Re: SS109 in 223 chambers
That can be an interesting question, twist rates.
Depends on the quality of the barrel, Savage 9 twist, Winchester 9 twist, and Bushmaster 9 twists all stabilize the 62 grain mil, even the tracers. Remington PSS 9 did not, 700 Varmit would not either.
Good luck on accuracy on the mil ball too, it sucks. We don't get great accuracy with SMG's at 25 yards with it.
Chambers, the stuff is hot ammo. A Saami 223 chamber and the military chamber are close enugh to work OK, but stay away from tight match chambers with tight throats. I bent a bolt retaining pin in one built AR-15 with that ammo and a match grade chamber. Gunsmith told me I was lucky not to have sheared off bolt lugs.
