aluminum spine?

[Mryan2176]

Im buying arrows for my 50 pound longbow. The bow is a don don stik and its cut to center with Velcro as a side plate. What spine should I start with? I was thinking maybe 2016s cut to 30 inches. I draw just shy of 29. Thanks.

That sounds like a good arrow spine to me,a 2016.I would start full length and trim and tune from there.With a 125 gr. point that would give you around a 500 gr. arrow.

I shoot 27.75 2016s from my 46lb JD Berry taipan which is an 1/8th shy of center and they fly perfect (145 up front)

Thanks guys.

I would go to a 2018 drawing just shy of 29 with 45-50 lb bows.  That extra 2.25 inches of length you need and being cut to center over Brian's above will require the heavier spined arrow. Especially if you are using a modern string material.  Also lets you go up some in head weight for more options.  Usually end up around 550 grains.  The thicker wall is more durable and will penetrate anything you want to hunt in the lower 48.

I also would add to get one of each and try before buying a dozen because the shooter has a big affect on the spine needed also.

Test kit from 3 Rivers, shafts and point kits. Best way IMO to start unless you have a closet full of various size shafts.

I wish I could just buy a kit with a 1916, 2016, and 2018. 3rivers seems to have only gamegetter shafts which are 2016, 2117 etc. I want to buy at least one 1916 to see if that works out better. I'm really betting on 2016s being the ticket, but I have a 29.5 inch 2114 laying around and it shoots stiff, so it kinda.worries me. I could leave the 2016s a couple of inches long though. Anywhere I can buy a test kit for the XX75 camo shafts? Kinda worries me deer season is a month away. My local shop will only sell them in half dozens and he is insisting i use  the Easton arrow chart which always ends up leaving me with arrows that are too stiff. Even the Stu Miller calculator usually recommends arrows that are too stiff by about 10 pounds dynamic spine. The 1916 seems like it might work according to that. It shows 10 pounds weak like my old arrows that flew well. Im going to buy a field point test kit for sure. I am going back to aluminums for the simplicity. Plus I want to shoot my favorite broadhead, the magnus stinger 2 and 4blades. So I'm hoping to get eithier 125 or 150 grain field points flying perfectly. Thanks Matt.

The Easton chart is set up for compound devices. This chart will give you the spine of shafts in relation to woodies. Hope this helps.

Try a 2016 and see if it works.  If too weak, try 2018.  I draw 30", shooting a 69" 50#@30" string-follow Hill-style longbow.  2016's (31" BOP) with aluminum inserts and 125gr field tips fly beautifully out of this bow.  These arrows weigh about 505gr.

I also just shot these arrows out of a 64" 52#@30" hybrid r/d longbow, and they fly nicely out of this bow as well.

Since your bow is cut to center it will probably shoot a variety of spines well. Many of my bows are near 50#, most shoot the 2016 to 2018 well depending many variables like string, point weight etc. If you want a lighter faster arrow use the 2016, if you want heavier and stronger shaft go with a 2018.

go with 175 gr. points & you'll be ready to go with the 2016s at that length on that bow with the Velcro side plate. mine liked 1916s with 125 tips also.

really fine shooters.

[Mryan2176]

Thanks guys, appreciate the help I'm ordering a 1916,2016, and 2018 to try. Im sure I can get one of them to fly well. Bigiron you had a Don Dow? What weight and length? I really love mine. I shouldn't be swithcing arrows now, but the arrows I bought recently didn't last too long and I need some more and really.miss shooting aluminium. I'm sick of adapters, brass inserts, and having to drive 20 miles to the archery shop to get them cut. Yeah I might bend a few, but they are cheap compared to the carbons I was shooting, and I always seem to have an easier time tuning them. They also make 9-10 gpp easily. Anyone here ever shoot a deer with a 1916? I just hope its not too light. They should weigh around 460 grains. Hopefully I can get the 2016s to tune as well they will be closer to 500.
