so i bought some of the 31" allen 45-70# spined arrows at my walmart and tuned them to my 84# hornes archery bow but i have no idea what the GPI of these arrows are, does anyone know? even with a 8gpi weight tube inside they still chrono out of my bow at 193 fps on average and that seems like maybe the shafts are too light the set up is
trimmed to 27.75 with a 1.25" footing up front and a .75" footing on nock end
125 grain fieldpoint and i use a 2 fletch of feathers shooting off the shelf
Pull the nock and point. Remove weight tube and weigh them. Take off around 15 gr for insert and divide by the length. That should get you a pretty close weight.
Not 100% sure on weight but if i remember right the are around 8.5tp 9 gpi. They are really close to the same weigt as a victory vforce 350. A buddy of mine bought some for his compound ajd they group right with his victories which are 8.8 gpi out to 40 yards. Not a bad arrow for only 3 bucks apiece
Just adding weight tubes or cord will not change the effective spine it will only make the arrow heavier.
Your going to have to decrease point weight , shorten arrow or add more/longer fletching to make them stiffer
I had read those arrows tended to have week nocks and others reported the carbon would split either at the tip or nock.
I bought one, 55-75 was as light as I could find, and tried getting it to bare shaft at full length. It was a bit stiff out of my BB ILF warf with 55# limbs with 100gr insert and 125 gr tip. I also noticed the nock broke within just a few shots and when i went to remove the nock I saw a very fine split in the shaft.
I really hoped to use them but I am steering away from them now.
I wish I could find a boatload of those shafts to sort through and weigh. They bareshaft and fly like darts out of both my Omega R/D longbow and my Warf. The problems I had were: nocks had to be re-glued and weights were pretty inconsistent, sometimes as much as 10 grains per shaft. Otherwise I've hit the same boards with those that I hit with my CE Heritage 250s. Dug them out in both cases, checked for cracks, and kept on shooting. As soon as they start stocking them again I'm going in with my digital scales and buying every one they have that hits within 3-4 grains of my target weight.
Fine for knocking around the backyard. I chop 'em down with a metal cutoff blade on my miter saw ($5) after wrapping the cutoff point w/masking tape then fletch them w/feathers and they are way better than cheapo wood/fiberglass arrows for my son and his buddies. I've shot them out of my bows up to 45# and they are just as accurate as my $$$ arrows at distances less than 40 yards. Perfect backyard arrows for newbies, guests and knocking around. Even w/feathers and inserts we are still talking a decent carbon arrow for $4, less if you get them on clearance.
Jeesh- I hadn't noticed the date. A buddy was asking how I could afford 2 dozen carbon arrows and let kids use them so it made me look up the topic on the forum. Here in the NE they'll probably go on clearance the end of this month when the season ends.
