I'm working on a arrow build and need a spine calculator for heavy inserts and broadheads. It will need to calculate 400-500 insert head combination. Thanks

Don’t put all your confidence in that spine calculator. Spine charts and calculators are just a rough starting point.

One thing to consider. If you are going to be shooting arrows much over 28" from a bow that has any reasonable amount of cut to center, in a bow over 50'ish pounds you may have a hard time finding anything.

Why in the world would you need 400-500 grains wt. head/insert, you will be shooting an arrow that weighs 8-9 hundred grains.

Bob I shoot heavy arrows for the penetration. I keep my shots close and tight groups. Its works for me.
