Mauser8X57. Put the sorting aside for a minute.
What is your trigger pull set at? 2-3 pounds is best. Heavy trigger pull ruins good groups.
Range time improves groups too because you learn when the trigger is going to trip. So, no sweat on more trips to the range.
Hornady SST's are a better choice for cheap bullets.
Nosler Partitions are usually spot on weight wise. Cost is up there though.
Check out the BC and you'll make better choices in the future.
