so I was looking at mueller scopes and I found that the 4.5-14x40 mildot costs pretty much the same as the 8.5-25x44. why? is the higher mag of poor quality? I was planning on buying one of these for my savage stevens in 308. I have heard great things about mueller scopes having alot of bang for the buck. this gun will be for bench shooting only. looking to do 100 to 600+ yrds.
