I got the two restoration projects out to the range yesterday.
Both shot very well, with the Enfield breaking sporting clays at 50 yards and easily holding "minute of paper plate" wonderfully at 100 yards. It helps that it has a VERY light trigger that almost breaks if you blow on it hard. I think that if I put one of the micrometer sights on it instead of the battle sight, I could get some serious long-range accuracy out of it. We'll see if I can find one of those sights cheap.
As for the Springfield, it was shooting awesome groups at 100 yards, only it was hitting 6-8 inches left, placing them just off the plates I was shooting at. A close examination of the rifle showed me that the rear sight base had drifted left somehow, probably back when it was still a drill rifle. This was easily fixed once I got it home since there was an alignment mark on both the sight base and the receiver and I just had to use a hammer and brass punch to move it back. It didn't really want to move, so it took some hammering, but that's good as hopefully it will not want to move back out of position again.
It was a good range session, if short, except for the fact that it was ridiculous hot out there.
