If you are talking about brass tubes the way I do it is take a sharp xacto knife blade and then roll the tube on a table with the knife gently press down on it. after a few rolls you will get through the brass. You may need to file the end to get rid of burrs

The easiest way I have found to cut steel tubing is to take some tamiya tape and wrap it around the tubing so that the middle of the tape is about where you want to cut, then take a Dremel motor tool and use the high speed cutting wheel to cut it. This generates quite a lot of heat so I hold the tubing with pliers.

The Tape keeps the part from flying off into the abyss .

Once the part is cut, you can then use the end of the dremel cutter disk to polish and even form the end of the barrel.

Anyway - that's what I do.

I tried the technique of rolling the brass tube under an Xacto blade, but I didn't find it satisfactory. It cut through eventually, but ruined the blade completely and the resultant cut was quite rough. Maybe I'll try the Dremel approach next time.

I have one of the tube cutters, the only drawback is that you can't crank it down to cut the really small diameter tubes. For the 1/48 chainguns I recently made, I used a pair of my sprue cutters and a round file to open the end up again. Whichever end was the best, became the muzzle end and the other end was the breech end.

The tube cutter is nice to have, though...
