I have a packrat friend who I keeps an eye out for firearms related things for me during his trading.  He came up with something real nice for me!  A complete and matching 1916 dated Norwegian Krag receiver!  So now I have this Austrian made .243 barrel, and a complete receiver to plug it into!  Not to mention a FP-NK receiver sight w/target knobs, a 1950s made stock blank, and a new old stock Lyman ramp front sight that fits the barrel.

Now the problem.  Should I have a .1" taken off the barrel stub and turn it into a 6mm Niemiller, thus precluding the chambering of any factory .243 Win?  Or, since it is for the time being, mine to be used for shooting cast bullets at moderate velocity and pressure, should I just leave it in .243 and perhaps add a plate to the loading gate stating that factory ammo is a no-no, consider Hodgdon start loads as max loads?  The Niemiller would require custom headspace gauges whereas I can rent the .243 gauges for $7.  Also, no payment to a machinist to modify the barrel and a sizing die.  Oh, decisions, decisions!  One thing I gotta say, the receiver is obviously a much higher quality of steel than a US Krag.  I could play with it as is for awhile, knowing it's in my possession, unless something sudden should happen to me, and I could always turn into a Niemiller later.  I know I wouldn't want to meet my grandson on the other side at an early for him date, because he got an unsafe rifle from me.  Well, I have time to think it over, I have a lot of other little projects going on, no money for a machinist at present, so I guess I'll just let the things gather dust for awhile longer.  I'll consider all advice that you guys might wish to give.
