I have a real barrels for both of my Impacts. Only one of them still has it on. The other I went back to the FX stuff because the gun is a .22, 500mm, and shot good enough without being a porker. Which is what it became with a real barrel. My .25 Impact still has a real barrel on it. But in order for it to shoot well, I had to balance a lot of things that are quite tricky. You have to find a slug the barrel likes, a speed it wants to be shot all the while making a chamber that suits that slug. I played with the chamber or leade quite a few times. Each time is a trip to the lathe. Once I got the consistency I wanted I had to go back to speed testing. If I sell the gun I will tell the buyer, here’s your gun and here’s the slug you must shoot. That’s probably a very good reason your $2k gun doesn’t come with a real barrel. The benefits are no more searching for accuracy nodes. Just get the slug out the barrel and not waste any air and it shoots. If there is such thing as a broad slug weight friendly leade, I have never been able to find it. With any of the barrels I’ve built. But FX found it with their little metal tubes. No leade necessary. The trade off? You deal with a lot of pieces all screwed together.
