We use EDM because it can make each and every baffle and the end cap of the silencer concentric to the rifle's bore to as close as 0.0002 of an inch. That is just not possible with normal machining no matter if the can is welded or not. A long/thin reamer cannot make a straight cut without moving when in contact with each surface. And if a can is not welded, the baffles will move within the can a far greater amount than that.
Yes, it is extremely expensive but we feel it is worth it if you want the best. EDM shop time is in the $50 to $120 an hour range depending on how fast and modern or precise the machine is. Most are $90 an hour or so. A can takes quite a long time on the machine.
