Bill, Based on bad experience with someone else's bushing job, I recommend the following two things be insured. Be sure the cartridge case neck extends past the joint, so that obturation keeps high pressure gasses out of the joint. The second is to pull the bush into the barrel with a rod threaded on both ends with nuts and washers to keep everything tight until the glue sets or the solder cools. Bushes, pins, dowels etc. are pretty bad to back out of holes while waiting for glue to set/solder to cool; whether due to taper, trapped air, pressure from expanding gas; movement must be guarded against.
