Hi Rustam

The Leupold is an early model 2x20mm (2x magnification). The latest models I see are called FX-II 2x20mm. There is also a 4x28mm extended eye relief scope available from Leupold which I would like if using my 404 on longer range shots.

I don't know what the 100 yard FOV is, I have never gotten around to checking this. The idea of the EER scope is to shoot with both eyes open which gives you a full field of view with the aiming point superimposed on it. Originally I put the forward mount on the 404 for a single point sight (green dot) and while it was great for game shooting it was difficult to use for precision target shooting (developing loads etc for the 404).

With the mounting in low Weaver rings the sight picture is attained just as quick as open sights and is more like shotgun shooting. You do have to have both eyes open just as you should for shotgunning and you know how quick that form of shooting can be.

While I shot my buffalo with open sights (I had not mounted the scope at that time) I did miss not having a scope sight as I had always been used to on my other rifles so I would not hesitate to use this setup on the 404 all the time now.

I think for trying to thread a bullet through brush on animals the scope has a big advantage over open sights and will easily hold its own on running or charging shots.
