I only wanted to cover the development of the #48 in my 2007 Gun Digest article; its usage was another matter. The popular Long Slide was intended for the long range military Springfield matches. Thousand yard competitions were common, and some civilian clubs held 1,200 yard contests. When Townsend Whelen published his glowing evaluation of the new Lyman in February of 1912 (OUTERS BOOK) he included elevation and windage dope ( 30-1906 150gr, 2,700fps) out to 1,000 yards. Hope this adds some clarification.
