Narrative:

While proceeding inbound to the VOR on the 330 degree right, we heard ATC call our aircraft as traffic to an inbound twin turbo propeller belonging to a major airline. The safety pilot began looking for the aircraft, and when he spotted it approaching from the rear, took the aircraft from me and executed a steep turn away from the approaching twin. At the same time, pilot of the twin began complaining that our aircraft was too high, and too close, and wanted to file a near miss report. The twin was cleared to cross boulder VOR at 6500'. The controller said that he was indicating 6300' on his transponder altitude readout. Our pressure altimeter and transponder showed our aircraft at 6100' before starting the turn away. This resulted in only 200' vertical sep with approximately 125' for INS uncertainty. The pilot of the twin was hostile and unapologetic, even after controller told him that he was too low, and was given a phone # to file his report. I was under a view limiting hood, so I never saw the twin. But the safety pilot said that it was at least 3/4 mi away when he took over and turned our aircraft away.

Title: PLT OF SMA UNDER HOOD ON TRAILING FLT HOLDING NEAR BLD VOR AT ASSIGNED 6000' MSL WAS OVERTAKEN BY SMT ACR WHOSE CAPT COMPLAINED ABOUT A NEAR MIDAIR AND STATED WOULD FILE A REPORT.

Narrative: WHILE PROCEEDING INBND TO THE VOR ON THE 330 DEG R, WE HEARD ATC CALL OUR ACFT AS TFC TO AN INBND TWIN TURBO PROP BELONGING TO A MAJOR AIRLINE. THE SAFETY PLT BEGAN LOOKING FOR THE ACFT, AND WHEN HE SPOTTED IT APCHING FROM THE REAR, TOOK THE ACFT FROM ME AND EXECUTED A STEEP TURN AWAY FROM THE APCHING TWIN. AT THE SAME TIME, PLT OF THE TWIN BEGAN COMPLAINING THAT OUR ACFT WAS TOO HIGH, AND TOO CLOSE, AND WANTED TO FILE A NEAR MISS RPT. THE TWIN WAS CLRED TO CROSS BOULDER VOR AT 6500'. THE CTLR SAID THAT HE WAS INDICATING 6300' ON HIS XPONDER ALT READOUT. OUR PRESSURE ALTIMETER AND XPONDER SHOWED OUR ACFT AT 6100' BEFORE STARTING THE TURN AWAY. THIS RESULTED IN ONLY 200' VERT SEP WITH APPROX 125' FOR INS UNCERTAINTY. THE PLT OF THE TWIN WAS HOSTILE AND UNAPOLOGETIC, EVEN AFTER CTLR TOLD HIM THAT HE WAS TOO LOW, AND WAS GIVEN A PHONE # TO FILE HIS RPT. I WAS UNDER A VIEW LIMITING HOOD, SO I NEVER SAW THE TWIN. BUT THE SAFETY PLT SAID THAT IT WAS AT LEAST 3/4 MI AWAY WHEN HE TOOK OVER AND TURNED OUR ACFT AWAY.
