Been shooting a Grendel necked down to 6mm and it shoots well with 107 grain sierra match kings,95 grain ballistic tips,and 70 grain tnt's.
Nothing has gone over and inch.
The 107 SMK's shoot the best.
Usually around half to 3/4 inch using 27.5 grains H-4895 and 31 grains CFE.
XBR8208 shoots well also but can spike easy on pressure so been using CFE and H-4895 the most now.
The 107SMK's have a B.C. of .530 and will try them at 300 and 500 yards later.
This variant is a lot of fun to work with.
