In order to utilize the Springfield cartridge, the gun needed definite modifications. These included a new magazine, a new magazine well, a relocated foregrip, and new reamed chambers. Unfortunately, the chambers weren’t reamed deep enough, which caused the cartridges to be jammed into the chamber. That extra force proved too much for the extractor, and many spent cases were stuck in the guns. The rifle’s complicated and delicate nature often prevented field repairs and undoubtedly cost men their lives in the trenches of World War I.
