I think Muley might be on to something. Shooting a RB in a 1-28 twist can be something akin to fun as it spins the dang ball so fast - irregularities in the make of the ball really show up.

For Rondy events I am using a 1-48 twist Renegade and have dropped the powder to 60 grains and it works great. With a 1-28 I would think it would take an even further reduction...

But of all things do not go by me.... I am far from being or possessing a lot of information about shooting PRB's...
