IMHO: 1.You aren't going to find many for sale because the 358 never caught on and their weren't that many 358 Winchesters made. 2. The people who actually own and hunt with them are not likely to sell them because they kill like the hammer of Thor on deer and hogs. They do it with out deafening or kicking the hunter so hard that he misses . With standard cup and core bullets penetration is great! I would be perfectly happy to hunt every thing in North America with a 358.
