BlkHawk73, don't think the 7x57 needs selling to those who understand it ... or to those who need to be sold. As any other cartridge if you use it well, you'll sell yourself on it.
Seemed to kill as well for Eleanor O'Connor as it did for the Spaniards on San Juan Hill and the Boers. Still seems to do so, as JB points out. The more things change they more they stay the same.
Unless it's a a J. Rigby 275 in a bolt, it's hard to get more classical than a Ruger No. 1 in 7x57.
