2117 tuning

[Oldtom99]

Hello all, this is my first post to tradgang so please tell me if this belongs somewhere else!
I recently acquired a 1965 Bead Kodiak mag 52# @28. My draw length is 28 and I’ve begun the tuning process with 30.25” 2117 gamegetters with 175 grn points and standard 29 grn inserts. I’ve used this configuration for other bows so thought it would be a good start. Fletched arrows fly like darts but bareshaft shows on the stiff side. Going to try 200 grn up front which would match the broadheads I hope to use (razorheads with steel inserts). Does this reading seem correct or is this a “false” stiff?

You're in the right place. Welcome to TradGang!  You seem to be on the right track. Try a 200 grain point and see what happens. Probably not much, since 200 grains isn't that much of an increase from 175. Alternatively, you might try a 2016, which would allow you to cut down the length of the shaft a little. I've never heard of a false stiff, but what do I know?

Mcdave-
Thanks! Really enjoy the 2117s so going to give 200 a try when I get some more field points in!

I have a 28” draw also.
I can shoot 2117 with my 49# and 50# bows, but as McDave suggested, 2016 works better for me at 29”.   I have shot that length for a very long time now and am just used to it I guess.

Might think about a 2018 as well as it straddles the difference between a 2117 and a 2016. It's a much more durable shaft than a 2016 if it works for you. I guess it all depends on 'how stiff' you show with the 2117....especially after you add the extra weight.

2117 are .400 spine so I would expect them to be stuff at that spec, which means you are likely getting accurate results.  I wouldn't be surprised if you end up needing 250 grains up front.  That will make for a heavy, but powerful arrow. 

One other thing to verify is your draw length.  So many people greatly over estimate their draw length. 

You are on the right track, add weight in small increments until the bare shaft tells the story.

I love them. Probably my favorite shaft, but I leave them full length. By doing that, I use a 145-150 grain point at my 28” draw and mid to high 50’s pound bows. I need a new outside target!

Hello and welcome to the gang , lots of knowledge here. A 2117 shaft is quite stiff , I think for your setup and specs at that weight I use 1916’s with footed ends and 175 grains they fly like rockets. You could also try , like others have said a 2016 ot a 2114 , they both spine at 62#s

I agree with this 100%. I don't know if you would ever get a 2117 to work. I shooting some right now out of a 57 pound bow. I've shot 1916 and 600 carbons out of a set up like yours,or gone to 500 spine with a heavier tip.

[Steve Clandinin]

Yes , you gotta love aluminums, I’ve been shooting them for around 60 years.The darn thing is there’s a big gap between 1916’s spined at 50#’s and 2016’s and 2114’s spined at 62#’s with nothing in between , which is what most people shoot. I would love to see Easton bring back the old 1918’s and 1920’s, I think they would sell well.

Well dang  the ole 3rivers spine calculator suggest with a 200-250 grn point I’d be pretty under spined but I’ll have to see what happens when I get some heavier points in.

[Steve Clandinin]

Hey Jake, I know what your saying, I have some old Easton spine charts from the late 70’s and early 80’s and what they recommend I have found is there way to heavy , for me. Through experimentation I found what works for me and my setup and I’m sure you’ll find the same, and this probably apples to everyone.

UPDATE!!!!

I finally got some various weight adapters in to fine tune my setup. After a lot of shooting I have found that an even 300 grains upfront makes these arrows fly like darts! With perfect release I was slapping bareshafts at 15 yards with no fishtailing or nock left/right. With wrapped and fletched arrows, the total weight comes out to 716-720 grains. Due to me living at an apartment for college my target setup on a local farmers property is merely a “black hole” target set on top of an old folding metal chair. My first shot with the fletched arrows went through the target and penetrated about 2” through the back-rest of the metal chair!  talk about a powerful arrow setup! Out to 25 yards these arrows still had great flight and when tipped with a sharp bear razorhead, penetrated to the fletchings.

I like good arrow flight, but I am not a tinkerer. When you said it flies like a dart, that's a s far as I would have gone. I would simply take them hunting. I used to shoot 2117's from a 68" longbow drawing 58# at 28", but I only pull 25". They performed very well for me, flew like a dart. It does seem that you have found a likeable combo with considerable point weight. Good hunting!
