The 300 and 375H&H had the same exact receiver and components, except for barrel (of course) and stock. There were different barrel contours for the 375H&H over the years and it also didn't have the sight boss. Well, they only made 10 with sight bosses, but it's likely you'll never see one of those in person. I like what the H&H receiver brings to the table, especially with my 338 win mag built on one. My 338 also feeds excellent: Smooth and effortless like it should, with absolutely no glitches of any kind. Let us know what you have in mind and some of the more knowledgeable guys can probably help.
