I wouldn't give up on the Grendel.
I shot mine again today and no pressure signs with my handloads.
I shot 123 SST's seated to factory spec of 2.245 and they went 2465 fps over 31.1 grains CFE.
They went 10 fps slower than some I loaded to 2.233 with 30.8 grains CFE.
85 grain sierras loaded 1/2 grain under max load of H-322 went 2775 fps.
Both shot around 3/4 inch at 50 yards with a fuzzy holosight in bright sun and lots of wind.
I've shot some half inch groups with it and one went 1/3 inch.
The tight throat thing went away on my barrel.
