Ghost Spiralling pellets?

[Corvid_Hunter]

I was watching this video and noticed what looks like spiralling pellets. It happen 2 shots in a row. In the video description it says 25gr JSB Redesigned at 934fps. Start at the 8:30 mark.

I agree, it sure looks like that was spiralling!

Maybe a good barrel polishing and cleaning might fix it.

(Polishing won't help) They all spiral. Every diabolo pellet leaves the muzzle with a little yaw, and the spin turns that into a small corkscrew. Some pellets show it more on camera, but they all do it. Sizing just makes the spiral smaller and more consistent.

I don't know about helping the spiraling on mine....I'm not sure they were spiraling in the first place, but it sure helped to improve the accuracy, that's for sure.

Polishing can definitely help accuracy by smoothing out the bore and making the pellet engagement more consistent. But that’s separate from spiraling ,,all diabolo pellets spiral a little as the yaw damps out, and polishing doesn’t change that. So your accuracy gain makes sense, but it isn’t related to spiraling.”

Ted's holdover had a video on accuracy and spiraling and it showed when he cleaned the barrel the spiring went away and accuracy was greatly improved. It's a very old video he put out.

They certainly will spiral when shot at the wrong velocity. You might try backing off from your current velocity 10 fps at a time until it settles down. Pellets like speeds around 860 to 920 fps.

I remember watching that video and noticing the spiraling too...then looking in the comments section and noticed other people saw it as well.
I shoot Mrds 975fps and get amazing accuracy with em, Marno is shooting the same gun, same barrel twist, and more than likely the same pellets, which can easily handle 930fps with a slow twist. Something is definitely up, dirty barrel my guess or too much reg pressure/or H. spring on max!?
I've watched the FX hunting vids where pellets or slugs can spiral in the slowmo footage and quite often still connect to that pest way down range... Its never desirable of course.

Spiraling isn’t a ‘wrong velocity’ thing. That’s just the pellet’s yaw doing what it does, and every diabolo shows some of it. Changing speed can make it look bigger or smaller on camera, but it doesn’t cause it. Just sharing what I’ve seen in the real world.

Which version of the MRD are you shooting? The shallow or deep skirt? I was going to order some for the Delta Wolf and don't know which one I should order. I'm pretty sure the Daystate and BRK barrels are the same as they are interchangeable.

My Ghost likes the deeps (which resemble the regular Mrds closely) vs the shallows, but its definitely a toss up what works best for others. Rewatched the video and something is up....Marno said he checked the twist and thought it was 1:17 or their about. Pretty sure the Ghost Hp .22 only ever came with a 23inch 1:30 poly. The ghost plus (aka the compact) has a 17inch 1:17.7. He also says its one of the first Ghosts so who knows what barrel was in it

However IF he was shooting a 1:17.7 then 940fps is about the (speed) ceiling for that twist rate and that may be the answer for the spiraling pellets farther out.
Lastly... The .22 Ghost hits hard!! Ive taken 3 coons with mine, all 1 shot to the dome. Zero follow ups required.

Did you try the 20gr and 28gr Grands?

Did you try the 20gr and 28gr Grands?

I did, the 20gr Jsbs are the lightest pellet mine will shoot well on minimum with stock spring. The grands were not great.

Thanks. I'll stick with the 18gr and 25gr JSBs and call it a day.

Might depend on which barrel is in that gun. The 1:30 or the 1:17.7? The 1:30 at that speed seems about right but may not have enough spin stabilization causing the pellet to act like a pellet stabilizing as it goes creating the illusion of a spiral. I would call that a wag with the pellet trying to stabilize as it flies. It might be something where the 1:17.7 twist would stabilize the pellet out of the barrel and create less wagging while in flight.
