re: Army Chooses Sig 6.8 mm Next Gen to replace the M4 carbine and M249 Squad Auto

Haven’t seen anyone talk about barrel twist. That is probably the big difference between 5.56(which is great round) and the new 6.8. One on the real factors in long range is barrel twist which I believe is 1-9 for 5.56 and will probably be 1-8 for the new 6.8. The problem with the 5.56 barrel twist not being fast enough is the bullet will begin to wobble after 3-400 yards greatly affecting accuracy. To compound that with the 5.56 in 55 gr not having a great Ballistic coefficient the bullet will be heavily susceptible to drift. The .224 Wyld adresses all these issues. To get an extra couple of hundred yards out really would have required a new cartridge. I’m positive there will be AR uppers out for the new cartridge as soon as SAAMI info is available which will be bad arse. I think the current AR platform is hard to beat but when u spend other peoples money Sig does make some really cool shite.
