Heavy tip or insert

[bolo7735]

I currently shoot GT5755 400 spine. I use 220 grain field point. Does it make a difference in arrow flight if I use a 100 grain insert with 125gr point  compare to 220 grain point?

[TxAg]

I use a 75 grain insert with an aluminum footing of 20 grains....the rest is made up of a 125-165 grain broadhead depending on a few factors.

In short, I don't think it makes any difference.

[Knawbone]

I would think very little-if any, but I'm not a carbon shooter.

It should not make that much of a difference but the only way to know for sure is to build one up and try it yourself. I shoot 55/75's with a 100gr insert and 150gr points out of my 50# at my DL Sarrels Blueridge longbow.

I can't tell. A shooting machine might be able to show the very slight variation in spine, but I doubt there's a human alive that could honestly detect the difference.

Flight, not much difference. The 100 grain insert will make for a sturdier arrow. That 220 grain point in the flimsy aluminum insert that comes with the carbon arrows will not take alot of impact before splintering the the end of the arrow. The 100 grain brass inserts are MUCH tougher. On one set of arrows I am shooting I have a 250 grain point, plus the 100 grain brass insert. A few weeks ago while stumpin I mistook football sized, moss covered piece of quartz for a moss covered piece of wood. Sparks flew when the arrow hit. It was a horrible sounding impact, much like nails on a chalkboard but the arrow was none the worse for wear. I was amazed it took that hit without damage!

BowHunterGA X2 on the toughness factor

I use the 100 brass plus 125 points and they have never failed at the insert.  Can't say the same with the aluminums.

Yes, it absolutely will.  I was surprised by how much.  I've been tinkering with the point to insert distribution on my full metal jackets and bemans and the more weight I distribute to the point vs the insert the larger the impact it has on dynamic spine.  Total weight up front stays the same, distribution between the two is all I'm changing.  I think the fact that they are the HIT inserts makes the impact more dramatic but I think it would the distribution would still have an effect on any carbon set-up.

I changed from 100 grn brass insert to 50 and increased point weight from 175 to 225 and the dynamic spine changed pretty considerably - weakened the arrow.

I'd put the arrows together the way you want to shoot them based on what type and weight of broadhead you want to use.  Use a heat reversible adhesive with a low temp reverse (only heat the point and not the shaft), bareshaft starting with full length and cut accordingly.

Also, as others have said, use a brass insert.  The aluminums are weak and have a higher tendency to fail on bone.

It will change your FOC, so its a trade off. Weather u want a tougher arrow or higher FOC

My experience is that it shouldn't make a difference.

[Steelhead]

The 100 grain brass inserts are longer than aluminum inserts.That may stiffen the arrow spine a bit as far as the arrow not bending as much.Because the longer insert part up in  the shaft is not gonna flex.Its gonna act like a slightly shorter arrow.

[Friend]

Should increase the arrow spine ~3#'s.

I'd work it by choosing the broadhead and adapter first and then work backwards for the insert weight to arrive close to what you want.
