Handgun scopes are usually referred to as EER (Extended Eye Relief) and have longer eye relief than scout scopes, which are usually called IER (Intermediate Eye Relief). Some handgun scopes will work on some scout rifles for some people; many have so much eye relief that they simply can't be mounted on many scout rifles. The further forward the pic rail extends on your rifle, the more likely you are to find a scope that can be used.
I have long neck and arms, which makes it even more important to be able to push the scope further forward and also makes the use of handgun scopes pretty much unworkable. There's really no way to know for sure which combinations will work for you until you have experimented a bit with a few different ones. Even when you do that, and think you have a handle on the numbers you need in terms of inches of eye relief and length of pic rail forward extension...you then try to compare those real world numbers to published manufacturer's specs...only to find that those numbers are way, way off from reality. There's no substitute for "try before you buy".
The next best thing is to have a crapload of assorted rifles to try new scopes on until you find The Perfect Combo. This solution is expensive...but fun...
