archery...

I bought Cutthroat 125s (single bevel, tanto tip). Built like a tank. Mine grazed a concrete embankment the first time I was shooting them. Still putting the sharp on it after that, but I’m close to having it back to hunting sharp. Watched some videos comparing it to Grizzlystik broadheads and others - pretty impressive. Also has a great warranty.

 

[Hogwild2004]

And btw, it left more of a mark on the concrete than the other way around. Pricey, but worth it in my book.

Thanks for the input! I have been looking at those, vpa two blade and the black hornets...how hard is it to sharpen a single bevel? I’m proficient keeping field and butchering knives hair popping but never dabble in a single bevel

Same as a double bevel....just half the work
