As of my last knowledge update in October 2023, Sports Academy does not typically sell firearms, including the Sig Sauer 556 Rifle. They focus primarily on sporting goods, athletic apparel, and outdoor equipment. For specific inventory inquiries, it's best to check their official website or contact their customer service directly.
556 = 55,600%
70% of 556 is 389.2. Which means that 166.8 is 30% of 556.
why you asking me 556-thousands = 556/1000 = 0.556 as a decimal
Yes there is a difference. They are physically the same size casing, but the 556 military rounds' chamber pressure is ~10,000 psi higher then 223. Military rifles generally have chambers with a different throat configuration than normal sport 223 rifles. This being said, I would not recommend shooting 556 unless your rifle was designed for the higher pressures.
