My two cents is that unless you have to meet some silly caliber or case shape restrictions or are planning on going after the big bears or big African game, you don’t need anything else to get the job done. However, if a bigger hole in the barrel will give you greater peace of mind, then you can’t go wrong with the .30-06. As stated above, over 100 years and many battles have proven the effectiveness and cartridges can be found literally everywhere that cartridges are sold.
