Honestly, at this point, I want more power, not less. My dream gun (that I cannot justify buying) is the 360DW Casull (a 353 Casull lengthened to accept 1.41" cartridges). At 48k psi using 200 grain pills, this is said to be a true thumper and it will still shoot 38 special light loads.
So... while a 327 sounds like a nifty trail gun, I think it is for the person already in to 32s with a load of H&R rounds already. I think this is sort of the same reason the 9x23 didn't make it and the 40 did... if you are wanting more power, you shoot a bigger bullet not just a faster one!
