Vol423,
Z&B still makes this bullet( although I've heard in .366), but I'm not sure of the avalibility of bullets in the US. Z&B ammo is avaliable. This bullet is especially adapted for use in barrels with varying diameters, so don't worry that it is .366"dia,(if it is).Cast bullets would liberate you from dependence on other people.There are also manufactures that make "soft",about 200 gr., bullets for the 9.3x72R.These bullets are not the "express"style for differing barrel diameters,but can be sized to the diameter you need.If the bullet will not enter an unsized, but fired in the same chamber,case it should be resized.If you decide to use cast bullets, you would still have the 50 RWS bullets for hunting, which would last a long time. There is a three part article on loading 9.3x72R in "WAIDMANNSHEIL" from a couple years back.If you are not already a member,it would be good to join the German Gun Collectors Assn.
