I must admit to a long affair with the .303 and the SMLE. I presently, and for many years, own an Enfield and Lithgow No.1 MkIII* and MkIII, and a Savage and Long branch No.4s. I was with a friend shooting Garands and Enfields a couple months ago. We were pinging a rock in the bottom of a quary at an estimated 500 meters. The Savage No.4 with military ball (pakistani?) was a consistant hitter. Most wouldn't believe this, but I cranked up the rear sight to the proper mark and easily stayed on the 2'x2' rock. The garands would too though.
I have previously written about my MH rebored to .303/.375. It will prove a great round. I have had too many other "priorities" and not enough reloading time to do much with it.
Good stuff.
