shooting on a shoestring

New Model S.S. Blackhawk 4&5/8 in .45Colt manufactured in fall of 2010, bought new by me from Collector's Firearms in Houston.
Barrel slugged 0.450" at muzzle and same all the way through, no constriction, tight, but very shinney for S.S.
Chamber mouths 0.4515 to 0.4520, works out well with 0.450 barrel.
These dimensions also work well with the nowadays 0.452 moulds.
Trigger was at 3.5 lbs with little creep out of the box, better than expected (although I removed all creep and lightened to 2.5 lbs before I shot it).
First thing I did was take it apart, do the trigger, check dimensions, look for burrs, none found. Clean pistol.
Barrel/Cylinder gap 0.006 and square.
First crack at the range today, load 18 grs 2400 pushing 454424 shot groups between 2 and 3" at 25yds rested. Good enough starting point.
Ruger has had some issues with .45 Colt Blackhawks, I can testify. This one I doesn't have any bad dimensions, or bad habits. Looks like a nice specimen.
