What’s the heaviest weight .22 cal slug you’re shooting without pushing the gun too hard?
And at what reg pressure?

FX Panthera 600mm - heaviest slug?
- Thread starter Michael
- Start date
Nobody has a 600mm Panthera?
FWIW - I was able to send 36g slugs at 970 fps but it felt like I was pushing the airgun too hard. I think I'll try to stay around 30g.
LMK if you've got any experience with this combo.
Thanks

This graph should be close to representing what a .22 cal Panthera would do with various projectile weights at its max (180 bar~ iirc) set point with the magnum xl plenum and 600 mm barrel. I do not own one but it lines up with what you got on the 36 gr.

Thanks for the graph. I didn't realize the 600mm comes with the magnum XL plenum. But you're absolutely correct

i ran the zan33s at Nac 155reg @ 997.. u see how that worked out... this time i dropped to 30.5s @ 1015 148reg and its nasty to 300yards and happy

22 600mm.....yes for sure but once i heard that i backed it off abit and it sounded happier.. As of right now my panthera is shooting amazing again. I was on the fence on selling it but right now its shooting stupid good even to my m3.. there both on point right now

I like the Altaros ATP smooth 33grain. 128bar, 900fps, 0.18BC and a very relaxed shot cycle. Tried the 40grain Altaros but decided the extra juice wasn’t needed.

I’ve never turned my reg down that low. 600mm barrel right?
Have you gotten any other slugs to shoot good at that velocity?

You could try the 32.3 Altaros 5.52 at about 900 like @weevil recommends BC 0.18 G1. Or try the 40 grain Altaros Kings at between 850 and 900 fps. BC 0.21 G1.
I have a 600 but it’s a .25 cal. I shoot the 49.5 Altaros Smooth at 885 fps or 86 fpe with reg at 132 bar (BC 0.21 G1). Very accurate. Generally shooters think they’re missing out on something by not going 1000 fps. And they are. They’re missing out on much less wind drift and excellent accuracy.

I have some Altaros 31g ATP BT, but none of the smooth design.You could try the 32.3 Altaros 5.52 at about 900 like @weevil recommends BC 0.18 G1. Or try the 40 grain Altaros Kings at between 850 and 900 fps. BC 0.21 G1.

I tried just about ever brand slug out of my .25 Delta Wolf and my .22 M3. Some of my findings are in alignment with yours. None of the lighter slugs performed very well at higher velocities (above 1000 fps). Majority of the slugs that shot well for me were 27g - 30g from 940fps - 975fps. I don't recall getting good results with velocities below 930ish. Does your statement ring true for all slugs, or just the Altaros slugs?

IMHO just the Altaros slugs. They are designed for the 850 to 900 fps speeds. I talked with Ondrej and they are intentionally designed that way. You can shoot them a little faster, but why?
.
In my .22 Red Wolf HP I shoot the JSB KO MK2 at about 960 fps. Also very accurate but a BC of 086 RA4. Better than pellets by a little but not what we’re looking for in slugs.

I have a Panthera in .22 and 600mm barrel. Shooting ground squirrels earlier this year. Approximately 1000, I was shooting the NSA 31.2 slugs at 1025fps. To do this I did install the 8mm hammer. Now just for shooting fun, I took out the 8mm hammer and put the factory one back in. I am shooting the same 31.2 slugs at 980fps. This is at 150 bar and 3.75 on the micro wheel. Macro I think is set in the middle, but it is the micro that is important.

I had the opportunity to do some slug culling today. 10 shot groups (not trying to hit the bull) at 100y in gusty L to R winds.
With my reg set to 140b and the QTS at 2.45 (there’s actually 50 steps between whole #’s) I shot the Altaros ATP 31g slugs at 900fps with good results.
Then I bumped the reg up to 150b and the QTS to 3.19 to shoot the 27g-33g slugs from HN, Javelin, & ŽAN.
I must not have the 8mm hammer because I could only achieve max of 975fps with 30.5g slugs. Where do I get the 8mm weight?
Thanks

Yep -600mm. Micro at 2.9. I was shooting Javelin 26g with same settings at 980. But after trying the ATP smooths, I bought 2000 and tossed everything else out.

I only had the ATP 31g (not smooth) so I ordered some ATP smooths to try out.
I like that i didn’t have to push the Panthera too hard to get good results with the Altaros slugs. But I feel like the ŽAN 30.5g at 975fps outperformed the ATP 31g today. Though it was close.

Panthera 600 has plenty of power for that slug. Also you don’t need 1000fps to be accurate, I always tune my slugs to 900-920FPS max or Mach 0.8. Key to accuracy on any airgun especially with slugs is tune, go with highest reg pressure you can get away with. Depends on hammer weight you should be able to shoot the 35 grain nsa @900fps with about 140 bars.
Personally I only shoot heavy liners and found 217 NSA most consistent. 218 will work but will be harder to push or slower without any gain from my testing. 2165 also works but not quite as consistent and 217, I actually tried them all.
Yes, it will use more air. If you shoot 100 yards or closer then try 27.5g, which is about the same BC as 30 grain. You can zip those 27.5 NSA at 1000fps with ease for fun and giggles.
