I have a line on a sportered Winchester p14 which is still in its original 303 British chambering. It could serve as a "truck" gun, but I am wondering what potential it has as the base for a build. I am led to understand that the p14 is pretty much a p17, but in 303 Brit instead of 30-06. Does it have the same possibilities for a build as a p17 ? Seems to me I've seen discussions about the p17 serving as a base for cartridges such as the 375 H&H, 416 Rigby. What's possible for the p14, and what makes sense for it? Does it merit the required investment for any sort of build at all?
