Be aware that Lyman rifling and muzzle crowns tend to be a little sharp when new, and prone to cutting patches. That can knock accuracy at first. You can "shoot through" it and let normal shooting wear things a little smoother, with accuracy taking a sudden jump at around 200 shots.
Other approach is to help it along for better accuracy quicker. I've done both with complete happiness, but I'm more prone to shooting through. I always need the extra shooting practice.
For the rifling, lotta guys get one of those green Scotch scrupping pads, cut off a little piece, drape it over their jag and pump it up and down the more a dozen or 2 dozen times. It certainly works, and I don't know of any demerits.
Fix for the sharp crown might sound a little radical on first hearing, but it's in the same league of results without harm. Get yourself a piece of 400 wet/dry, tear of a square a little bigger than the muzzle. Lay the patch over the muzzle and press down firmly with the ball (or pad, if you prefer that word) of your thumb. Rotate it around completely maybe half a dozen turns.
Lyman bores seem to remain a little tight for a few hundred rounds. You're likely to start out with .015 patches and .530 balls for the first 400-500 shots, then notice starting/seating effort getting pretty easy and maybe accuracy falling a little. Bump it up to .018 patches and watch the accuracy jump.
At around the 2k mark I started feeling the same looseness, so went to a .535 ball. Dang near couldn't get the ball started- took a good hard whack on the short starter. Range guys like that, but I don't for hunting. Faced with either going to a .015 patch with the .535 ball or dropping back to the .530, I subbed a .020 patch with the .530 and found happiness. At something north of 4k shots in my most-used rifle, I'm still happy. You're call, but just be aware that you might need to tighten things slightly at the 500 mark or so. If you try to start out with .530 balls and .018 patches, figure on some pretty hard starts/seating.
