How do you make sure it's level?
Also, I'll be shooting out to 500 yards in my match this weekend. It's the first time I'll be engaging past 200. Any tips for difficulties I may encounter? |
seriously though, every person is different so you'll pretty much just have to get behind it and compare it to something level.

If the scope has a flat bottom, the feeler gauge method works well. You can google it, it was on the hide, but I lost all my bookmarks, so no link. If you have some small levels that you can put on the rail, then a plumb bob hung in the room, or even a 90 degree corner will work as long as your walls are straight. |

OP didn't state what rifle, optic or mount but a better method I have used is an allen wrench slightly smaller than the gap between scope flat and mount/rail. Snug mount screws, insert allen key between and turn it. Shifts the scope level to mount, maintain pressure and tighten screws. Make sure to torque them to spec so look at the scope manual first. Very important if it is a variable power scope. When I did my bolt gun I leveled the entire rifle on my bench to the 1 piece mount. Then used the allen key to mount scope, then checked level with small level on turret cap and with plumb bob. It helps if the reticle isn't canted to begin with

Once you think you have your scope level you need to verify it.
Here is how you do that. Take a piece of cardboard about 36 inches tall and put a target at the bottom. Place the cardboard at 100 yards and fire a three round group at the target. Raise your POI 24 inches either with your elevation adjustment on the scope or your BDC and fire another 3 round group using the same point of aim. Take a string line to the target and verify that the second group is plumb with the first group and that the second group is in fact 24 inches higher. Doesn't have to be 24 inches could be 26 or 36 or what ever is convenient for you. The point being is that you want to insure you are tracking plumb and that your scope is moving in the advertised amount per click. In your case, figure out your drop for 500 yards and use that for a quick check after you do the above. |
