Help! I'm shooting a right handed 50-55 lb bamboo backed hickory longbow. The shelf is cut in at about 1/4". Brace height is about 6 7/8" and the nock is set at 1/2" above square. I'm shooting Easton Camo Hunters xx75 2315 lite. They are 30" long and tipped with a 140 gr field tip. My draw length is 29". Most of my arrows end up to the left of the bullseye normally in the 4-6 inch range at 15 yards. Groups are pretty decent at 10 yards. At twenty.... even further left. Arrows are mostly in line with center (not too high or low). Arrows are entering the target fairly staight...not angled up or down...left or right.

So the million dollar question is.... do I simply need a lot more practice or are my arrows not making through the paradox and are too stiff? Can I add weight? When they are sitting on the shelf they are pointing to the left which is where they end up at greater distinces. Any advise would be greatly appreciated. Thanks to all.

You're WAY overspined.

Thanks. How do I decrease the spine of my current arrows without adding more weight upfront? I noticed the insert has a hole in it. Can I add a tube or fishing line to increase the overall weight of the arrow thereby decreasing the spine? I've already got 140 gr Magnus broadheads. Do I need to buy different arrows? What do you recommend in aluminum that will allow me to shoot the 140s? These arrows were recommended by someone at the store, so I hope I can exchange them if necessary. Thanks!

There's a pretty good chart at www.arrowsbykelly.com . It goes up to 80@31, and still hasn't gotten to a 2315.

It's been along time since I've shot aluminum, but off the top of my head you might need a 2016, or in that range. Your string, nock fit, release, bow performance, how far off center the shelf is cut, etc. will all make a difference.

This is just a guess, but seems to me the person at the store was just trying to get rid of some shafts that don't sell.

Chad

Yes, I think you are way overspined. The left inpact also confirms that. I think Chad is right in there with 2016. However, you may need to go even weaker.

The closest to you that I'm shooting is a 70", 60#'s at 29" Schulz longbow. I shoot 2016's with that. I also have a Hill Croc that is 58#'s at 29" that I also shoot 2016's with, but they are a tad bit stiff.

You don't. Unfortunately your arrows are way over spined for that bow. You will need a 1916 at 30" with 125 tip. You would have to add another 250+ grains up front for those arrows to fly. Your bow is on the same line as a self bow. Next time you get arrows, spine them 15#'s lighter than the draw weight.

Thank you all for the advise. I appreciate it. Should I go with the xx75 or Legacy arrows? Would 140 gr broadheads cause the 1916s to not have enough spine? I should have come here first. Ugh! Live and learn. Thanks again.

With 140 up front + the 12 grain insert, the 2016's at 30" should work well.

Thanks. I'm having trouble locating 1916s around here. Might have success with the 2016s.
