Whole lot of SXS DRs chambered in 303, as one of the earliest high velocity cartridges for thin skinned African hunting. I have a Purdey from 1900, and early Nitro-proofed gun. The Lee Speed in 303 was a very, very popular hunting rifle from about the same period through the 20s. (And avidly collected today. If you have one, let me know, I am always interested.)

And, God only knows how many ex-military rifles, in moderately or totally-rebuilt form were made up from the 200 zillion Long Lees, SMLEs, etc et that were sold surplus, left in countries all over the globe after the fighting stopped, or simply taken home by their former owners now out of uniform. 303 as a hunting cartridge? Well I should say!!!!
