I still a 1974 birth year Ruger # 1 in 22/250, the rifle shoot 1/2 inch groups right out of the box. I used Bruce Hodgdon load of 38.0 of H-380. Supposedly Bruce named "H-380" for his load of 38 grains that he used in his 22/250 rifles......this was story often printed in the gun magazines in the 70's. Not sure if true but the load certainly worked in my rifle.
