Narrative:

Flight to T82 (gillespie county); VFR at 6;500 ft with VFR flight following until houston center could no longer provide radar coverage as we descended through 3;500 MSL. [We were] approximately 8 miles out at this point. Changed to CTAF (122.7) and reset transponder to VFR. Runway in use at T82 was 32 (left traffic) as we are approaching from due west began to report position and intentions to cross midfield for a left downwind 32. Repeated position and intentions at 5 miles; 2 miles and then reported crossing mid field. Other traffic [was] also reporting positions; with one entry on a 45 from the northwest which we had a visual on approximately 2 miles distant. Reported left downwind 32 full stop; then reported left base 32. As we started our turn to final; a large white twin engine aircraft crossed just below us; I noted no strobes; though I was in the process of announcing a go-around and configuring the aircraft full power; flaps up; etc.; so perhaps I missed many details. I and my passenger pilot never heard any position report from this aircraft; nor did we even see it until the event. After the event no communication was heard from the twin; nor did it call clear of 32 as it went onto the ramp. After the go around we returned to land without further complication. The twin was nowhere to be found; and may have gone to hangars on the north of the field. I thought it best to avoid a confrontation; so I did not seek out the other party. We did do a search on an internet site and discovered the aircraft was on an IFR flight plan; and appears to have shot an approach into T82 in VFR conditions ignoring the VFR traffic in the pattern at this busy GA airport; a popular lunchtime destination. A complicating factor; which is in my opinion a serious safety issue; is that erv shares the CTAF of 122.7 with T82. Erv is only 20 NM distant and radio traffic from this airport is loud and clear at T82 pattern altitude.
