I have a Remingtom Eddystone 1917 rifle unaltewred. It is a very accurate target rifle as issued. I have been using my own cast 173 g. bullets with gas checks and 20 g. of 2400 powder. It really likes s that loasd as it sure is accuratge. The U.S. Army was still usimng them early in WW in some of he early battles in the Pacific before changing over to M-! rifles.
