Care to edit that?? hehe6mm Rem loads may not shoot well in rifles marked .224
The 6mm uses a 1/9 twist. The 244 uses a 1/12. The 243 uses a 1/10.The biggest issue with 6MM Remington was the slow twist designed for lighter varmint bullets/shooting varmints, but people tried the m for hunting and found them wanting (Duh). The .243 Winchester, while a near ballistic twin, had a faster twist and proved a good hunting caliber. The .243 caught on, the 6 Rem died out, except for varmint hunters who liked it.
