RE: 125 gr nosler partition
I couldn't get the 125's to perform well either. I switched to the Hornady SST 129 grain. Nice 3/4 to 1"groups. Does a great job on whitetails too. Last season I dropped a doe like she was hit by a bolt of lightning and a buck only took 1 jump after the hit. He piled up on the landing. Both shots were at about 80 yards
