Thread: Best way to go about shooting multiple groups

Cheers Zimmer, i like your first point about skipping groups. I loaded from the min to max off of a Nosler Reloading chart going up in .5gr increments so I roughly know what i should be expecting speed wise. Only thing i have changed is the C.O.A.L. mine are at 3.350” and the load data for the weights and speeds were at 3.290” for the 160 accubonds out of a 7rm. Should i be expecting faster or slower speeds with this increase in C.O.A.L.?

I’m shooting a Hell’s Canyon Speed so the barrel will probably heat up quite quickly.
