He was also accused adjusting his aim after the first bullet was fired and she fell backwards inside the toilet cubicle.
The athlete is spending a sixth day on the witness stand, with prosecutor Gerrie Nel, known as the 'bull terrier' in legal circles, continuing his relentless cross-examination.
Pistorius also faces gun-related charges for two separate shooting incidents, one from a moving vehicle and another at a busy northern Johannesburg restaurant.
The 27-year-old further faces a charge of illegal possession of ammunition.
He pleaded not guilty to all charges on the first day of his hearing on 3 March.

Nel accused Pistorius of changing the heart of his defence while giving evidence in court and pushed him on every detail surrounding the deadly shooting.
"So I went back to the bathroom as quick as I could. When I got back to the entrance of the bathroom, I started screaming out for her [Steenkamp]. I was scared of entering the bathroom again," the 'Blade Runner' told the Pretoria court on Monday.
The prosecutor questioned Pistorius on why he immediately thought Steenkamp was in the toilet cubicle once the shooting was over.
"You see, Mr Pistorius, that's your version and you have to build it as you go [along]. Why would you check curtains but not the [bedroom] door? That is a question. Why would you not think she left the bedroom," Nel asked.
"The curtains were on the way to the bathroom," the athlete responded.
Nel also returned to the issue of intent, asking Pistorius who was to blame for the shooting.
"I blame myself," he responded. "I blame myself for taking Reeva's life."
Nel introduced more details of the state's case against the athlete on Monday, revealing an accusation that Pistorius knew exactly where his girlfriend was when he opened fire.
The sportsman said in hindsight, the noise he heard that prompted him to open fire was the magazine rack being moved inside the toilet cubicle.
But the state countered, saying that while Pistorius can remember hearing that noise, it was in fact after he had fired the first shot through the door, which hit the model in the hip.
Nel says when Steenkamp collapsed backwards onto the magazine rack, the athlete adjusted his aim and fired the final three shots, killing her.
Pistorius insisted that he believed there was an intruder inside the toilet, but that he never intended to shoot anyone.
Earlier on Monday, he told the court he screamed at the intruder to get out of his house, but conceded that he never gave anyone a chance to exit the toilet.
He said he did not remember hearing the door being locked, suggesting that it happened at the same time that it was slammed shut.
The matter has been adjourned and will resume in the North Gauteng High Court on Tuesday morning.
