I shot my model seven bolt gun at the range yesterday with 200 grain corelocks loaded fairly warm with IMR 3031 powder and they did just as I expected 3/4 inch 4 shop group exactly 2 1/2 inches high at 100 yards. I put 3 Hornady 200 grain LE's in the rifle and they shot exactly dead center 2 1/2 inches below the corelocks. The recoil felt the same. I have chronoed the LE's and they are 2100 fps. Could it be the corelocks are much hotter to have shot that much higher? There is absolutely no pressure signs on the corelocks. The primers are not flat, the brass is not stretched and extraction is good but the handloads don't flip out like the LE's when the bolt is opened slow. Any answer will be appreciated.
