[QUOTE="Rardoin, post: 2199122, member: 114954"] For a no turn neck shooting 180 Hybrids the standard is .320" neck/.225-.250" freebore. My .284 no turn reamer has .225" freebore for the 180/184 Hybrids but, if I were to have it reground, I would go with a .250" freebore so I could have the base of the bullet a closer to the base of the neck. For a hunting gun I would go .225" so you could still run shorter bullets and have plenty of bearing surface in the neck. A friend of mine just measured a new Lapua .284 case with a 180 hybrid seated and the loaded neck diameter was .315"; this gives 0.005" total clearance which is perfect for the .284 Win. [/QUOTE]
