Some of these commercial Ross rifles were made after the Government took over the Ross factory, using up the parts on hand when possible.
The "303 Ross" stamped on the barrel is right for a sporter, but the "LC" barrels were for Military use.
The commercial Ross sporters had a serial number on the left side of the barrel near the receiver, in numberals about 1/8 inch high. If you remove the butt plate, there MAY (or MAY NOT) be a serial number stamped on the inside top of the butt plate.
Have you fired it? If so, does it blow out the cases? Does it split any fired cases, and if it does, you are going to have to anneal them. If you don't know how to anneal cases, PM me.
If you reload, keep all fired cases for this rifle seperate, and NECK SIZE the cases only. You can buy a LEE set of reloading dies that will neck size the brass, or alternatively, put about a 1/8 inch BRASS washer under the regular resizing die when you are reloading. Full length resizing will weaken the cases after a few loadings, and you WILL have case seperations.
Make sure that the bolt is assembled correctly and locks fully. Use a small flashlight and shine it into the rear of the receiver while closing the bolt to see the locking lugs turn. It they fully engage the receiver, you are good, but if they only engage about 1/7 th. of the receiver and a lot of the lugs are showing, you have a big problem. This is a set of pictures that I made up to show people.

WARNING........ I can make it to the front gate in 3.2 seconds...Can you do it in 3.1?
Buffdog, thanks much. I have studied your bolt assembly information before and have read the posts on neck sizing for large chambers. This forum is great. It renewed my interest in the Ross rifle. I have owned this one for over 35 years. I cannot remember if I fired it or not. The mystery deepens somewhat. Hopefully I will download a picture of the left side of the barrel with serial number and ," MADE in CANADA" stamping. The barrel is a good deal slimmer than that of the military 1910, with a smaller front sight mount, without screw holes for a sight guard. The barrel is 26 in. bolt face to muzzle as opposed to 30 1/2 . The barrel diameter just forward of the sight mount is .580 compared to .653 for the military M1910. " 04" is stamped upside-down inside the toe of the butt plate( last two of serial number). I surmise this is a 1910 R with an , "LC" stamp ?????
