Problem is you are guessing on a choke brand. A choke butts up against a ledge cut into the barrel and it is important the edge of the choke doesn’t protrude above the ledge. If so, as the wad and shot travel down the barrel they will catch on the edge of the choke. Which acts as a partial barrel obstruction.
The result can be a choke edge that will be bent into the barrel…or possibly blow thru the barrel end.
Most inside barrel diameters for chokes are measured at the end. If your barrel has been cut then the choke may have been special made for the diameter we’re it was cut.
The dimensions are even more critical for thin wall chokes.
And, I’ve have seen factory chokes out of spec for a particular shotgun be out of spec and rupture. Or perhaps they were not seated completely.
Best option, especially for a possibly cut barrel, is for someone like Briley to get it right.
