The little gun that can. Trying to setup the Air Venturi to shoot slugs 

I can second that on the 0.2160” diameter being ideal in an avenger barrel. Most slugs I’ve bought are a little smaller diameter, 0.005”, than what’s listed on the box, except for the FX hybrids. If it says 0.2170”, then it is exactly that. I’ve had great groups with pellets, of course, but the NSA 17.5 and 23 gr 0.2160 slugs did the best. My calipers measure them as 0.2155”-0.2160”.

Try AVS slugs, they have mang different diameters and weights

I don't think slugs are necessary for anything inside of 100yards. Most people are just following a fad they saw someone on RU-vid doing.

@@heithwatkins yes and no, the majority are doing exactly what you're saying. I myself use slugs for downrange dump at long distances, but I also look for slugs that can maintain precision but expand really really well. I pest around homes mainly and golf courses. Shooting pellets 9/10 times results in pass throughs even with vital shots. I shoot iguanas in south florida.

@@heithwatkins I got the gun to shoot slugs for long range on coyote at night. BC is better with slugs and less wind drift. It's not a fad.

My maverick loves the Zan 33 grain , Jsb knockouts Mk1 & 2, Apolo 33 grain (really cheap! :). Reg at 135 bar, hammerspring powersetting 4, turn fineadjustment screw out aprox 4,5 . mm. Try and get to a speed of about 995 fps. One inch groups at 100 meters (not yards) for me.

WIll do, I have a lot of pellet testing to do with this gun

Wow that is very high on the regulator. Unfortunately the Nielsen slugs are rediculously expensive in South Africa, almost 300% more expensive, thus not a viable option, not even to test as the price doesn't warrent it. I did some H&N pellet testing the weekend, the gun loved them as well, busy editing video.

@@AimSmall Thanks for the reply Gert. But strange that the NSA's are that expensive in SA, here in the Netherlands you get a box of 400 17.5 grain NSA slugs for 22 Euro's, about 390 Rand. On the other hand, the SA Patriot Javelin slugs are ridiculously expensive over here! 25 Euro's or 440 Rand for 200. But then again, something has to pay for Matt Dubber 's increasing waistline.... Sorry, bad case of Dutch humor over here. I like Matt and what he has done for airgunning in general. I haven't found any other manufacturer though who produces really light .22 slugs. I've been contemplating getting a power upgrade kit for the gun (plenum, hammerspring etc), but that will set me back 150 USD plus shipping. That's more than a third of the price of the rifle..... Nah.

@@mxmbob Whahaha, also noticed Matts waistline expansion, married life is good to him. Yes NSA slugs are R440 for 100 (about 25Euros - but only 100 slugs) versus JSB KO's at R190 for 200 , or ZAN for R250.

@@AimSmall Those are ridiculous prices indeed! I wasn't aware that NSA made platinum slugs for the African market .... We pay about the same for those other two slugs. But shooting slugs is not very big in Holland, since hunting with an air rifle is an absolute no-no. We've got no power or caliber restrictions whatsoever , anyone over 18 can go to a gunshop and buy a 1500 ft-lb .72 Zeus big bore (so that is baie lekker), but even for pestcontrol you need a license, and those are hard to obtain. Anyway, I can't wait until the FX Halo ammunitions will be available. I have high hopes, and maybe they will be reasonably priced.....

Great work to get that tune sorted. I still need to do some serious work.

@@AimSmall (admittedly that was still a lot slower than usual slug speeds)

Great, thanks, will try 217's and 216's, maybe the 218's are to fat for this barrel. Tx for the heads-up

Whahaha. thanks Roy. Life is a lot simpler and cheaper in sub 12 guns...

What was your hammer, reg, and fpe? I had no luck with the .216. Thanks

@@rasberryrl my reg was around 150 bar .... the hammer spiring was maxed .... shooting 17.5 gr at 930-935 fps ..... heep in mind that you have to find the max spot ! If you toght all the way the velocity will drop.

Whahaha, they are not bad with my own blend of 22gr slugs at 830fps and 950fps (but this takes a lot of air)

Yes it is an option, but for lighter slugs only.

NO. The gun has a sweet spot where the hammer spring and reg meets, if you increase the reg to much your shot counts drops and you waste a lot of air, I did push mine up to 2600 psi but the gun didn't like it. It can handle that pressure but it didn't sound good, plus no silencer could stop the loud bark it gave, I would p[refer shooting it at 2000 psi max. Mine is actually lower than that at about 1500 psi.

@@AimSmall I'm planning to make 26ftlb out of it using 14 grain slug, so

@@mathewm7157 You can do that easily with the reg at 140bar and 600mm or 700mm barrel.

@@AimSmall which barrel can be swapped on an Avenger? Will it be possible on the original barrel? Also will using the reg at 140 bar affect its life ?

@@mathewm7157 Don't know about barrel swops, there is no after market custom barrels, you will have to get one made up for you. Regarding the reg at 140bar, go for it , they are build to easily work up t 170bar, thus i won't effect barrel life or parts.

Indeed I do, they are gonna be very slow.

@@AimSmall yes they do like about 950fps to be happy.
