Wasn't sure where to post this, but since I have no experience with gain twist barrels I figured this might be a stupid question. Would the .224 Valkyrie benefit from this type of rifling? Some google searching lead me to youtube video of a gunsmith working with Bartlein to develop a 20" service rifle barrel that starts at 1:13" and transitions to 1:6.5". In the video he claims they were able to relieve pressure while still stabilizing the heavier projectiles. Given the issues with blown primers and and the accuracy issues with 90gr SMKs, would this be a potential solution?
