I have a 6.5-284 Norma with a .188 freebor .297 nk.. The barrel is a Schnieder #5 Polygon 1-8 twist 29 inches long. I am having troubles finding a load for hunting at 300 yards +. My groups at 100 yards are at the 1 inch and at 200 2 inch with Bergers 140 VLD Hunting bullets running 3050 with 50 grains H4350 and CCI BR LR. Do iI need to SLOW it down, or should I try the Sierra Matchkings to hunt Deer and Elk from 200 yards on out to about 800 yards. WHAT SHOULD I DO GUYS????
