It was a great idea as a caliber, but introduced at the absolute worst time. In reality, it's a hot-rod version of the .38-55.
I bought a 94 Big Bore in .375 Winchester not long after it came out. It was a beautiful rifle and nice and light for its caliber...but that was the problem. I traded it (I regret it, one of the few I got rid of) because I felt it stomped me too hard.
I think that rifle has killed it's share of bears- I haven't shot talked to its owner now in several years.
I have seen the Marlin versions, but no experience with them. The notations on the Marlins, is I am certain that they have to be all micro-groove and over-sized cast bullets are the order of the day (if you want to use cast bullets).
