Basically, shooting a 1" group at 100yrds with your 1.75-4x scope has the same margin for error as shooting a 1" group with a 8-32x56mm Nightforce scope AT 1,000yrds!!!!
1" groups primarily don't happen at 1000 yds because of many more factors that come into play that FAPP aren't factors at 100 yds. If the gun is capable of it, 1" groups with a 4x scope at 100 yds are very possible. Trying to equate 1" groups at 100 yds with a 4x and 1" groups at 1000 yds with a 30x scope is illogical.
The problems that the OP is experiencing are most likely the shooter, the gun, the scope not holding zero or the scope mounts. If I read correctly, he has been shooting 3" groups at 50 yds, which he should be able to do at 100 yds with open sights.
