I bought a Tikka T3X Tact A1 6.5 Creedmoor but the weather has been so bad, I haven't shot it yet. I loaded up some 140 ELDM and 143 ELDX. This will primarily be a target rifle rather than hunting rig. Is there a clear choice between the two bullets I loaded up or is there something even better? My mission is to hit 1,000 yards this summer.
