Arrow

Looking into gettig new arrows. I currently shoot Easton Axis Camos which are extremely heavy 9.8 gpi 400 spine. Draw weight is 60 lbs. 28" bare shafts. Smarter to stay at 400 or go to 500 spine.

 

I would stay with the .400.

 

I agree with Bruce.

I'd also stay with the same arrow but I'm a fan of heavy arrows, especially at lighter poundages.

 

Agree with everyone else. Don't try to lighten your arrow by going to a weaker spine, it will cause havoc for your setup. If you would like to go lighter switch to the normal axis arrow. I would keep it where your at now IMHO.

 

Click on the Harvest time link below. They are fantastic arrows and at a great price.

 

I have my Harvest Time HT-2 arrows (the "Harvester") at 28" shaft, with 150gr point, 20gr screw in weights, FOB and wraps for a 474gr arrow at 62#. I weighed the arrows+nock+insert+weights and they had a 0.6gr deviation.

 

Victory Archery VAPs. Great carbon fibre arrows.

carbon express all the way

 

If you are hitting what you are aiming at, dont change a thing!

 

If you are hitting what you are aiming at, dont change a thing! Out of curiosity, whay are you thinking about 500s?

 

Can anyone explain to me what the difference between shooting a 400 or 500 would mean? I'm caught up with the GPI and determining the total grains of the arrow, but what does the 400-500 stuff mean and how does it affect performance?

 

Its a measurement of the amount of flex an arrow has. They put the arrow on a device that supports the arrow at two points 26"apart and hang a 2lb weight from it and measure the deflection, unless someone lied to me, that's what I've been told. So the lower the number the stiffer the arrow. Hope that helps.

 

26" and 2lbs is the older AMO standard. Nowadays it is the amount of deflection at 28" apart using a 1.94 lb weight with a 29" shaft.

 

Huh, you learn something new everyday don't you? At least I was close.

 

Great information from both of you. Thanks. I've always wondered.

So the GPI is the method of measuring the total grain of arrow (with the insert, knoc, broadhead, and fletchings) and the 350/500/400 etc. number is the determines the flex/stiffness of the arrow.

 

GPI is just the Grains Per Inch of the bare shaft with nothing else, no nock, fletchings, inserts, etc.

 

Yeah. That's what I meant. I should have been more specific. GPI * length of the arrow in inches + nock, fletchings, insert, broadhead = total grain arrow.
