Help design an arrow.

OK what's the ideal FOC?

[demontang]

For broad heads 13-15% has worked the best form what I've seen.

OK so say I want a 27in carbon 9.3gpi 340 spine with 100gr savora broadhead. Straight vaned. Non wrapped 3 3" fletchings. Standard nocks.  Would I meet the 13-15%FOC and be legal?

You would weight legal at 402.2 grains using easton cb inserts and diamonds vanes as reference foc would be 11.33% you need about 25 grains more up front and you'll hit 13.33% cb inserts weigh 21 grains.

I came up with a 393 grn arrow using blazers. Foc is still to low. If you run gold tip 340 hunters plus the fact insert weight you'll hit 14%

[Jolten]

Are inserts available at different weights?

[demontang]

You can find brass inserts and goldtip makes weights that screw in the back of inserts to adjust foc.

I can plug all your stuff into my calculator, but I need to know basically everything you can tell me about your setup. I've got your bow weight, draw length, and poundage. Need the weight of stuff on the strings (peep, silencers, d-loop, etc. If you don't know, just guess 20 grains), point weight, if you're using wraps or not, if so the weight of those, then which arrows, inserts, and nocks you're using.

Just guessing at a standard point weight of 100gr, insert weight of around 15gr, nock of around 9gr, and 3 blazers with no wraps, 20 grains on your strings, and a 28" arrow, you'd need to be around .430 for spine. Which you shouldn't have any trouble hitting with a TON of arrows on the market.

I'm a 27" draw and run Easton Bloodline 400 spine cut to 27".  I use standard insert and 125 grain broad heads.  Total weight is 413 grains with a 14% foc.  They fly well, but the spine is on the top end for the draw weight at 67 lbs.  My broad heads hit with my field points though, so i'm not worried.  I've put a lot of miles on them this year and only broken 1 when i hit my garage.  Didn't even break one when i hit a 1x4 and blew through it with a broad head.

Anymore suggestions? Xmas is coming hehe

What do you mean by "Straight vaned"?

[Jolten]

Non offset / helical set (really hope I used the right terms) so they run straight edge from nock to point. | vs / if that makes sense.

Why exactly do you not want helical?

[Jolten]

I've heard if your using a capture style rest it can cause issues, and trying to keep it as simple as possible. I'm a big noobie when it comes to all this arrow stuff.
