I know I should try and see what works best for my set-up but up here in Canada arrows are expensive and the shops only sell in 6packs.

Shooting a CS30, #60, 28" DL, arrow shaft is 27" carbon to carbon. 100g head, 20g nock, 18g in vanes. Currently shooting Victory VAP 400s with the 35grn aluminum outserts. If I switch to the 95grn SS insert will I be under-spined? If someone can run it for me, thanks!

I looked up the Victory arrow chart and you could go to 350 spine , always better to go stiffer or so I've read here on AT. I'm in the same boat as you living in Canada but in saying that Lancaster Archery is my go to shopping site. Even after exchange,duty and shipping the price is not that bad plus you get what you need and want. Pro shops around me suck and are 3 hours away.

I would buy 350's if you are going to be experimenting with weight up front. Adding 60gr up front is significant, and not sure I would shoot 400's that way, however Im sure you could shoot the 35 or 95gr inserts with the 350's.

I have mocked up a couple arrow choices mixing between the 35grn aluminium and 95grn SS outserts as well as switching to a 125 grn point. Also going to the TKOs which are a bit heavier gpi, is an option.


Gamer 400 + 125g point = 390g @ 14.3% FOC (under-spined?)
Gamer 400 + SS Outsert = 425g @ 16.6% (under-spined?)
Gamer 350 + 125g point = 410g @ 13.6%
Gamer 350 + SS Outsert = 445g @ 15.9%
TKO 400 + 125g point = 425g @ 13.0 % (under-spined?)
TKO 350 + 125g point = 435g @ 12.7%


With my lower poundage and shorter draw still want to keep speed up, but need heavier than my current 365g for elk/moose hunting.

The Gold tip arrow selection chart has 3 point weights, 100, 125, and 150 grains if you study it you can see how increasing point weight weakens the dynamic spine of an arrow. You can figure about 3-4 pounds reduction for every 25 grains increase in point weight. If you go with 195 total point weight according to the gold tip chart, 400 is borderline with a 150 point and the extra 50 grains would be like shooting 66-68 pounds and they recommend 340 for the 195 weight at 27/60.
I am shooting a 55 pound 29" shaft with 125g point and 60 grain insert and I had to go to 300 spine to get them to fly perfectly! And that is exactly what the GT chart recommends if I add 4 pounds for the extra 30 grains of weight up front.

Good idea thanks.
