my understanding is .686, .685 .684 and then smaller will be available to paint.
However any size below .680 will require the o-ring removed from the bolt and that will effect shell ejection.
Also as this is primarily a First Strike Platform, the .684 , .685 and .686 sizers are the best sizes for the size variations of First Strike rounds so hose would be the included shell sizes.
Beyond that Bill will have to chime in with his info.
