More arrow questions.

[Seahawk12]

I've been considering making a switch to a heavier arrow.
I'm leaning towards 500-525 total grains.
So a 125 grain BH, the 35(+-) grain for inserts fletches etc, and the shaft.
I have two bows that I shoot. One is set at 65#s and the other is set at 70#.
Both have around 29.5" draw length.
So, which spine would be best? The 300 or the 340? Those seem to be the easiest to get.
Any suggestions on arrows? Are the full metal jackets better than carbon? Or is that just come down to opinion?
Thanks for any information.

the .300 will be a better option. It is always better to have a stiffer arrow than a weak arrow. to reach 500gr you will likely need to add weight at the insert with most arrows.  there are a ton of arrow options that feature an outsert, Easton HIT insert system, or the goldtip FACT weight system, that can be used to tune the tip weight of your arrows.

A ton of people have great luck with the FMJ arrows and like them because they are heavy. I like a heavy arrow, but I think it matters where the weight is in the arrow. I prefer an arrow with higher tip weight and lighter weight over the shaft. This increases a measurement known as FOC or front of center, which refers essentially to the location of the balance point of an arrow.

Think of it like paper airplanes when we were kids, to make them fly straighter and farther you would add paper clips to the nose right? the same is true of carbon arrows in my opinion.

The limiting factor here is the spine of the arrow. The more tip weight you add, the weaker the spine of the arrow. Depending on the IBO speed of your bow this could be problematic.

If I was you, I would first go to a shop and find out how short you can cut your arrows and shoot them comfortably. I prefer the end of my arrow to be past the shelf so that broadheads don't cut my fingers at full draw/release. Shooting the shortest arrow you can will help stiffen the arrow and allow you to add more tip weight.

Although I don't shoot them any more, the goldtip FACT weight system allows you to add and remove weights from arrows and experiment to find out what weight combination is right for you. It wouldn't hurt to order a half dozen and do some experimenting. once you figure out what spine/tip weight combination is right for your bow, you can branch out to other brands and find similar setups.

Good luck

Sneaky is spot on with his advise.  I believe that the cam system on your bow will make a difference in what spine arrow you may want to shoot.  If you have an aggressive cam system them you may want to go with a 300 spine arrow you may be able to get away with an Easton 330 spin arrow.

I am shooting an Easton 330 Hexx arrow cut 29" carbon to carbon with a 50 grain brass insert and 125 grain tip I use three AAE Stealth vanes with a wrap and my arrow weight is 455 grains. This arrow gives me good front of center and flies great out out of my bow a Hoyt Carbon Syder Turbo 29.5" draw at 62 pounds. The speed I am getting is not blazing fast 282 FPS but it will work for me.

I have killed around 15 to 18 elk (No Wall Hanger Elk) with arrow weights from 400 grains to 455 grains,  I really don't see the need to shoot an arrow over 500 grains.  With that said if I could shoot a 500 grain arrow at 285 + FPS that would be epic

You'll want a 300 spine. I use the Gold tip weight system to get the total weight up. Im running element arrows with 50grn fact weight and 100 grain RAD head. Im at 518grn total.

Good information.
Thank you all for your input.
BTW, while researching more tonight I googled a couple of things and google tried to figure out my line of thought. They were a little bit off. Heres a screen shot.

Which element arrow are you using?

I'm shooting Black Eagle Deep Impacts 300 spine with the stainless outcerts, 125 grain head, and lighted nocks out of a 70 lb bow..  525 grain total weight... fly good and hit hard...
