Broad head adapters?

[ranger 3]

How would you put the weight of a screw in Broad head adapter in the spine calculator? Would you put under insert or tip weight?

Thanks

I would say "tip weight" because the mass is centered there.  Just combine it with the broadhead weight.

point weight.. I have some 202grn BH's. Snuffer 160grn + 42grn adapter. After making what You want for screw-in's just weigh them and enter that weight in the box.
