Only if the tape is very narrow width. You don't want to get past the internal case web "floor". The o-rings will last a while and also tend to press the base of the case against the bolt face, which won't happen with tape.

Additionally, I could see where tape would be easily scrubbed off during chambering, leading to off-centered cases as well as sticky debris in a fairly inaccessible area. Could potentially lead to partial bore obstructions, etc.

Sorry for the slow response. Bad sick for a day. Ugggh...
