With the coming of Summer, hunting possibilities change, typically for the better. Prairie dogs, ground squirrels, and gophers are all fair game. And so are pigeons, Eurasian doves, and house sparrows. Oh goody!

Is the FX Impact M3 State-of-the-art and king of airguns?

Oh man, I've gone down the rabbit hole of watching FX Impact MK3 videos. My mind is whirling. Also have a shopping cart loaded with Impact MK3 .25 Sniper, along with a slug barrel. FX recommends a slug kit that comes with a pointy pellet probe.

Now I'm backtracking on to whether a standard length Impact would better suit me with my gimpy shoulder. Of course the shoulder will heal up and I wonder if I'll regret not getting the sniper setup.

I suppose I can always swap out barrel and shroud on down the road.

One of the big selling points is the ability to take someone else's "tune", with a slug or pellet, make that your settings and be very close to the performance of that someone's Impact. Apparently anyone can tune their Impact MK3 now.

Of course after having taken apart all my airguns at one point or another to reseal them, I wonder how complex the task is for an MK3. Are mere mortals able to do this? If not what is a reseal job gonna run?

Oh the questions. Gonna call Utah folks later today.

I've probably done more research on the Impact, than you have. So here's a few of my suggestions.

First thing is to decide how much power you want to generate. You can get the Impact Mk III up to about 100 FPE. But, you will certainly need the longer barrel, and the heavy-slug probe to get there. You will also need the Superior liner to boot.

The regular liner which comes with the gun will handle both slugs and pellets up to about 30 grains. The twist (as I recall) is 1:23. The superior liner is 1:17. If you go with the superior liner, you can easily shoot both (heavier) pellets and slugs. While pellets are a bit less costly, once you get the superior liner, and see what it can do with slugs, you'll never go back to pellets!

Whatever barrel you decide on, spend the $100 and get the carbon fiber sleeve. It does improve accuracy. But you don't need the longer barrel, unless you need over about 65 FPE. You can still get there with the shorter barrel, but you use more air and have a louder report. Just for the record, I do have the Impact Mk II set at almost 70 FPE, and it has the 600 mm barrel, and a standard probe!

By all means, buy the better DonnyFL suppressor. I paid for the upgrade, and ask for the Ronin, and that is what I got. There is a longer, smaller diameter unit, but it is a more money, and makes the rifle a bit too long in my opinion.

I'll remind you how overall length can be a mess out in the field. And, you told me you didn't like the weight either. So, do you want another pound or two, just to carry around when 90% of the time you don't need the extra length?

It has taken me several weeks to get used to the Element FFP scope I bought with the Impact (6x24x50). I find that at 10 power the reticle is easy to see, if not a bit small. But as you use it, the numbers don't mean much if you're into holdover as I am. Once you know the distance, the rest is memory.

What ever YOU decide, should be based on how YOU plan on using the Impact. For me, the average game doesn't often get over 15 pounds. But when and if a coyote shows up, he's dead meat out to about 125 yards.

I have a Hill EC-3000 compressor. If you're a fellow Guild member, and you pass through Roswell, NM, I'll fill your tank as a courtesy (4,250 PSI limit).

Realistically, whatever slug or pellet you end up using, you will tune in the 900's.... Therefore, what the longer barrel really buys you is the ability to fling longer, heavier slugs, with (maybe) a slightly better BC.... It all boils down to how much power you need to deliver downrange.... At 950 fps, multiply the weight of the slug times 2 to get the FPE.... A 34 gr. pellet (or slug) works out to 68 FPE, and a 50 gr. slug ends up at 100 FPE.... A 600mm barrel is 23.6" and a 700mm is 27.6", so the difference is just 4", but at the same pressure and efficiency you will get up to 17% higher FPE (and be able to shoot a 40 gr. slug at the same velocity as a 34 gr. in the shorter barrel).... I am assuming the "sniper" variant is 700mm?....

A few more items.

Bob is correct. The standard is 600 mm.

A replacement 580 cc tank will be available for the Mk III after the first of the year. I do plan on getting one, as the difference is weight is only a few ounces. It also means I can get about 110 rounds before I have to refill. Right now, I'm getting about 92. Just this morning, I went through 80 rounds before I called it a morning.

The 500 mm barrel can't use a longer tank unless you want to run without a suppressor, hence the 380 cc tank it comes with.

The 700 mm barrel will obviously do what Bob says it will. But is wieldy in my opinion, and a hindrance if you get in and out of your vehicle a lot like I do. This is also the reason I don't have the longer suppressor.

If you found out later you goofed, you can always buy a longer of shorter barrel and shroud.

Lastly.... Welcome to the fold.

As I muddle about, deep in contemplation, i pickup my one other bullpup, the Benjamin Bulldog. Tain't light at 7.7pounds even with a compact scope. With no moderator it is right at 36". Though not light it does shoulder easily and I can carry all day without too much muss or fuss. A sling helps.

An FX Impact Sniper without moderator is 39". That's still a good ten inches shorter than the FX Streamline. M3 Sniper weighs 7.35 lbs naked, M3 Standard is a hair lighter at 6.85 lbs.

Chewing furiously!
