Pellets forward or backwards - does it really matter? Spin or no spin?

I bumped into the above video and it shows a larger diabolo shaped pellet being fired forward and backwards out of a shotgun (smooth bore) and also a rifled shotgun barrel.

It appears, and would need more testing, that the spin doesn't help and forward or backwards with no spin is just doesn't matter.

Hmmmmm, things are always more complex then what you think.

Thanks for sharing...

One would be really surprised because few good quality high end PCPs I shot could actually do large ragged hole groups at 50 yards shooting some select pellets backwards...

Now everyone is gonna try to shoot their pellets backwards... start at 10 yards and go further to see how far yours can do it...

I have a Daisy 717 pistol and can plink at tin cans at 20 yards shooting pellets backwards.

They aren't as accurate as shooting them the correct way but interesting to find out how they do...

I am preparing a followup to my Vendetta inquiry BTW... Still sorting out my PMs...

CA,

I'd be more interested if someone wanted to borrow my hack saw and take a couple inches off their smooth bore FX Liner 😁 Of course they would need to re-crown the end, and possible lose some slight power.

Who's willing to sacrifice for science?

Would be interesting if the ballistics would improve if they filled the cupped/skirt end with polymer. That hole has to slow down the pellet I would think.

I don't have a CRAY computer to run any aeronautical simulations on, damn, I need a better paying job.

We know the flow definitely isn't laminar, and there is probably some extra drag coming off the head onto the skirt. The biggest drag would probably be as it swirls into that cavity in the back. How it all works could be interesting to play around with.

Wadcutters are widely viewed as short range pellets. Seems a pellet in "backwards" would behave much like a wadcutter with that flatter/less aerodynamic front section causing higher drag but the domed rear would behave more like a boattail to help reduce drag. Coldair notes less accuracy even at close range and apparently further loss of accuracy at increased range. Seems logical.
