I got the heym models switched up in my head, and thought the one you where after had a jäger lock, since not the 30r blaser are out of the question for me to. I agree with you to a certain degree on the philosophy of double rifles with heavy bullets in moderate velocities, but I just tried an Austrian made double (can`t remember the name though) in 7*65r and fell in love with it. It handled great, and felt so light and nimble, almost like a kipplauf. But 375 flanged ain`t a bad choice either.
