.223; .308; .366 for me. Default .308 for hogs and deer. If smaller cartridge wanted - jump down to .223. if bigger wanted (in Europe never needed) jump up .366.
In the past I have been cutting things much closer - .223; .243; .284; .308; .323; .366; .458. Drove me nuts. For noticeable difference in on game performance (same bullet type) I have cut back to the three mentioned above - and the major factor to me is indeed blood trails. For hogs no sub .308 cal. for me anymore - mind, in Europe wild boar are an indigenous game species and not classed as feral, so animals are actually followed up with dogs on sub par shots and a blood trail helps.
