Very boring cartridge. The worst I ever got was maybe 1-1/2" groups. I've shot Hornady Interlocks, Nosler Partitions, Hornady GMX, Barnes 129 gr. TTX Speers and a few more. I had real good accuracy results with old 140 gr. Sierra Game Kings. My deer load is a 143 gr. Hornady ELD-X, Lapua case and 46 gr. of H4350. That is an easy 1" load too.
