Raimey,

The 25-35 and 30-30 are based on the 38-55 case. They are the 1st 2 American rounds developed for smokeless powder. As Piper stated above. They were introduced in 1895 and intended for use in the Winchester '94. Hogdon shows loads using the traditional 117 grn bullet ranging from 25,000 CUP to 36,600 CUP. http://data.hodgdon.com/cartridge_load.asp

In short order there were also the .25-36 Marlin and .25 Remington, which was rimless. Interesting side note, in Wikipedia they state the 6.5x52R and the 25-30 are the same. Which as 400 Nitro Express has shown they are not, based on proof pressures.

RWS produces the 6.5x52r, I would like to hear their take it. As I believe Jani is correct. For years they were considered the same by sportsman...

Even AccurateReloading states them as the same in their online guide.
