'Alan De Enfield' - posted this interesting page, from 1904, in a thread on the Milsurps Forum.
The Royal Artillery in 1904, apparently did some comparative firing of the new Short-Magazine Lee Enfield and then current .303 cartridge, against other service rifles.

The U.S. Krag was in the mix. (I'm guessing the 'Brits' didn't have a lot of .30-40 ammo). No details of the .30 caliber round that was used in the Krag.
It looks like it placed a close 2nd in group size, at 500 yards, of the rifles used.

Does anyone have an explanation for the "Figure of Merit" calculation? Is it the same as Mean Radial Dispersion as calculated by the US Army? More precise than group size, but very labor intensive. But an army ordnance unit has lots of free labor, and measuring the distance between bullet holes is a better use of a good soldier's mind than painting the rocks bordering the driveway.
