That's a nice group!
I'll do some research, but likely will go with the 6.5 - more data, more parts and brass and such.
I do reload. Dillon 1050 for mass quantities and a 650 for less. Rockchucker waiting to be (re)used for precision.
Have shot IPSC and 3 gun in New Mexico, but not here yet.
Just moved to Moyock, NC and have not gotten with a club. Ranges are different here.
Long range rife is a JP heavy barrel Grendel. Shoots well, but not like that group you sent. Course, could be the shooter...
I'll probably have to sell an Open gun to be able to afford to play this game, but I do have a back-up.
