I happen to have a small "stock"of bullets for both, but I highly recommend,especially owners of the older 9.3s,a sufficient stock of bullets be "laid by".Don't be concerened if slugging your 9.3 barrel shows a groove diameter of less than the bullet's .366" dia.(even as small as .352").These 9.3 bullets are specially made to be useful in smaller barrels, without driving pressures up excessively.Vol423 is owed a debt of gratitude for doing this.
