800mm FX barrels, when will they be available?

As many have mentioned above, the goal is heavy lead without having to push the gun as hard in most cases. Occasionally, it would be for the extra top end power when hunting as well. I almost exclusively shoot slugs nowadays, so more power/ same power easier is always welcome. Of course, I could sling almost any pellet supersonic already, but that isn't an issue with the heavy slugs. Rounin ain't wrong! A carton or two of old eggs from the store can be a heck of a lot of fun. Popping those eggs at very long range is a hoot! He's the one that gave me the idea with the old eggs, ha! I would really like a .30 800mm just for the top end power potential in hunting. Hunting is primarily the reason I even shoot .30.

I've seen the 800mm prototypes being used in .22 by a few of our favorite FX shooters on youtube, and was hoping someone may have some insight on when those or other long barrels will make the jump to retail. Thanks for any info guys!

I shoot 66gn slugs from a 700mm barrel at 948fps average on 150 bar. I'm surprised that the gun has such a sharp recoil at this level. It's about the same power as a .22LR but the recoil from a .22LR is almost unnoticeable.

I don't think I would like the length of an 800mm barrel along with the suppressor unless I only shot from a bench. I use two FX suppressor center sections with 3d printed baffles in them which is about half the sound from a Donnyfl Ronin. I sold my Ronin within 5 minutes of making this discovery.

That's about the same power level I shoot my Maverick at in .30. The length doesn't bother me much, within reason. I normally use the STO suppressors, and it works quite well. the harder you push them, the better they seem to work. The recoil doesn't really bother me, since most of my shooting prior was from guns with far more recoil. I figure another 4" won't kill me, given I don't do a lot of "walk and stalk" hunting with the .30. I'm usually sitting and waiting with it. If I can get the gun up another 10 fpe without having to push it so hard, the extra speed would be nice. The faster that slug gets on target, the less room for critter movement causing issues, and the extra juice will just help insure a humane dispatch on larger game as well. I literally only use the .30 for larger game like hogs(and hopefully deer this year). The law in GA only requires .30 for air gun hunting of deer, and that is almost the sole reason I even have a .30. Since our guns are pups, it's not so bad. Now a traditional rifle with that barrel would be a no go for sure!

The .22 is used most for pesting from a rest/bench or targets, so again, the length shouldn't really matter to me there. I can always switch to one of the shorter barrels, if doing a lot of walking around. I mainly want that extra length to go easier on the gun and up it's potential a bit. I've had mine up to 136 fpe in .30 for hunting, but I don't like pushing the gun quite that hard. I've had it up to 85 fpe in .22, but as with the .30, I don't like pushing it that hard.

Very cool design with that moderator, btw!

How much pressure are you running to reach those power levels? I only mention recoil because I feel like it can change the point of impact depending on hold. The more the gun moves between the time you pull the trigger and the slug leaves the gun greater the chance of missing the mark.

SC requires .30 airgun for deer also but I'm not to into deer, I'd like to shoot some pigs though. I'm working on a new valve housing design to get the power much higher in .35 but the cocking system needs reinforcement to be safe. Broke my foot recently so I haven't been out to the shop much.

That's the perfect question there! As I'm sure you know, the Maverick valve doesn't have the flow capacity of the Impact, so it does require running a higher reg setting. I have the Huma extra high pressure regs in my Maverick, along with a little bit of valve work etc. I have to run the second reg around 170-ish bar to get to the 130 fpe mark in .30, but it will do 120 fpe around 155-160 bar. That smaller valve seat can only do so much. I opened the valve seat up to 7.2mm and made a PEEK poppet for it, which helped a little. The cocking linkage is the weak point on my Maverick as well. At least, when pushing the gun past 130fpe anyway.

You're going to laugh, but I prefer shooting the .22 at the pigs, since I only do head shots. The .22 will get to the fuse box quite well in the 70-80 fpe range on any sized pig, inside of 50 yards, and the gun is quieter and more efficient with the .22. I imagine the .25 would be the best of both worlds, and they can do 90 fpe without too much hassle, while likely penetrating better than the .30 would.

Rallyshark do you have more info on the two FX suppressor center sections with 3d printed baffles. I would like to know more.

That's heavy-impact that did the suppressor modification. I'm useless in that department, other than saying buy a good one, haha.

Any reason you guys wouldn’t rather use 40-44gr slugs in .22 pushing them close to 1000 FPS? 

that appears to be the most common trend in slugs right now. BC must be really nice. 


im slowly collecting different accessories to start shootings slugs myself. By mine is .25…in the back of my head I’m always wondering if I shouldn’t going after .22 for slugs.

For me, the reason not to use the 40-44 grain slugs is pretty simple. The first reason is they won't fit my magazine. I could get an Eaglevision magazine, and probably handle the 40 grain, but I don't think it would handle a 44 grain slug. The second reason is I don't feel the need to push the gun that hard just to have slightly better performance than the 36 grain slugs. The third reason is cost, which is why I shoot the NSA 31.2 grain more than any other slug. I only use the 36 grain for hunting, but the 31.2 performs well enough to accomplish almost any task. Now, if I were shooting in competition, where every little bit matters, I would probably be looking at lot harder at the 40+ grain slugs. I wonder if the 44 grain would require a bit faster twist than the Superior Heavy offers. It is possible that the 800mm may have a slightly faster twist, but that's just speculation on my part. The previous Slug A did go as fast as 15-15.5 twist though...

Those are just my reasons, but they may not be the same for other people. I can certainly see the benefit of the higher BC 40+ grain slugs, but the price would have to change for me to make that move for anything, other than hunting. Just looking at many of the BC numbers out there, it would seem the BC advantage goes to the .22 slugs over the .25 in most cases. I guess it just depends on intended use, and which tradeoffs matter the least to each person
