Just finished load development for a new barrel on my 17 Rem. Lilja 1-10. It really liked H380 over anything else I tried - Varget, CFE 223, H335, BLC2. Shooting 20gr vmax. Shot practically identical groups from 25.5 to 26.5 grains. Using R-P cases. I test at 300 yards and groups are 3/4 to 1 inch vertical. I'm amazed at the accuracy of these little 20 grain bullets.
