224 Valkyrie - 6.5 vs 7 Twist Head-To-Head Range Test
This head-to-head range test compares 1:7 and 1:6.5 twist barrels for the .224 Valkyrie cartridge using heavy projectiles. Contrary to common assumptions, the 1:7 twist barrel demonstrated surprising stability with the 95gr Sierra MatchKing and 90gr SMK, even outperforming the 1:6.5 twist in some instances. The test also highlighted issues with brass longevity and primer pocket looseness at high pressures.
