The 8mm Mauser is adequate for all North American Big Game [properly loaded] But any of those 196-198 grain factory offerings are very effective on deer/moose/elk, etc. They expand reliably, and since they are most often European loadings, they have sufficient velocity to do the job properly. In Chronographing NA loads vs European loads, there are some interesting revelations. The Norma 196 grain loads and the Igman 198 grainers both are faster in my rifle than any North American made 150 or 170 grain load.
