Heavy arrows have better trajectory?

I do find it hilarious that his example at 7:49 of a HORRIBLE pin gap with a light arrow is showing gaps from 10/20 to 90 yards :LOL:

No mention of pin gap being affected by peep to pin distance in addition to arrow speed.

I packed three bull elk out of the mountains last week that were killed with middle of the road arrows and mechanicals. All complete pass throughs, short and substantial blood trails.

The heavy arrow weight and tiny broadhead deal is blown completely out of proportion. Don’t hit heavy bone in the first place, and you don’t have issues.

he needs to put a full cap on, so that the brain receives less "baking", is he on some drugs, 'cause he looks like he may be. But again he has been doing it for 10 years....

I would say that in his best interest he should stop drunk posting... or posting in general.
I always think that when I see him, like is he just getting out of coaching baseball practice? Keeping the visor alive solo 😂

That's only part of trajectory, and the distance at which the slower speed decay becomes relevant is way farther than anyone is shooting a bow.

Look at TAC shooters and other long range shooters and you will find no one shooting heavy arrows. Josh Jones (MFJJ) was recently discussing how he can shoot out to 200 yards with his bow and it's because he's shooting 80+ pounds with a 30" draw and a LIGHT arrow, I believe about 350 grains. He said he couldn't shoot that far and be able to use a pin to aim with a heavier arrow because he'd run out of clearance with the scope.

I see the argument that light arrows loose speed quicker/there’s a greater loss in speed vs heavy arrows because physics. Absolutely true, but that argument always neglects to mention that the fast light arrow, despite loosing a greater PERCENTAGE of its speed, is still FASTER than the heavy log.

Just for example, a 400 grain arrow that’s 290 for at launch is moving at 260 for at 60 yards, while a 500 grain arrow is 260 fps at launch and 240 at 60 yards. So sure, there’s more loss with the lighter arrow, but on the flip side at 60 yards it’s moving faster or as fast as the heavy arrow started.

How dare you make a fact based argument on the internet???

I wrote an "article" last year in May or June titled "Proving the RanchFairy WRONG " people should go look it up!

Any bow is at its absolute most efficient with a 450gr arrow, when you go aboulve 450gr your speed love VS energy gained starts to go sideways and you are loosing more speed/trajectory than you are gaining in energy!

Very interesting, never heard this before, definitely going to look it up and think about it, thanks for sharing!

Lol 😂 I had to leave a comment on YouTube. That the 30 yards difference is the main factor in the gap ... He missed that....

I also asked in reference to the female hunter pin and ezV sight. If her gaps at 200 fps where not 5 yards increments instead of 10????? Something else to consider...

I've killed hogs with 360 grain all the way to 630, how dead do they need to be?

Fast forward I still shoot 630 out of 60, and a 470 out of a 70! All broadheads are hand sharpen to a razor edge.

YouTube is entertaining, so is Archery Talk.,😂

Yep... I've killed a PILE of critters (deer/turkey/hogs) with a 370gr arrow and had exactly 1 instance where I didn't get a full passthrough. (my broadhead stuck out the far shoulder about 4") I recovered the deer and thought "Maybe there is something to this heavy arrow thing?!?!?!?!

The next few seasons, my hunting arrows were 615gr and I killed another pile of deer. But, the only time in my life where I NEEDED a follow up shot was with these 615gr arrows. (He tried to duck the arrow and I spined him)

I've since figured out a middle of the road arrow (7-9gpp) is the right compromise for me. When customers ask about heavy vs light, I advise them to stay in that range for a favorable trajectory and enough energy to get the job done and normal hunting distances.

e=mfc2

e being energy
m the constant of Mathews
fc2 is front of center squared

This equation represents the mathematical fact that any Mathews bow shot at an elevated position at a downward angle with an exaggerated foc weighted factor squared will always achieve a maximum arrow velocity equal to one-half of lightspeed. Therefore a flatter trajectory.

