I'm loading 6.5.54 MS for my Greek 03/27 Breda. I use 34 Grains of IMR 4350 w/160 Grain Hornady Interlock #2640. I trim the case length to 2,110 and the col is 2.970. After I full sized the case I have been neck sizing them. Norma has cases for the 6.5x54. I am using a relatively low powder to keep it safe as the gun is old. I get 1" groups at 50 yards and 2" groups at 100 yards. This gun was the same type of rifle my Dad used in WWII when the Greek Army chased Mussolini back into Albania.
