Ned H. Roberts

Major Ned H. Roberts (1866 Goffstown, N.H. -- 1948), was an American hunter, competition target shooter, gun writer & editor, ballistician and firearms experimenter.

Mann and Adolph Otto Niedner had previously developed wildcat cartridges in .25-caliber made by necking down the .30-40 Krag and the .30-06 Springfield cases.

[3] Roberts was a perfectionist and there followed years of trial-and-error testing which involved the making up of literally dozens of barrels for his .25-caliber wildcat, with different chambers, groove dimensions and rifling twists.

The result was availability to an elite audience of especially keen and affluent shooters of the original wildcat .25 Roberts cartridge, designed to be capable of firing 1-inch ten shot groups at 100 yards from a rest with a telescopic sight.

The .25 Griffin & Howe differed from the .25 Roberts only with respect to the New York company, skipping one step and opting for a slightly longer cartridge by leaving the 7x57 Mauser case untrimmed.
