love my 7x57. I shortened my bbl. to 20" to make it handier in the woods or a box blind. I normally use it on deer and hogs, it does a bang up job. With a modern action and good brass I load mine a little hotter than the book, but it really shoots better that way. For game my favorite bullet is the Sierra 150 gr. GameKing. I've taken deer with all the bullets available between 139 gr. and 154 gr. and settled on the 150 GameKing as my favorite. I've been hunting with that same 7x57 for almost 40 years.
My rifle started life as a Mark X Cavalier. It's since been restocked and reblued with a matte finish and a classic hand checkered AA fancy walnut stock with a satin finish. With a Leupold 2-6x scope it is truly a little sweetheart.
