This is from a short article in the 12/30/1899 issue of "Army and Navy Journal". Note that my great grandfather would have been in the 14th U.S. Infantry Regiment mentioned in the article.

Owing to the reports received by Chief of Ordnance since the outbreak of hostilities between the United States and Spain, and as a result of campaigns in Philippine Islands, the Department of Ordnance of the  War Department has abandoned the idea of a clip for more rapid charging of the magazine of the Krag Jorgensen rifle. Operations in the field have conclusively shown that the Krag Jorgensen rifle is seldom used as a magazine rifle and when so used the five shots in reserve are entirely adequate. The United States rifle can be fired as a single loader from twenty-five to thirty times a minute, which is rapid enough for most occasions. In the Philippine campaigns the magazine has seldom been used and it seems that this is exactly the kind of war which would call forth such use, if any would. On one occasion, at the outbreak of the insurrection in Manila, the 14th Infantry came to close quarters with the rebels and used the magazine with good effect. No difficulty was found by the troops in regard to loading the rifle rapidly enough.
