Anyone who want's more margin on short option trades than his broker will give him is begging to get blown up. Be prepared to have to sell your house when the bill comes in.
I'm not suggesting being stupid. A limited risk position, at least by the end of the day, is the only sensible one to end with. Even more sensible is to be positioned with distal long gamma. Your position still ends up short gamma/vega.
To the point challenged, however, leveraging to a greater extent than Reg T is one way to make possible the returns mentioned (~ 15%), and all without being irresponsible. Of course, the leverage issue is not the important point. A talented eye towards position management is the sine qua non. There are other nuances such as skew, efficient capital use, model imprecision- all have their exploitable features under the right conditions - but these are irrelevant without proper position management. My congrats to SIV66.
