As one of the few rimfire cartridges to see military service, the 313 gr (20.3 g) bullet and 1,400 ft/s (430 m/s) was respectable compared to its contemporaries.

The most popular arms chambered for this round were the Vetterli series of rifles.

With a 334 gr (21.6 g) bullet, it is adequate for deer, and only at short range.

[1] The original round's case was made from copper which held a round nosed lead bullet.

The round continued to be commercially available in the U.S. until sometime after 1946 with 310 gr (20 g) bullets loaded by Winchester (K4154R) and 300 gr (19 g) lead bullets loaded by Remington (R326).
