Do you have a go to powder for .223 I've got varget and h-322 on hand so ill try those but if there is a " common great" powder out there ill try it too. I just gota remington sps tactical 1-9 twist and ordered some hornady 55gr vmax and hornady 68grbthp to try out any any pros or cons with these 2 bullets. Any other good or bad I should know for the gun or my reloading for it Thanks Guys
