Go to a gunshop that stocks Bushnell scopes. They should be able to help you.

Take it to a well stocked hardware store and see if they have a screw that will work.

This happens will all firearms. what happens when the bullet leaves the bullet is a decieving "rise" of the bullet. The reason for this is the Line of Sight (Scope View), angles down and away from the Line of Departure (Barrel). The bullet actually never rises and is in fact continally falling away from your rifles Line of Departure but because this is higher than the Line of Sight the bullet seems to Rise than fall to the set distance in the scope (i mention set distance and not zero because you can change your Minutes of Angle on your scope to increase and decrease range)

this is a chart that illustrates what i just said.

now that you understand that you should take a good read into Exterior Ballistics. this is the Mathematics of your fireamrs trajectory ( I say your firearms because your bullet's flight depends on the length of the barel which will vary from gun to gun) this science of shooting will teach you how to understand bullet Grain and Volume relations. understanding the Feet per second of your rounds and how the affects you. teach you about shooting in high pressure and low pressure environments and extremly windy environment.

now there is alot of math to all of this and its hard to find it all on the net and if your not that great at math you can do what i do bc im lazy and im not a sniper im just a hobby kinda guy. '

Sierra Infinity V 6 Ballistics Software. I dl'd mine off the net you might have to buy it depending on how resourceful you are. it is well worth the buy. You can punch in the daily variables (Barometric Pressure, Temp, Humidity, and Altitude) (of couse with your bullet as well) and it will give you a "Cheat Sheet" for those conditions stating Windage and Elevation adjustments per decided incriment (50 yrds is standard) then you take that to the range and (bring a laptop if you got it and arent embarrased (som1 might even help you tune in the variables) hope this helps if not ill check back in a bit to see how you did

Google SWFA ......they sell about 20 different brands of riflescopes, with pix, desriptions and prices. It's a good source for info, even if you decide to buy one of the same scopes at Walmart. Check out the Bushnell Trophy, Nikon Prostaff, and Tasco scopes, in particular.

Also, there is a website I belong to, originally started just for the Ruger 10/22 owners/fans. You can visit it and join for free at - www.RimfireCentral.com
