The 57-year-old airline pilot gave evidence about his version of events about four weeks into the trial.
Lynn has pleaded not guilty to two counts of murder over the deaths of Russell Hill and Carol Clay in Victoria's alpine region in March 2020.
He claimed their deaths were accidental and admitted to the "despicable" act of moving and burning their bodies.
He told the jury, and police during his interview, that Mrs Clay died during a struggle with Mr Hill over Lynn's gun where a shot discharged and went into her head.

Lynn said Mr Hill died in a second struggle with a knife.
Jurors retired to begin deliberating on their verdict on Friday afternoon.
They returned to the Supreme Court on Wednesday with a question about video evidence of Lynn and another witness, police ballistics expert Senior Constable Paul Griffiths.
"Could we please receive the recording of Mr Griffiths' evidence and also Mr Lynn's evidence on the stand? Can we please receive this in the jury room?" Justice Michael Croucher said, reading the jury's note.
He agreed to allow them access to videos of the live stream, which he said were each about two-and-a-half hours long.
However, he said it could take the court until the end of Wednesday to edit the videos before they were given to them.
"You will see it in three files on a USB. Apparently it's taking some time to download because it's big, because of the nature of the recording," Justice Croucher told the jury.Â
"But it'll be with you pretty shortly so you'll be able to play that in the jury room at your leisure."
He reminded the jury of his directions to them on Thursday and Friday, including that Lynn is presumed innocent and the onus was on the prosecution to prove he was guilty of the murders.
The judge also reminded them of his directions about prosecutor Daniel Porceddu's final address, where he said Lynn and Sen Const Griffiths were not given the opportunity to respond to matters that he raised.
He directed them to more readily reject Mr Porceddu's theories that were not cross-examined, and more readily accept evidence from Lynn and the police expert on the stand.
Justice Croucher sent the jurors away to continue to deliberate.
