Im new to the forum and just getting into long range hunting. My rifle is a FN SPR 300wsm, topped with a leupold Mk4 4.5-14 tmr set in burris extreme rings, brake is a JP.
The best group Ive ever shot. Details: 190 berger VLD, norma brass, H4831sc, WLR primers. Groups were 5 shots at 100. Im working on a drop chart now and this load seems to be holding 1/2 moa so far in field conditions out to 300, which is the longest Ive had the oppertunity to try to date.
