RE: Hey Newman1...check this out!
First priority was a 300-spine arrow. Then came the matching total weight of arrow to my game of choice. Blacktail deer are lighter in weight as compared to whitetails, so a heavy (440 grain plus) arrow is not required with my bow to get a pass through. Furthermore, a lighter arrow will help my trajectory and range estimation some. Some states near me (Idaho) have a 400-grain minimum arrow weight for hunters, so I took that into consideration. I talked to Tim G at GT and this is what he recommended for my specs. He hunts with the GT UL 300 spine arrows and has had no complaints. He also talked me into a 3 degree off-set 3-inch low profile (.380) VaneTec vane vs. my 4-inch high profile (.480) VaneTec Vanes. Should give me better clearance from rest and increase my FOC just enough to counteract the weight of my white arrow wraps. Good vane size match for mechanicals. I’m going to start building them myself with all flo green fletching. Tim gave me some great tips on arrow building. He builds arrows like I reload for my long-range rifle. Arrow building tools are on the way. Total arrow weight should be right at 409 grains with a speed of 295 fps. Puts me at 5.8 grains per pound of draw weight with an estimates 7.5-8% FOC. If my accuracy gets worse with 295 fps, then I’ll have to make some changes. I almost ordered the A/C/C 300 spine arrows, but decided to try these out first.
So did you comply with your concrete wall test yet?
