Deciding the best ammunition to use? Can be tough but let's find out? Hey, trying to fin out what the best in your opinion of course is the best 22 WMR ammunition? I use both the 45 grain CCI Maxi mag HP and hornadys 30 grain VMAX both at stellar ammo I push between the two the hornady. What's you opinion and what do you most offer use for beat result. Take in mind the game you generally hunt.
