How does this look ?

Shot from 15 yards from bear hunter 56lb @28

NICE  

where are your fletched arrows going? I was always thought that you bare shaft test against fletched arrows to know what the arrows are doing. at least we know your nock point is good.

compared to a fletched arrow:

BARE SHAFTS GROUPING LEFT

Reason: Over spined (stiff)

Remedy: Heavier point, or thinner side plate, or longer shaft, or switching from a Dacron string to a DF-97 or Fast Flight, or weaker arrows.


BARE SHAFTS GROUPING RIGHT

Reason: Under spined (weak)

Remedy: Lighter point. or thicker side plate, or shorter shaft, or switch from a DF-97 or FF string to Dacron, or stiffer arrows.

They hit in the same place . This are the heavy hunter 500 with 145 tip . Weight in at 620 gr

great!!  lets see it  

Go fletch!      

Yep if they are hitting that straight and grouping with your fletched arrows than you are definately in tune.