*Unless said arrow is shot out of a Whisker Biscuit, then a standard deduction of minus ten fps must be applied.

His analogy of why you want a pass through and there is medical science proving that you dont want a shaft in the cavity pissed me off. Compairing it to if a human was impailed by a metal rod the dr. Would want you to keep it in. Yes, but the animal aint gonna lay there like oh **** dont move let me call 911 LOL!! That animal is running for its life busting through everything and that broadhead if inside the cavity is just grinding away causing more damage!!

You haven't killed too many game animals have you?

Time of flight.

Yes gravity is a constant. Yes, both arrows will hit the ground at the same time. But you need a **** ton of poundage to get that heavy arrow launching at the same velocity in order to cover the same distance using same trajectory (same TOF).

Anecdotally I use two bows for Africa and take 2 sights for each bow as backups. In order to get the same POI I would need to use the 40 y pin on my 70#/490gr bow to get the same POI using my 910 gr arrows @ 20y, or use my 20y pin on my 75# /910 bow and be a little high @ 40 with my 490 gr arrow. Easier to swap out sights if one bow goes tits up.

Going light this year: 455 gr & 875 gr @ 70/73#.

ps God bless him and his hard work, but Ashby's assumptions are wrong. Pity, hats off to him though.

But that does not make it right, nor does a heavy arrow give you a license to do so, just because some DB named after some salad dressing says so... Every animal deserves a fair chance at a quick and ethical kill shot...
It's statements like this that make me dislike the RF even more... too many people think because they snort the fairy dust, they can take sketchy shots. I've heard so many people say "I shoot XX pounds with a XXX+1 gr arrow.... I don't fear the shoulder"... Coincidentally, my buddy with the tracking dog says people like that are the reason he's in business!!!
Just going to take a moment to point out the hypocrisy on multiple fronts here. Y'all bash on Ashby for using Cape buffalo to collect data because they're so large and bone dense that it's totally irrelevant to whitetail, but simultaneously believe that nothing short of a javelin missile can penetrate a deer shoulder and therefore it's unethical to attempt such a thing. You also didn't have any problem with the idea of taking extreme long range shots and the ethical implications of that.

For the record, I personally align somewhere in the middle and certainly don't go out of my way to shoot at shoulders. I also don't hinge on Ranch Fairy's every word like you think, but I do know there are deeply troubling contradictions within the light arrow side of the community. You've absolutely proven my point, so thanks!

1) I didn't see anyone advocating for long range shots in this thread and MOST folks here are quick to jump on anyone who wants to launch those bombs.

2) You don't need a Javelin missile to penetrate a deer shoulder... but it isn't advisable with archery equipment. My buddy runs a tracking dog and a large percentage of the deer they find, are shoulder hits.

3) I don't bash Ashby. But I also don't necessarily believe his (or the foundation) word is gospel. Modern compounds have plenty of potential energy which is a component of penetration.

4) As I've mentioned in this thread... I've spent time in both camps and also have found my gear seems to perform optimally in the 7-9 gpp range. For me, that's in the 450-550gr range. It gives me a trajectory that I can live with and plenty of "oomph" when the metal meets the meat.

You are 100% here.

God forbid anyone goes out and does their own legwork other than point at a screen, and say "look, this person said XYZ..." . I get it, some people have run heavy arrows, because that's what works for them or what was used by their father, uncle or Grandpa, and others lighter setups.

But the worst part is that when people that are relatively new or have to keep up with the Joneses stick to what some Shill on YouTube or IG has to say as the absolute end all!

These arguments never get this "sensitive / serious" at Deer Camp, with the Warden, or while shooting the breeze at your Archery Club... admittedly, I have taken advice when hunting out of state from friends that live in that state while hunting and have had success in whichever animal I / we are pursuing because that is not my common game type - yet this relates more so to broadhead usage vs. arrow weights.
