Evening Win-Mag - say that does look appropriate and aestheticly pleasing.
One thing I had to consider when I was searching out a rimfire scope was the parallax issue. RImfires are parallax free at 50 yards, centerfire scopes at 100 yds (rule of thumb as there are exceptions) So the old Bushnell banner 3-9X I’ve had since the mid 60s wasn’t the best choice for my rimfire. Luckily I had another .22 scope (4X) from the same era that worked until I got a more suitable one (2-7X)years later. I tend not rush things. :-)
The new rail is thicker than the old, raising the scope even higher. The present mount is a GG&G QD mount for an AR15 flattop, and it now brings the scope up to the perfect height for a nice comfortable cheek weld for me. That B&C stock changed the entire aspect of the rifle from a bull-barrel plinker to something more businesslike.
I also modified a Butler Creek loader to work with Ruger factory mags. After I get the permanent scope and mount, I'll go back to the range for more ammo testing. Meanwhile, gunsmithing on my surprise CZ 455 is next on the list.
I pulled the target after the first four shots, and all were in one ragged hole. That must have jinked it, because the rest of the group was nowhere near that good. But I'm optimistic that the ammo, and my skills, will improve enough to do better with practice, practice, practice.
