Very interesting information! I well be experimenting with the information you provided.

The drama continues. I tested all the combinations I posted earlier that shot bullet holes without any bow tuning. Here are the results with the Hooter Shooter at range, all groups are 5 arrows, groups measured from center to center (like you would in a rifle competition.) Weather: Clear 32 to 55 degrees F. (Took the better part of the day) Wind: none to speak of. Elevation: 4300’

Matrix (27.5”, 100g tip)
20yd- great grouping had to remove each arrow before I shot another.
30yd- groups began to open up. Shot 1.5” group
40yd- groups 1” smaller than 30yd. to me indicates a spine problem.

ACC (27.75”, 125g tip)
20yd- great grouping had to remove each arrow before I shot another.
30yd- groups <0.5” still very tight. Removed arrows before next shot because they were shooting so good
40yd- groups <1” still very tight.
Over all this was the best grouping setup out of the bunch. Speed 280fps

ICS400 (29”, 100g and 125g)
20yd- great grouping had to remove each arrow before I shot another.
30yd- groups <1” still tight good flight
40yd- groups 1.25” still good results. I would defiantly consider this setup for hunting, or general shooting purposes. Defiantly a less expensive alternative to the ACC shafts. Tip weights really didn’t affect the accuracy. 125g was a tiny bit tighter than 100g tip at 40yd.

GT5575 (29”, 100g and 125g)
20yd- great grouping had to remove each arrow before I shot another.
30yd- groups <1” still tight good flight
40yd- groups 1.25” still good results. I would defiantly consider this setup for hunting, or general shooting purposes. Defiantly a less expensive alternative to the ACC shafts. Near identical results as ICS400’s. The only difference is these shafts liked the 100g tips slightly better than the 125g tip.

ICS340 (29”, 125g tip)
20yd- great grouping had to remove each arrow before I shot another.
30yd- groups 1” still tight good flight
40yd- groups 1.375” still good results. I would defiantly consider this setup for hunting, or general shooting purposes. These shafts seemed a little stiff, don’t know why they should spine pretty good in my setup. Slightly better results with 125g tip than 100g so I posted them..
2314 (28” 100g)
20yd- great grouping had to remove each arrow before I shot another.
30yd- groups <1” still tight good flight
40yd- groups 1.375” still good results. These shot great! A close second to the ACC shaft much less money.

I did test several other arrow configurations that didn’t shoot quite as good. The 2314 is the only shaft that didn’t shoot a perfect hole from the gate, but shot great at all ranges. I did shoot all arrows myself to confer results. I found the ACC, ICS400, and 2314 shafts gave me the best groups.

What I still don’t get is the ACC shaft that should be way underspined for my setup shot the best in both the Hooter and in my hand. I have some more of those shafts cut to that spec to play with. According to every chart and my gut I think the 3-49 would be a better match. When I get a hold of some I will test them and post the results. As it looks now though I will shoot the 3-39’s

On a side note. We entered bow information into Archers Advantage about my bow by taking direct measurements (which are slightly different than factory specs). After all the input the program spit out the ACC setup as optimum. INTERESTING!!!

What do you all think?
