A gentleman i know has offered to build me a precision rifle (for a fee of course) and said he could at a pinch do something in .303 British. I know it sounds a bit mad, but it would enable e to keep calibers minimized. Does anyone have data on the performance of 303 Brit vs 7.62 NATO over 200, 400, 500 + yards? I have to say I am quite intrigued by an updated 'T' rifle in 303.
