I don't know what's going on......but maybe I'll have to listen to a few seconds of this podcast........if I can figure out where it is and how to work it. Never tried one. 🤷‍♂️

Seems like 500 grains is always mentioned as some generic point for diminishing returns for the heavy side of things. What would a similar diminishing return be on the light side? 390? Lower?

I ran a 370 grain setup for a while and it was fantastic. Zipped through a bull at 54 with that, amongst others.

Currently run a 510.

I'd use either arrow on *anything* without a seconds hesitation. I found the trajectory and penetration on game FAR MORE SIMILAR than different.

What’s your draw length and poundage?

I think there's so many variables it's hard to make it about a single aspect.

I find for me it's a point of diminishing returns to be over 295 fps. A lot of it is I find over 300 to be way less forgiving with a broadhead. Mechanical not as big of a deal, fixed blades it really starts to show.


I know and have taken young women hunting that are using light arrows, light DW, and short DL. For them 390grs might be a little heavy. For someone with a long DL, shooting 65#, they probably be just as well to be up around 440-450 as the lightest they go.


Best for people to play with things for themselves, and think about the conditions they hunt.

Correct me if I’m wrong, but what you’re getting at is building a setup around a targeted arrow speed, rather than a targeted arrow weight.

I’ve started building mine that way. I shoot for 290ish FPS. Still forgiving enough on the fixed broadheads, but still great arrow trajectory.

Shooting animals with a trad bow really opens the eyes to the “energy” conversation. As you said in the podcast, as long as an arrow is flying straight when it hits the animal, and the shot placement is good, it’ll be lethal.

I’m much more confident I’ll get good shot placement with a flat trajectory.

Yes, again, with respect to variables.

It's about targeting an arrow speed, when you are confident you aren't loosing too much otherwise.

Lot of times DW is used to make the speed up, that's not always the best option. No point in shooting 75# to hit 290 fps when you are much more accurate with 60# @ 260 fps.

In above scenario I'd loose 20-30grs of arrow weight if I could, try 65#, and see how that works. Because I hated being that "slow" personally. It's relative.

As a total newb to archery I actually thought this podcast made sense on a subject that gets batted down all over the internet. Much to think about but thanks for laying out the tradeoffs in a clear way.
