This was made to replace/upgrade M118LR for a better/more stable powder. This uses the legendary 175gr Sierra Match King. No issues with the ammunition. Accuracy is something to debated. I was getting cold bore fliers (or at least it seems) from as little as taking a 200yd round trip to the target and back. Groups were still rather impressive, but our 175gr FGMM to date is my winner for best groups.
