Forster full length sizing die & Forster micrometer seating die. I also have a Lee factory crimp die, but haven't used it or needed it yet.
I'm getting excellent accuracy with my hand loads with 20" barrel.
Love mine shot a couple coyote w it. The factory ammo is pretty good haven't loaded yet Hornady has a free bullet offer w there dies. The factory ammo is starating to become more common around then it has been
Love mine with an 18" Odins work barrel and adjustable gas block running an Omega can. Very accurate. Using Redding competition bushing dies.
Love mine. 18" I use the RCBS die set with a lee factory crimp. Getting my best groups with bowler 120's and H335
I'd if it has been said yet. When it comes to mags just buy the Alexander arms ones worth the little extra money and a adjustable gas block or a rifle length gas system
I been running a grendel for about 5 years now. It’s a great whitetail and coyote round. I’ve always used the 123gr class bullets with either h335 or 8208. I had Shot it as far as 700 yards when I was messing with it more a year or two ago. I started Shooting PRS and kinda laid it down but I’m wanting to do a little load work up for it and really start to stretch it’s legs. Build spec are seekins sp223 upper abs lower seekins v2 mod rail, JpEnterprises match 22” Barrel with their gas block and tube and muzzle break, fail zero bcg, and Geisel high speed national match trigger. Great hunting rig pretty good for accuracy and steel.
Looks like I'm late to the party. I'm using a 20" T-box barrel, JP bolt, SLR adjustable gas block,using SIG M400 receiver set. I use the 123gr SST factory loads for hunting and reload that brass with 123gr SMK using 8208 xbr for target shooting. I haven't used it for any matches yet but planning to run it next year. Planning to build another with a 16" barrel in the future
