The lands MIGHT be getting a tad burnt at the Leade (portion of the bore just forward of the Chamber), but I would have to see it in order to judge properly.
The view from the Muzzle shows that there is certainly lots of meat there and the Lands are square-edged and sharp, the way they are supposed to be.
If you really want to see how well this rifle can shoot, load up 20 rounds of .303 with 38 grains of IMR-4895 powder and a Sierra 180-grain Pro-Hunter bullet. This bullet has a FLAT base; Enfield rifling (which this rifle most definitely uses) has a decided preference for flat-based Bullets. Now her is the tricky part: you seat your Bullets to the overall Length of a Ball Cartridge; with the Sierra bullet, this crowds the Leade just a bit, which is safe in a new rifle but which this rifle just MIGHT like.
Note carefully: this is NOT an intense load but it does reproduce the by-test most-accurate VELOCITY for the .303 round in this rifle: 2250 ft/sec or very close.
You BENCH the rifle and rest the Fore-end of the Stock, JUST forward of the Magazine, on a padded rest (small sandbag works fine). Your Target is at 100 yards and it is the bottom-left-corner of a 12-inch Black square which is on a 2-foot White background. Trigger Control is essential, as is Breathing Control. Ideally, you will sight the Rifle on your Target, take a deep breath, take up the SLACK in the Trigger, allow part of the breath to exhale slowly until your are comfortable, STOP exhaling, then check your aim for a final time (the UPPER-RIGHT-hand CORNER of your Front Sight should JUST TOUCH the Bottom-Left Corner of the Black)...... and SQUEEZE the Trigger.
Open the Bolt and let the Rifle COOL for a minute.
You take your SECOND shot ONE MINUTE later, NOT immediately. This gives your "Sniper's Zero" for the rifle. (BTW, it is also called a "Hunter's Zero: first shot out of a dead-cold barrel with a follow-up in 1 minute). Frankly, if you can hold it, I would not doubt that THIS rifle can put them both under a Quarter.
This is not an "old Army gun" by any means. This one is a Precision Instrument and must be treated as such.
BTW, the marking on the Butt Socket is absolutely correct for a COMMERCIAL Target Rifle. It has NOT been scrubbed.
Hope this helps.
