Thread: Reloading without neck sizing

Tight groups are always interesting, but I don't understand your set-up from your post. Chamber neck dimensions for 'no-turn' are usually around 0.004" more in diameter than across the neck of loaded brass, with significant expansion on firing that would have to be taken back down with sizing. The no neck sizing method requires very careful neck turning to get the clearance just so-so, and constant monitoring of the neck thickness from then on. Did you perhaps mean 'no neck size' tolerance ? What do you attribute the better groups to... what I mean is have you got a theory as to why minimum clearance necks are reducing groups ?
