Wonder how these TNT bullets would hold up in a 9 twist 223?
The 55s were okay but these would be scooting a goodly bit faster.
Pretty decent I think if you have a smooth barrel & gas port. Don't think as bad as a 1 in 8 or 1 in 7.
In 1 in 7 twist a lot rifles will make vapor trails all the way to the 100 yrd line, but so will a blitz.
