I just started working on a 120 GoldDot load for my grendel 18" using H335. I used the 335 for the same reasons 'FLShooter' stated. I went from 27 to 28.3. Around 27.5 looked good, but didn't get where I wanted until I used my C-products magazine and loaded out to 2.7". Shot a 5rd group .7, and today a 3 shot .432 group. Today was primarily to chrono. The average for the 3 rds was 2464fps, SD 5 ES 10,,,I'm happy, and ready to try it on some hogs. My main powder for 120-123gr is AR-COMP, but I wanted another since arcomp has gotten scarce around here. LR55 is probably right, 27.5 to 28.5. Mine started to scatter at 28.3. Good luck
