Once upon a time, when I was but a wee lad in PA, I hunted with a Remington 760 in 270 Winchester. My father, knowing how well young boys can take care of rifle scopes, topped my rifle with a good old Tasco World Class 3-9x40. It took a few years, but eventually we noticed that the scope had a significant POI shift from 3X to 9X. I'm talking a good 6 MOA shift here, not a half an inch at 100 yards. He sent the scope back to Tasco and they repaired it. It worked fine for years after than and was still good to go when I sold that rifle to pay the rent one winter in AK. Today I was out tuning up my Savage Mk II-BV (pre-accutrigger). It's got a no-name 1.5-4.5X scope on it that came with another rifle years ago. We've been having some raccoon problems (lost two chickens so far) and my FIL got me one of these for Christmas:  So today it was sunny and I had the time. I went out and shot a few 10-shot groups:  The three groups of interest are lower right, upper right and upper left. They were fired in that order. The lower right group is 4.5X at 25 yards. The upper right group is 1.5X at 25 yards. The upper left is 3X at 25 yards. It looks to me like somewhere between 3X and 1.5X the POI shifts down and to the left about 1/2". 1/2" @ 25 yards is about 2 MOA. I doubt I'm going to trash the scope over it - I rarely shoot further than 50 yards with this rifle and I plan to simply leave the scope at 3X for raccoon duty. But it got me thinking... This is why I no longer buy cheap scopes. |
