I checked the clearance on my universal, which is set up for .38 Special, with a .357 case on the powder spount station. I only have about 1/64" of clearance from the top of the case to the "nut" section of the spount that is used to tighten it in place. Sounds like you may have one that has a wider section for the wrench when it is tightened in place....my only suggestion would be to replace the spout if you can find one that is "thinner"...does that make sense?
