Anybody have experience with that? What is there that would work best? I plan to load the front with 300-400 grains. I got my eye on some heavy trad bows, maybe after Christmas I will get into that. But I figured I would ask here about tuning the arrows.

I made arrows for hunters going to Africa to use on Cape buffalo and other dangerous game. A 2219 filled with a uniform sized sand that we purchased specifically for this purpose was the most popular choice. Tuning with paper is the best way and then physical weight for the type of game.

Tuned by point weight?

Nock height, brace height arrow length, point weight, pretty much everything goes into paper tuning. They won’t ever shoot a bullet hole through because you’re using a tab/glove.

I have had pretty good luck playing with nock point and trimming the shaft. Once i got a bare shaft sticking out straight, seems like I can go up or down a little in point weight and my broadheads still fly.

Also seems like a little weak or a little nock high/left is more forgiving. But I am shooting a bow cut to center, so it takes a stiffer shaft to tune to begin with.

Does the sand stiffen the spine?
