Took both my M-38 and M1 out to the range yesterday. My M1 put 13 of 16 rounds in six inch area around the bull with one in the bullseye. The M-38 on the other hand shot a foot high and a tad to the right. Rear sight is all the way down. Is there solution? I know these guns are sighted in for twice the range I was shooting at yesterday which was at 100 yards. Thanks for any replys.
