Snow day trigger work

Spent the snow day working on the triggers of my CZ 452s. First up was the American, which got the green YoDave shim tube between the sere and the barrel, and the third heaviest spring. Shot a couple of targets with it earlier in the afternoon--not quite a hair trigger, but very, very light and virtually no creep. Pretty impressive, actually.


Came home and did the UltraLux. This one got the thinnest (blue) tube, and although I was going to put on the heaviest spring, it was longer than the factory spring and felt like it would stiffer than the factory spring. So I opted for the #2 spring (second lightest). Got everything back together, shot a couple of targets. Managed the following target offhand, one of my better efforts. The Ultra trigger is not quite as light as the American, but comfortable with the BRNO sights.

Other than falling apart on the fourth bull (I was getting pretty tired at that point), this was pretty good offhand shooting for me with the aperture sights.

You'll see on this first benchrest target where I got stuck after the first three bulls (clockwise from the sighter) just a hair to the right of the x-ring. Messed with the screws, pushed/nudged the windage knob gently but firmly for the next two bulls, finally dialed in on the sixth bull:

I'm pretty pleased so far. Offhand shooting seems easier with these sights, at least for the Ultra -- I've always struggled to shoot the Ultra as well as I shoot the lighter Trainer. The first bench target with the thing dialed in yielded the following results:

That's pretty good for me--I generally can't do that consistently with my scoped American. (and yes, I always seem to fall apart on the third bull . . . don't know exactly why that is. but I usually finish strong.)

enough for now. As soon as I'm done with this post I'm going to attack the sights with some Kroil to loosen things up, and then a good cleaning and oiling.

Finally got the BRNO sights on the UltraLux today, with pictures below. I have to say, the BRNO target sight photos thread on rimfirecentral was very helpful, particularly the photo of the modified screwdriver to seat the nut holding the front sight to the ramp. I did exactly that with a Dremel tool and it worked great, whole thing only took 10-15 minutes.

Took the gun down to the club tonight, but also had Sophia with me trying her new 22 as well, so I only got to shoot a couple of targets with the new sights, but I was in and around the black pretty quickly. Offhand didn't seem to difficult at all, and first three sighters off the bench went into a single hole--that got me pretty cranked up.
