[QUOTE="VLD Pilot, post: 1958270, member: 103947"] Easy fix, run 80 ELDs. Getting into the 90s requires a 7 twist. Then RPMs get too fast and bullets will blow up. It's a fine line. The big case .224s cause the problem. If your in higher elevation (4000+) an 8 twist may work fine. Even going to a AI or CM, velocity will be better but the bullet weight won't be unless getting into a faster twist. I have some buddies that had 7 twist barrels with a 22-250 AI and bullets were exploding consistently. 80,88 and 90s were all having problems. The 8 twist is about the best IMO and the more elevation (altitude) the better. [/QUOTE]
