I'll second Mr. Sisk's vote for the 8x57. That used to be the kids rifle cartridge of choice in our camp. Most of the founders were gun guys that had at least one loner 98 so chambered. I used one to take my first deer. These days it seems the guys that own 8mms are all at least in their 50s, bought them 25 years ago when 98s were pretty cheap, and shoot them once or twice every five years. I have to admit I kind of fall into that category.
