Long distance slug gun options

Check out his YT channel. He has his impact setup for 22 shooting 40 grain slugs at 22LR rimfire performance levels around 1000 fps and shoots past 100 yards. 

What prey are you hunting/pesting?

I suspect an FX M3 .25 caliber with a slug kit producing ~90 fpe will suffix for any small to medium-sized game you may be after. I have both the 600mm and the 700mm barrels for my M3 and I find the 600mm barrel to be more maneuverable than the longer 700mm barrel. And the FX Impact sporting the 600mm barrel does not give up much in velocity/power when compared to the 700mm barrel.

The modded .22 caliber Impact used by Matt Dubber is in deed a formidable weapon. Matt and other South Africans are restricted by law to air guns of .22 cal. maximum.

I purchased an FX Impact mk2 in .35 cal and replaced the .35 caliber kit with a .22 caliber kit. The power output is awesome, however, for energy levels of > 75 fpe, I prefer the .25 cal -- that's just me.

I can only speak for my impact mk2 25cal 700 barrel slug liner A, the nsa 36.2 slugs are perfect for the gun. The nsa slugs in general are the best, the 33-43gr slugs I have never went heavier than the 36.2 but many others have great results with the 38&43gr . The 36.2 do great from 850-950 but I mainly shoot them @870fps just so I can get more shots from a fill and still plenty of power. Hope that helps 

I would stick to .22 for slugs. 
I don’t think 25 cal has near the options for slugs. 

HI WHY NOT JUST GET THE URAGAN IN 30 TUNED?? I SHOOT 910 FPS 47 GR NSA@ 100 YDS & 200YDS LIKE YOU SAID NEVER OFF!! JUST FYI PAPERP

I would go with the 30 you have 25 and 22. But less ammo selection. I don't really care about price of ammo if it shoots good. For hunting I don't know. But 30 cal pops are loud. I like 22 cal to. Jsb is making a 30 knock out. Can't wait. 30 cal has a little kick. You need a moderator like a shogun .

I have a few model's of 30 caliber's, including an Impact modded to shoot heavy slugs fast. I've tried the .25 slug kit in it as well and have since went back to the .30 caliber configuration. The benefits of the .30 literally outweigh benefits of the .25 for me. For you, at the ranges you want to shoot, and with those tough prehistoric pests that you hunt in Florida, I would go with the 30 caliber.

As far as the .22 Impact goes, we owe a lot to those guy's down in South Africa (and in Sweden, and here as well) for what the Impact has evolved to in the .22 caliber over these past few years. However their species of pest is predominantly the pigeon and a medium sized varmint that die at the impact of the .217 caliber easily. The Hybrid slugs are phenomenal on birds and small rodents, as that is what they were designed for. Unless going with the heaviest grain of .217 slug, you will carry a lot better momentum and stopping power with the .30 caliber. The impact of a .30 caliber 47 grain FX Hybrid slug, or even heavier NSA slug offering would be my choice for the iguana at the ranges you want to shoot them at. Imagine the impact and transfer of energy of the .30 deep hollow point FX Hybrid at any speed; you won't have as many runner's or swimmer's!

Here's two charts to go over for the retained energy. One of a .25 in 38.5 grain and the other of the .30 in 50 grain. Both carrying the mail, but with obvious different B.C. numbers.

Thank you guys. Great advice and info. Although barrel length doesn’t have to be as short as possible, it would be nice if it didn’t matter. 
has anyone tested different lengths?

Barrel length definitely effects the potential power and speeds. Look at it this way, you can always de-tune a 700mm barrel, but a 600mm barrel limits it's top power. I have one pcp that I wish came with a longer barrel that I could de-tune if need be 

My 2 cents...

I own the Impact M3. I originally bought the 600mm but then "upgraded" to the 700mm

Both are equally accurate, some would argue the 600mm more so bc there is less POI shift. However the 700mm will give you another 20-30fps in velocity. You may want to do one of a few things to stiffen the barrel a little. I hear the barrel holder works well. Or you can torque the barrel using a 14x20mm CF shroud. 

600mm and 700mm both shoot slugs equally well in terms of accuracy.

As far as caliber goes just go with what you want bc everyone has a different opinion. I went with .25 and I love it. But some people say .30 bucks the wind more, however you will get less shot as well. All depends what is most important to you. I honestly think I would be happy with any caliber .22, .25 or .30

As far as a moderator goes, I think if the Sumo and Ronin are both great for the .25 and .30 (I went with the Ronin, bc why not, it looks amazing) BUT the Fat Boy with the muzzle brake is the sexiest as far as looks. And I BELIEVE it is actually quieter than the Ronin in FRONT of the gun, but a little louder from the behind the gun. Only a few dB's either way, you'll be fine with any of the above.

For hunting I would recommend a LCS sk19 and shoot slugs. Very accurate and powerful rifle. I'm a fx fan too but all my buddies have them and Sk19 shoots slugs better for us. And you have a quick follow up shot too. The gun hits like a hammer in 25 cal with big slugs.

I have shot my EvoL hps with 24 grain slugs out to 200 yards taking pigeons. 160-187 yards are pretty standard for me to shoot as well. No issues.

The 25 will buck the wind better with slugs I have a maverick in 25 shooting the 38.5 nsa slugs at 921 for 72fpe and that thing pops when it hits birds 50yds away and at 200 it's still got plenty of accuracy and power to kill a woodchuck even in the wind

对于狩猎，我会推荐 LCS sk19 并射击蛞蝓。非常准确和强大的步枪。我也是一个 fx 迷，但我所有的朋友都拥有它们，Sk19 为我们拍摄更好的蛞蝓。你也有一个快速的跟进镜头。这把枪像 25 卡的大锤子一样击打。

Great，which slug used on your sk19？
