Arrow Question

[Chouse12]

Hello,

I recently purchased new arrows. I miscalculated what size I truly needed. I should have gotten 500's and when I bought 300's. What would the main set backs be and is this a big mistake?

[dpg481]

Are you shooting them out of a 3d rig or something?

[Roy D Mercer]

I assume the 300's are weaker than the 500's?? If I remember correctly the weaker arrow will group to the right of the stiffer arrow. You will not know until you shoot them.

You can always reduce poundage if needed........

If you are referring to the spine being .300 vs. .500, the .300's are the stiffer shaft. You probably will not notice any huge difference other than .300's are typically a little heavier.

What are you shooting them out of? Compound, Recurve? Whats your Draw and poundage?

Post up your bow DL and DW. That's a pretty stiff spine.

...smaller the number the stiffer the arra... generally. I shoot 300's in the Axis N-Fused shafts, but I have a 31 1/2" draw so shoot them full length at 70+ pounds...

The heaver broadhead you shoot, the stiffer shaft you need to put behind it. If you're shooting a trued/tuned center shot compound with a drop away rest, they should shoot just fine for you... probably give you better penetration than whatever you were shooting before. Likely have to readjust you sights for the heavier shafts...

I have an older model Mission. I am pulling around 57-60lbs. I have a whisker biscuit rest. I actually had to purchase new arrows after a pig hunt in Richland Springs TX! I did notice they are deffintely stiffer. Judging by the graph on the arrows, I should have purchased the .500 instead of the .300 because of my 27" draw. I just got done shooting and did not have to adjust my pin at 20 yards but my 30 yards seemed a little more sloppy.

I am shooting Rage 2 Blades-

Thank you everyone for the help!

What is the reason for different stiffness in shafts? Does it help with distance and or penetration?

I have a 27" draw and pulling about 57-60 lbs. Primarily Whitetail and Turkeys

The original reason goes back to traditional bows. There is something called archer's paradox that allow for the arrow to flex around the riser of a traditional bow. Too stiff and it would kick out from the riser and not come back or recover enough. Same thing with early compounds that shot up against the riser with plungers and such. Now with modern compounds and specifically drop away rests spine isn't as crucial. Most bows, and particularly with fixed blade broadheads, with shoot better with slightly over spined arrows. Less flex in the arrow and less oscillation coming out of the bow leads to more stable flight. Drawbacks to stiffer spine is usually more arrow weight. And, spine has to do with the amount of deflection or bend in an arrow when weight is hung from its center. Basically a measure of how flexible it is. I would see how you do with the 300 spines but you are quite a bit overspined. Like a 400 spine with fixed blades would probably work. The mechanical broadhead overall will be more forgiving with incorrect spine(like a field point). Hope that makes sense and helps.

Good explanation doc.

So all that education was good for more than delivering babies.

Great post Doc.

That and I spend way to much time thinking about archery!
