SCOPES, EXTERNALLY ADJUSTABLE
Warren page wrote that the externally adjustable scopes hinder accuracy.
I have been shooting my BSA Martini, 50 yards, 5-shot groups, GECO Semi-Automatic ammunition, with three different scopes. Here are the records:
30X Lyman STS, 30 groups, .534” average group size
Tasco # 705 Externally Adjustable, 6-18, 4 targets, 40 groups, .481” average group size
Weaver T36, 80 groups, .429” average group size
While that Lyman/Unertl/Fecker/Litschert/Davis scope may look good on a rifle, maybe it is causing some inaccuracy.
