re: 6.5 Grendel guys and shooting questions....

As others have pointed out, shooting with or w/out a suppressor will change POI due to barrel harmonics. Based on it’s pedigree, the Grendel should be one of the most accurate cartridges created shooting sub 300 yds. The parent case is a .220 Russian or 6PPC which is the most accurate short range cartridge ever created (100-200 yds). The 6.5mm bullet is known for its high BC and lethal accuracy. Combine the two and it’s a great cartridge. I would expect 3-shot, 1/2” groups at 100 yds with a decent shooter from a stable bench.

If you sighted in the rifle with a suppressor, you should be hunting with the suppressor.
