I have a VX-3 3.5-10 x 50mm matte. The last couple years I have elected not to use the gun after its sporadic shooting. Last year on the range the bullets were spayed all over the target. The browning abolt checked out fine so I narrowed it down to the rings or the scope. I just purchased brand new rings and while removing the old i realized the bases were possibly loose.
After thinking I fixed the problem, I mounted the Leupold and headed to the range. 1st two shots were from 25 yrds and grouped nicely 2 inches right and a inch low. I then backed to 50 yrds 2 more shots grouped nicley, but 2 inches right and 4 inches higher than the 25 yrd group. I backed up to 100 yrds and shot 4... nothing hit the paper. Went back to 25 and 50 and hit same spots i hit at the distances before I went to 100yrds. The 3 inch high difference at a 25 yrd increment has me very worried, then not even touching paper at 100 has me perplexed.... Is this a scope issue? It should shoot the same from 3.5-10 power correct?

ill try to post a picture of target if I can figure it out
