Today I really got a chance to take my Eddystone M1917 with a Johnson Automatics two groove barrel and run several loads through the rifle. The rifle is equipped with a Parker-Hale PH5B rear sight with variable PH eyepiece. First I shot a group at 100 yards with .30-06 Springfield ammunition loaded with a 168 grain Sierra Matchking BTHP bullets. This load I use in My M1icon National Match with great results. X's and 10's all day. When I shot these rounds in the M1917 Enfield the bullets are keyholing with a nice grouping at 100 yards!! When I used the standard M2 Ball round all of the shots were in the X's and 10 ring. Anybody knows what is going on here? I have shot the 168gr Sierra Matchkings in a two groove barrel on my Remington M1903A3 with excellent results.
