RE: Line of Sight - Line of Bore Qn.
I am not exactly sure what you guys mean by angle?? there is no inherent angle built into a scope to allow the line of sight to cross the trajectory twice.
A scope can easily be adjusted to only touch the line of trajectory once, or cross it twice.
First off the bullet never rises. The angle comes from two variables.
Lowering the scope to cross the trajectory-the same way you can raise it to be above the trajectory.
Mainly the angle comes from the fact that trajectory has an ever increasing trajectory curve. Or in other words the farther the bullet gets from the bore-the greater the "bullet drop". This additional drop is what causes the bullet to cross the "line of sight" at either a close distance with a slow cartridge or farther out with a faster cartridge.
IMO what got you thinking about this was the post you had on the Encore base being tilted downward because of the barrel taper(with the longer base). IMO that post was erroneousbecause the base is NOT pointed downward becuase of barrel taper. I think that guy just made that up. Tom.
