Hello , just a simple question : how much power could we expect from a FX Maverick in .30 cal with a tuning kit ?
Thanks.
Thanks.
FX Maverick .30

Depends a lot on the barrel length. It also depends on the "Tuning Kit" you choose. The Huma is different than the FX kit for example. But assuming you get a heavier hammer weight and hammer spring with no other mods through a 700mm barrel 110-125fpe. FX advertises the 700mm able to reach 116fpe with their slug power kit. A Huma pin probe and transfer port will give you some more speed too.

I'd say, what are you trying to do? Blast through a concrete wall or armor plating, both a fools errand, or take down a deer? No matter what you'll need to make sure the regs are up to it and in stock form they won't be. Mongoose covered the air poofing sided, you need to make sure you have the brass regulator rods, MATCHED heavy Bellevilles (a .53mm average will give you 117 to 170 bar), that's equal loading on all of them and for max power, the thickest you can get, buy a bunch, a hundred or so and start measuring the edges, then give all surfaces that touch a light polish. Use a real lubricant on them to help them slip and slide, silicon isn't a real lubricant btw, I recommend a good synthetic motor oil, it won't go boom. The reasoning behind matching the washers, the lighter ones will do all of the work, with them matched they're going to be equally loaded so your consistency should be, well, consistent. A further note you will kill the rods fast with more pressure on them, that delrin insert can only handle so much, and you can only polish them down so far. So...buy some spares. I'm pretty sure that Huma uses the same system so it may or may not matter in the long run YMMV.

My advice is go at least 600 mm barrel and just use it first in stock format before putting all the power upgrades in. They produce a lot of power stock in .30. They already out of the box have a heavier hammer weight than the other calibers.

The cheapest route to big power in .30 is to run two plenum tubes, deleting the second reg.

FX Maverick 160cc plenum
Ernest Rowe has an FX Maverick that he has removed the 2nd regulator and plenum tube from and replaced the 2nd regulator tube with just a hollow tube. So there is only 1 regulator (the 1st reg next to the bottle tank) and everything from there back to the valve is all one big plenum (160cc)...

Thanks for your answer . I'm not a hunter but there are a lot of wild hogs in the neighborhood , doing some serious damages in the gardens . I don't know if .30 cal is needed to kill them neatly . Maybe a head shot with .25 at 30 yards would be enough . I just want to be sure to kill them as quickly as possible .

There are reports in the Hunting Forum about hogs, I'm pretty sure they used .30, I sort of remember one with a .25. My Raptor is chucking 49.2 gr slugs out at 880fps, 30.2gr's at 1080, that'll leave a mark. I forget what speeds I'm getting out of my Maverick 600 with the 30.2's but it's pushing 1,000fps.

Maverick sniper 700 mm heavy liner, huma-air slug power kit, hammer 26.4 grams, Bulgarian slugs made by friend 55 grain , speed 290m/s or 951 fps, regs 195/165 bar. Good settings for 150 joules.

I think this will depend on the size of hogs you have over there in your part of the world. Here in the US we get them over 200lbs pretty regularly, with the smaller sows being more like 60-80lbs. I know some of the European "hogs" are more like our piglets and wont need nearly as much fpe.

Yes that's the case here in Europe , around 70-100lbs . Smaller country .....smaller hogs
