Arrow testing - Pick the best

Curious as to if you’re using a form of archery software while expirementing with these builds? Archers advantage or software for archers. I run both and they’ve really helped reduce the quess work for myself, family and friends rigs. I also run an arrow configuration similar to your #4 build ( raw shaft is 29.25”, .300 spine FMJ with AAE stealth and 100gr tips) FOC is low (~9%)compared to “suggested” but has plowed through elk at 55 yds. If you like I can run some numbers for ya! I will be configuring a 4mm FMJ with the new titanium outsert from Easton to retain my standard 8/32 threaded points and heads anyways.

I'm not using any sort of software or app beside a calculator and the  chronograph. You are more than welcome to run the numbers and see what your info says. I've never seen or heard of those before and have no idea what they do, so I'm all ears to hear what they say and to learn more.

On a side note, I received the 150gr heads last night and threw them on the scale. The we're all between 49.8 and 50.2 good enough of me, my shooting and my testing.

My arrows now are pretty much identical to #3 minus about 10 grains. That being said, for no good reason I'm doing the same as you and going to play around with some 150gr points this year and see how I like them. It'll put my arrow weight just short of 480 grains.

Got the arrows cut down to the shortest they can be with my rest and riser.  Here are new numbers.

#2.  1 is too light, 4 is too heavy.  I picked 2 over 3 due to the FOC.

I've killed a ton of stuff with similar sit ups to #1

[92xj]

I've killed a ton with that #1 setup.
Me being me, it was time to tinker, run some numbers and do a little changing for the next few seasons.
As of right now I have decided to run the #3 with the shortened arrows and 150gr heads.

Axis 5 mm         150gr head
Length tip to tip 28.312"
Total weight        458.9gr
FOC                  12.25%

#4 but #3 would be ok

[92xj]

Well, this whole test is for the birds... I bought a new bow.
 Now shooting a centergy. 71.5 lbs, 28.5 draw, 150gr heads, 4 Fletch max stealth, 27" carbon to carbon axis 300s. Total arrow weight is 500.7grains at 272 fps.

I would be interested to see which ones grouped the best. I would think a 29" 340 spine arrow at close to 500 gr shoiting 70lb would be underspined. I'd have to run the numbers though.

I personally try to build and arrow set up that maximizes the grouping and forgiveness to flight keeping speed to a minimum of 280fps with a target of 300 fps. I want to be in the stiffer side of suggested spine range no less tha 400-410 grains total weight and no shorter than 29”. I also want my arrows to all be within  .001” of staightness at a minimum.  Some suggestions to help your arrow set up is to lighten up the knock end by getting rid of the wrap going with the lightest knocks. You already had gone to 3” four fletch which is a huge improvement for fast arrows with broadheads. You need to keep your FOC at 11% or slightly better and going to a fixed broadhead with as little sideprofile as possible and as close to a cut on impact tip as possible for best penetration. Go online and get an arrow build software like archers avantage it will save you money in the long run. The thing you are missing in your test is your long range grouping test. I make my final decision by shooting and testing my grouping first at 40 then 60 and finally at 80 yards. If my groups at 80 yards with broadheads don’t match my groups with field points then i know something is wrong and i make adjustments until it is fix and that arrow setup never makes it to the field until it does.
