Thought this would be interesting given all the controversy arrow weight seems to generate. What is the lightest arrow weight you or someone you know achieved a complete passthru on an animal? If you know the size of the animal and any bone hit would be helpful info. Sure, there's alot of factors going into penetration but lets focus on the arrow weight.
I'll start myself:
288grains-250lb Russian Boar, ribs cut on entry and exit. 276grains an adult whitetail doe.

351gr flatline through a 200lb whitetail buck. Cut ribs on entry and exit, complete pass with several inches buried in the ground.

The distance to the animal will have a significant effect on arrow speed on impact. Light arrows slow down fast.

 

[BP1992]

Never used an arrow under 400 grains.

My set up use to be a GT Expedition 55/75 and a 90grn MUZZY 4blade which was around 348gr total and it passed through every deer I shot with it from 5-40 yards.. It was only chronoing about 275 -276 so no speed demon at all..

That's about what I'm averaging speed wise.

I used a 355 grain arrow one year at 285 FPS and easily passed through a nice buck. I try and stay right around 400 grain now.

 

[HOOSIER55]

313 grain arrow at 318fps 69ftlbs ke passthrough with a rage 3 blade on a doe quartering away arrow went through ribs on the way in and out the opposite soulder and into the dirt, 63 yard shot

 

[completepassthru]

A 310 grain Victory HV and big 2in. mechanicals. I killed alot of deer with that arrow last year and all passthru's from a 90# doe to a 200# 11pt. I shot a 150# doe quartering to me in the shoulder bone (not scapula) going in and came out the back of the ribcage. The arrow was laying on top of the ground but not stuck in the ground like all the rest were. In 2010 i used a 336 GT Velocity with the same results.

I used a 350-360 grain arrow from 1998-2009 and then dropped poundage and arrow weight.

It just does not take a heavy arrow to shoot through deer.

 

[wildthing]

354 gr. Lightspeed with a 3 blade 1.5 in. expanding broadhead at 320 fps no problem going through deer.

 

[justanotherbuck]

330

 

[brutus69]

388 grs, its the lightest arrow i have ever used

 

[lovetohunt93]

I won't shoot under 400 grains. But 410 for me on a doe.

Actually, that's fletching. Smaller faster arrows can use smaller fletching (less weight to stabilize, and more drag force due to the speed), and then they keep speed and energy much better than heavy ones. But, not as accurate with fixed heads.

 

[crazy4hunting]

350 velocity on adult doe with slicks. 20 yard shot, arrow in ground 4-5 inches.

 

[makingscents]

300 grains for over a dozen years.
Pass through every time up to 50 yards.
I never hit the shoulder bone though

 

[Yooper-travler]

Man I can't recall ever shooting anything under the 420s. But even at those weights not all my shots have been a passthru.

What is your bow speed?

 

[Viper69]

Passthroughs depend on shot placement more than anything. You hit bone your in trouble most of the time.

 

[TREESTANDSNYPER]

304 grain Easton Flatline shot from a New Breed Genetix set at 26"/60 pounds. Complete passthrough on a mature whitetail buck. Shot was through both lungs, and arrow buried itself in the ground several inches. You can see where the arrow came out (just above my sight in the picture). I was shooting a 100 grain Rocket Steelhead (expandable) as well.
