Rimrock bullets in Montana offers 12 & 15 BHN hardnesses in their standard line for certain applications. Haven't bought any yet, but getting ready to do so, soon. The bullet company I used previously (Velocity bullet co.) seems to have joined up with them. They were on the "hardcast" bandwagon also, but I never really had any probs. Much is made of bullet obturation, but bullet fit (size) and velocity are the important factors, IMO.
