It has been my experience that higher BC long range bullets are harder to get to shoot accurately. My Barnes 6.5 120gr TSX/TTSx, excellent accuracy. Try the 6.5 127 LRX & accuracy is dismal. Same results with Nosler . Great accuracy with their 6.5 140 gr AB bullet, but terrible results with their 142gr LRAB. Have had similar results with other so called long range bullets. It appears there is less surface contact between the bullet & the rifling.. Which results in less stability.
