Good Morning All
I recently picked up 100+ used 5.56 x 45 cartridges (S and B Headstamped) on my local range
I realise that the spec. for these and .223 Remington are not quite the same and there seems to be conflicting info. on the internet as to whether they are safe to reload and fire in a .223 or not
Should I just dump them or try a few checking for signs of pressure as usual?
What do you all think?
