I really like the look of the 8x51 cartridge, as I do the 9x57. The whole catalog of Mauser cartridges is great and they look better in these Stoeger catalog drawings than they do in the flesh. I think a used gun seller could do worse than to have a letterhead or logo with these images of Mauser rifles and cartridges.

The 8x51 should be a fine cartridge for deer and even elk when loaded with the 196 grain bullet or modern equivalent and used at reasonable ranges.
