Not quite. The chamber adjustment was actually just me trying to make "the best of a bad situation" with my limited tooling. A good chamber will have at least some throat. Mine has none. With the "as found" chamber, any amount of bullet over say 0.2245" would have just shaved off. My bullet fit is still on the fat side (probably bigger than I need) but now there should be no shaving.
Even though my chamber may not be "ideal" by normal standards, I like the way the marks look on a chambered round when I pull it back out. The boolit is not touching any rifling, but a little bit of the the taper on the boolit is mating with the lapped in taper at the end of the chamber.
I am getting some amount of sizing (mostly about a 0.0005" reduction across where the boolit is biggest) of my medium soft boolits during seating in the case. After I give "as cast" an honest chance, I will probably try to fab up something to do some test runs for bullets sized down some. This will be a low (time only) investment to see if some other diameter works better.
I did get 15 rounds loaded. Boolit seating was light, smooth and generally felt great. I used 3.2 grns of Promo (Red Dot equivalent). This is about as low as I can go before I start worrying about poor metering from my measure. It has worked pretty good for me in other "pop gun" loads. Before next weekend, I need to figure out what to put in the other half of my brass. My Titegroup would be the obvious choice, I just do not "feel" that it will do any better at this point.
