Summary of arrow modification experiment

[NorthernRaider]

Summarised version of arrow project

OK I've made 5 arrows out of the glass fibre cheapo target arrows, I cut off the point of the target head but left the chrome body of it still in place IE I only cut off the pointy bit not the whole target head.

I then ran an 8 mm drill bit inside the 5/16 parallel field heads about 12 mm to remove the threading.

I lightly sanded the remaining target arrow head to provide a course surface for the epoxy.

I then mixed a small amount of Araldite rapid and coated the roughed up surface then slip on the drilled out field target heads, I ensured they were flush fitted and temporarily secured them in place to allow the epoxy to set.

Bingo A very sharp, very pointy steel field head attached to a budget arrow.
I'll try em out later and let you know how they perform from the Banshee.

My finding are thus, the modified arrow has much greater penetration than the original training arrow by about 50%, But it’s not as accurate I can get 4 to 5 inch groups with the training arrow as bought but I'm getting up to 8 or 9 inch groups with the modified arrows.
Still good enough for PA security duty though !!!

However I also tried using my arrows from my recurve bow which are Easton Blues XX75 alloy1816 arrows, these come with heavier alloy target points which are nicely sharp, that are inserted into the arrow shaft rather than slid over, and these worked superbly. They appear faster and more accurate because they are lighter and more streamlined. The Blues penetration was superior to the training arrows but slightly inferior ( not by much) to the modified arrows, but much more accurate.

Weight wise the Eastons are 23 grams
Petron Fibreglass are 33 grams
and the modified arrows are 36 grams

So the readymade middle price arrows appear to offer the best all round package of speed, quality, accuracy and penetration.
The nearest I can find readily available are these 1820 Blues
