Just as a follow up.
I went back through my logbook and the rifle had a new barrel installed and action bedded in November 2009. The barrel has 926 rounds through it to date.
Best group was .4325 for 5 shots on 7/23/2010.
The last good group was shot on 4/20/2012 and the gun was not shot again until 3/15/2013.
The rifle was not shot for almost a year. It was cleaned before it was put away in the safe.
I am using Hoppes on the bore today and the patches are coming out clean.
I use the Otis system and pull the bore brush from the chamber to the muzzle.
The crown looks good and the rifling at the crown looks good.
The preferred load for this rifle is 52 gr SMK and 38-38.4 gr. H380 loaded at 2.432 which is -.080 in. off the lands.
I have actually shot 5 factory rounds through this gun and my loads are better and none of them are barn burners. I do not chrono the loads. My loads are all well under maximum published loads for the caliber and show no signs of over pressure.
