Crazy Spiraling .177

[Bramezy]

So each gun ive shot 13gr in all
Spiral at 50yds. 785fps up to 850fps.
From a marauder, wolverine, raw, avenge-x, airarms etc…
12 groove Lw poly barrels too.
Ideas? Have cleaned the crap
Out of them and tried all brands of 13gr without any success.

Also see it in 10.3gr at 880-910fps.

Have always heard reduce speed but i havent gotten very slow yet to try. Requires deeper tuning.

Never seen it with the 13.4s. 16.3.....yes.

Do you use a moderator?
Since the speeds are in the "no-spiral" range, and you indicate that it's not a barrel problem, perhaps they're hitting something in the moderator.
One other thought is a bad barrel crown that's "pushing" them off on exit?

Yes mods but happens on every gun

Sometimes my S510 barrel shifts to the right or left, and the barrel band will hold it in place. I'll have to center it again if I see a significant shift in POI. I've never seen a pellet spiral, though.

What's your reg set to on all your guns?

The only spiral i have seen are from Beasts and +20 grain slugs, and it look absolutely bonkers with the sun in the back.
I have no doubt also encountered it with other pellets CUZ i have tried most outside of their comfort zone, either by accident or deliberately out of desperation.

My maverick in its original 600 mm form would shoot MRD pellets lights out under 600 fps, but 700 fps and up speeds was a absolutely nightmare, probably also due to pellet spin.
Maverick back to 600 mm now, but that original barrel is not coming near my rifle again.

Okay i have also some times seen slugs on the way to 134 yards be like " that one is not going to hit squat " and then somehow it still do, and i am like WTH

I stopped shooting the 16gr Beasts because of this issue. Pretty sure it cost me a few $$$ at the 2023 PAC gunslinger.

I’ve tried pushing them anywhere from 800 to 920 out of my AA S510 and I can’t get them to be consistently stable. At least 3 out of every 10 would spiral

13.43gr MRDs don’t have this issue. They are flawless from 820 to 940 out of my 12 groove 17.7” 495mm S510 barrels.

Enough wind may cause spiralling from any air gun.

Thats what im starting to wonder. Ill retest indoors vs outdoors. Have all winter!

 

[thomasair]

It's not the wind. That's the most used pellet for 20fpe ft. It wouldn't be if it was prone to spiral.

 

[thomasair]

Are you talking about the redesigned or original? I don't use the redesigned...but the original won't spiral out of a well prepared barrel even at 100y.

 

[nobody1]

Spiraling may also be caused when the pellet slows down towards the end and the pellet velocity becomes too low.
I had spiraling like that and increasing pellet velocity eliminated the spiraling.

The farther away your target the more initial velocity you need to avoid spiraling.

Spiraling from two different .177 pellets (13.43 and 10.34) at speeds that hundreds of guys are shooting them from (my estimate of ft participation, nation-wide since we're talking 19fpe), shot from the same guns that hundreds of guys are shooting them from, using the same barrels as everybody else in field target, and at the typical speeds?

Something doesn't add up.

What is making you conclude theyre spiralling?

Im wondering if you've got realistic expectations.

Realistically, groups under an inch at 55 yards (outdoors) with a 13.43 or a 10.34 is typical for a good field target gun in minimal winds, when shot from one of the ft legal positions. And that's plenty accurate to win matches. Very rare are guns can shoot mostly 1/2" groups at that distance, and only when the wind is cooperating (hardly any).

Guys have a hard time separating what their guns are occasionally capable of, versus the average group sizes they're getting. If you can keep most of your shots in the 1-1.25" range at 55 yards with any wind at all, you're doing just fine.

Don't fall into the trap of comparing what you're seeing from your guns to what people are presenting here. From the average person sharing, reported accuracy on the forums is like eulogy's. We only hear the good stuff. Not the fact that the dead guy kicked his dog and beat his wife and came home drunk every night and served time in federal prison when he was younger.

I can shoot beasts like lasers to 50 M, but its like something happen when they go a little further, and way out at 86 - 123 M distance it is just a epic mess.

But you can bet i have some beasts for short range high smack applications.
Only have 1 tin of monsters and i have never tried those in any rifle of mine.

Same go for say 24 grain slugs, i can shoot them pretty fine at 55 M but longer and they do make keyhole shaped holes in targets.

 

[rong1966]

That's interesting. The original 13.4's spiral in my Revere, most notably at 50 yards but probably closer as well. I estimate 1 in 5 fliers, more when there is a cross wind. I have only shot one tin of the redesigns, but I can't recall any spiraling with those. I may try increasing velocity to see if that helps.

Both and FX13gr. As stated out of many of my guns.

My expectations are MOA accuracy consistently. 55y max so .55”.
I get wind but consistently id like to find MOA. I dont care which gun or pellet really. Im just wondering id the wind is causing my spiraling but pretty sure it happens indoors too.
As you stated many others are ahooting the same pellets, same speeds and same rifles without these issues. How the hell am I prone to not just one but several?
Something does not add up, your correct there.
Ill test a dozen different pellets in each gun.

 

[thomasair]

I'd take off any moderators or barrel attachments first and try. It's not the pellets.

I tried 100y since 25y was so good, couldn’t see my impacts because they were so spread out!
