Happy leap day everyone. It may be that I am getting older and lazier but I haven’t been to the range since November. My renewal date is around the first of the year and I haven’t hardly even thought about going. It kind of makes me wonder if I should keep up my membership if I am not going to use it.
Another possible reason is that since I have setup my basement, pellet trap I use it multiple times a week. So, I feel less of the need to go to the range because I am always shooting without going anywhere. Recently I upgraded the scope on an air rifle so I am going to talk about the process today.
My son has a Crossman 760. It is a straight tube (non-rifled), multi-pump, bb/pellet combo. It is one of those classic bb guns. I can remember my cousin’s had the same one in the 1980s. My son’s looks exactly the same but today’s model has a sleeker, more updated design. It has a 3/8 rail for a scope addition.
When I purchased my first air-rifle, it also came with a very in-expensive 4×15 scope. It truly is better than nothing but for not much money you can do much better. But, the better part of my motivation was to put a scope on my son’s rifle. I figured I would upgrade the scope on my rifle and move the old scope to the 760.
Since the 760 is not rifled, it is not likely to be the most accurate of the bunch. By my reasoning, a significant scope upgrade would only marginally be of value on that rifle. The sights aren’t that great either and my groups are more like 2 inch groups with the 760. Additionally, I am noticing my eyesight is starting to degrade rapidly. Even this scope would help.
I took the old scope off and sighted the new scope on my rifle. It is shooting pretty good and I think the $40 investment was worth the cost and effort. I put the old scope on the 760 and the picture above represents how things went. Despite the fact that things were pretty dialed in my first shot was six inches to the left. As I kept working at it, I kept walking right and up. The final three shots above the center is where I left it.
Keep in mind that changing the number of pumps or the projectile will also change how things work. In my case eight (out of ten) pumps with a BB (5gr, one of the lightest projectiles) at ten yards will likely yield lower impact for heavier projectiles or less pumps. Given the same conditions, farther distance will likely have some drop as well. I think it is about perfect.
One other thing about inexpensive scopes is the adjustments are kind of poor. It is marked as on click per 1/4″ at 100 yards. So, at ten yards 1/4″ is supposed to be 10 clicks. But when it makes no clicks, you are not totally sure what the adjustment actually is. They also tend to act erratically sometimes by having different results the next day because something finally sprang into place. Some people actually tap on their scopes after adjustment to try and help them set in place.
End Your Programming Routine: I am happy to report that things were still in place the next day and I think this is an improvement over open sights. I do have a picture here somewhere with some previous testing I did but I couldn’t find it. And there is a real improvement in my rifle with the new scope on it. Win-win, I say.
