I recently acquired a rifle which the previous owner called a .308? , but after further inspection, I realized that it had some interesting markings. It is British and says .303 but, it has been upgraded to a composite stock, and Im not sure if it is an Enfield, or something else?. The Markings are: A Crown, G R, B. S. A Co., 1917 ,Sht. LE III *. I know very little about it, other than what I have Googled . Also the barrel has England 1883 ,.303, 2 22", another 1883, 18 a fraction #, looks like one half; tons; also some on the other side; some other stuff which I cant make out. The ammo is ,well there are two different kinds. R (an arrow) L 31.and VII. The other is REM-UMC 303 BRIT. Could some one please give me some info
