GREAT snag there! I have had several MAuser rifles that I had 9.3 plans for. Like you,mine kept going to the bottom of the projects to do barrel.
Then, I became the proud owner of a CZ so chambered. Great gun in every way. I am happy for a few days, then start asking myself "On what am I going to use this, that my 340 Wildcat or my 416 Rigby is not going to be a better choice (I know, I know, turn in my rifle looney card) but during the dark days wherin I owned this, have a bunch of money tided up in something that I really dod not NEED was not somethiing I could allow myself.
So now, I find myself on the hunt for a Sabbatti SxS in 9.2x74. THAT 9.3 will be different enough to be worthwhile keeping. A decent powerful SxS rifle being a LONG standing itch for me.
