800 rounds and you won't be able to hit your azz with it! You can't stick that much powder into a case and blow it down the bore without throat erosion!! Get back to me when it 'goes' so I can say "I told ya so!"
I'm kinda thinkin that anyone building a rifle like this does not really give a big rats azz if he has to re-barrel at 500 - 800 rounds.
