First pin opinions please

[DoubleJ]

what set up are you shooting?

AR-34 Don't know my actual speed but IBO for this bow is 315fps.
27" draw
67lbs (WAY too much for my shoulder but I'm working out to make it work)

Carbon Express Piledriver 350 cut at 27"
125gn Magnus Snuffers
Zeon Fusion vanes
Carbon Express inserts and nocks
Total arrow weight: 444gn

My KE calculator has this setup at 214fps and 45.4 lbs of KE

I am pretty sure I can drop to a 100gn head and gain a few FPS without giving up KE but, FOC is going to drop.  I'd like to go with 85gn heads but, I think that may throw the FOC off too much.  And I kind of feel like the "punch" of a 125gn or 100gn is worth the speed trade off.  Am I correct in thinking this?

According to my calculator, my FOC right now is 13.2%
FOC with 100gn head is 11.1%
FOC with 85gn head is 9.7%
Thoughts?

Damnit, now I feel like I'm way overthinking this

  maybe you have too much foc causing the rapid drop? try 100 grn tips once and see.. are your field tips dropping 6in as well? as I said in another thread I have a spare or two 100 grain monte cs you could give a try if yah want. 
as far as your sight, you know you best. set it how you feel it should be.

Why not just set your first pin at 25 yards and be 3 inches high or low depending on if you were at 20 or 30? 

Wouldn't that solve your problem?

[pullnpray]

are your sure your arrow weighs 444gr? thos carbons a 11.3gpi right? you factored in the nock and insert weight and vain weight? your FOC seems to be high but thats what im personaly thinking have you paper tuned/ walk back tuned your bow yet? im also showin a bow with those specs shooting a 473gr arrow(thinking it might be closer to what it actually weighs) 236ft/sec here is a good ibo/foc/arrow weight clac http://www.backcountrybowhunting.com/articles/calc/

I have the Piledriver 350's at 10.3gpi, not the piledriver hunter 350's that are 11.3gpi

And I have a D-Loop with peep and cat whiskers.  Estimating 100gn on string

Going to try 100gn and 85gn tips later.  I have both.  Couldn't tell you about field points yet.  I was working on BH tunning and hadn't put points on yet

[pullnpray]

or wrap your arrows and throw some lumanocks in them it should drop your FOC down a bit.. if you really want to stay in the 125gr BH category remember to tune your bow after you choose which one each ones gonna fly diff.

If you haven't shot field tips yet how did you broadhead tune? True broadhead tuning involves moving your rest in small increments and shooting a field tip and broadhead until they both come together.

Chit.  I'm doing it wrong.  I thought it was shooting BH's and moving the rest in small incriments until they're hitting bullseye THEN shoot points and adjust the sights until they're hitting bullseye

hey Double J,

Do you ever get out to east King County?  I live in Duvall, WA and have plenty of room to shoot.  Also, been shooting bows for over 33 years, and can get you & bow tuned properly in short order. 

You should be shooting field point thru paper first.  Look up paper tuning on Eastmans site.  After you paper tune w/field points (i.e., shooting a bullet hole thru paper from only a couple yards from paper).  Step back a few more yards and make sure you are still shooting a bullet hole.  This will get you real close to shooting field points and BH in same spot.  After shooting thru paper, continue using FP's and set your sights; 20, 30, 40, 50, etc.  If you aren't comfortable shooting longer distances yet, just set up 20 & 30.  Make sure you are grouping your field points before switching to BH's.  You should not need to move sights at all to get same grain BH to hit same spot as FP's if your bow is tuned properly.  If they aren't same POI (because BHs can magnify any slight bow tuning issues), then you make very slight adjustments to rest based on where BH's are impacting.  Once FPs and BH's are same POI (i.e., ignore moving sights until FPs and BHs are same POI), then you can move the sights (if necessary) to bring you back to bullseye.

Also, based on your comment about shooting 67lbs and it hurting your shoulder.  BHs will also magnify any imperfections in your shooting form (i.e., might be you, not the bow tune or BH's fault).  I would turn the bow down a bit and make sure it is comfortable to shoot.  Once you are grouping your FP's and/or busting knocks at 20 to 30yards, then you can crank up poundage a little at a time until you get to your desired hunting weight.  Also, only after your shooting form is good and you have reached your desired hunting weight, now is the time to try to get BH's to fly correctly.

Hope this helps, and if you want to come out to Duvall area and shoot, just PM me and I'd be happy to help.

Nice offer ET!

I shoot a two pin mover top pin fixed 37 yards six inches high at 20 yards bottom pin adjustible from 40-90. I set my bottom at 50 and move from there .
