have 2 257 roberts in my safe a M70 made in 51 and
a 760 remington pump forgot when it was made. But anyway
both will shoot under a inch with the right load. My
M70 really like those 117 semi-round noise Noslers until
they ran out. I shoot IMR 4064 with all the lighter bullets
and W760 with 100gr bullets. Anything heavier I use IMR 4350,
IMR4831, H4831SC,and RL22.
