Only two rifles from circumstance is a shame,
only two rifles by informed opinion, I can relate too.
Only two would be:
DWM 98 in .30-06
DWM 98 in .458 Win.
Only one would be:
DWM 98 in 9,3x64
Have taken Roe deer, fallow deer, wild boar and brown bear with this last one and am confident I could get all else done in hunting.
That said - I am happy for choices and find myself disagreeing with me all the time. My love for the Marlin .45-70 just bears that out.
