[QUOTE="Bob Wright, post: 1549055, member: 104363"] Tight neck chambers require it if you cannot get a new bullet to slip into a spent case, easily, like it will slip in with gravity, lol. My custom barreled 7 mm Rem mag had a tighter neck without ordering it that way. Pressure signs caused me to exhaust a lot of inspections and at the advice of a really good gun builder, I casted the chamber and found my Nosler brass and the tight neck were one cause of my pressure issue. I ended up with .004 clearance of loaded neck size gave me a nice release and lower SD (7 fps SD) in this handload. It required about .0012 reduction in diameter on loaded cartridges if I remember correctly. It really reduced those Satanic flyers too. [/QUOTE]
