Wise man says not to fix sumthin' that ain't broke or not out of sync! However, if you suspect the rifle should shoot slightly better, then two patches of JB Bore Paste - each patch going 10 swipes up & down the bore with a black nylon bore brush... then 10 with a smooth-sided patch jag.... then a full solvent/alky flush-out & oiling. No short strokes with brush or jag... straight down - then straight back up. It'll make your patches black as coal so don't get nervous. Just stop right there. Inspect the bore afterwards with a light. Go shoot it this spring & see if it improves. Let us know what happens.
I did a similar process although I used a brass brush and changed patches every 20 up and down strokes with new JB each time. I did a total of 200 up and 200 down on my stainless Omega which would not load any sabots I could find. I can now load Hornady bullets in Harvester sabots (with a small amount of difficulty). My rifle shot great from the start and I hesitated doing this until I got so fed up with loading difficulties that I decided to either fix the problem or get another gun. I am now very satisfied with my rifle and just got the first elk with this rifle. I think the stainless barrels from T/C are probably the ones that need the polishing the most due to stainless machining characteristics which tends to leave surface roughness. I have not noticed any change in accuracy although it shot cloverleaf patterns at 50 yards from the start and still does. I like stainless; however I think there is probably more need to "shoot in" the stainless barrels or polish them.
