    Second outing with a CZ-455

    First, let me tell you about the first outing. Being that this is my first rifle, I went to the range unprepared.

    I'd set up paper targets at Oak Tree at 50 and 100 yards. 50 yards was cake. Zeroed the scope in 2-3 shots. Checked on repeatability. I was indeed getting consistent hits with good grouping. Moved up to 100 yards, which is when I first realized, I couldn't see my hits through my scope. The black background on the paper targets didn't help either. Not seeing what I was hitting, I didn't get very far learning anything that day.

    Finished off hitting a few of the steel targets. The sound the targets made was sweet, albeit my ability to hit them was 50/50 at 100 yards.

    Fast forward to today, I had MLK day off from the office. I went to Angeles Range and this time I came prepared. I got me some ShootNC reactive targets, 6 inchers and a Redfield 60X spotting scope.

    Started at 50 yards with CCI Standard Velo 40 gr ammo. My zero held from the last session. Hit after hit, my $100 Nikon scope ain't half bad. It's actually pretty good. Then I set up at 100 and 150 yards. Checked the Nikon Spot On ballistic app. It said to put in 14 clicks of elevation, 3.5 minutes. Dialed it in and let er rip. IMPACT! I'm hitting the targets consistently and getting .5-.75 MOA at 100. Raised the rifle to give 150 yards a try. IMPACT! The grouping is spreading out to about 2 inches, but still very consistent. Saweeet!

    I played around a bit going back and forth between 50, 100 and 150 yards. The Nikon P-Rimfire turrets are providing repeatable and consistent adjustments and predictable hits. One downside is that each click is like 1/2 MOA. It's a lower power 2- scope, I think they're almost all like that.

    Then I got ambitious. I set up a target at 200 yards. First shot is a hit. Bullseye! But it was a fluke. Out of 20 shots, I hit the target only 3 times. 1 bullseye and 2 flyers inside the 6 inch target. I seem to be getting a lot of wind drift. Spotting my hits, I see I am stringing 2 inches to the right of the target. I tried to compensate, then I was stringing 3-4 inches to the left. Results were erratic. I'm going to have to learn how to shoot in wind, or how to use windage. Or at least figure out what was wrong (200 too much for 22lr?). I lost interest. I'll save 200 for another day.

    I went back to 50 and 100 yards and loaded up some Lapua Center X ammo. Checked my zero at 50, 3 shots at the bullseye, all touching each other. Nice! I'd learned a little tip off YouTube about natural sight pictures. It said to set up the shot with little no muscle tension to hold the target. This meant adjusting the sand bags and body position meticulously. From my results, it seemed to work good.

    Went to 100. The Nikon Spot On app did not have a default for Lapua Center X. I'd researched it on the interwebs and found some info for B.C. and ballistic. Plugged it into the app, and got a recommendation of 14 clicks of elevation. Took the shot, I'm high. Just got the upper edge of the target. Dialed 2 clicks of down elevation, took the shot, I'm on! Fired a few more rounds of Center X and I'm consistently getting 3 shot groups touching each other at 10 yards

    It was a great day at the range.

    Memo to self - My turret says 1 click is 4" at 50 yards. I'm not sure how true that is. I don't get 4 inches per click even at 100? More like 1.5" per click at 100 yards. Will be looking into it further on the next range day.

    Sounds good...

    .22 LR SV at 200 yards is roughly 8 MOA per 10 MPH of wind at full value -- shooting at a 6" target (3 MOA), gusts as little as 4 MPH average can blow you completely off target. Get a bigger target and a spotting scope, and you'll have an excellent platform to learn wind calls.

    Like we say about scopes, "unless the price tag includes a comma, don't assume the adjustments are as specified." Quite typical to find scopes where one click = 1/3 MOA or 1/5 MOA instead of what it claims. Your scope probably says 1 click = 1/4" at 50 yards, or 1/2 MOA per click, but whatever it says you just never know until you try it. Take good notes.

      Wow, your reply just solved a whole lot of questions for me. A bigger target, gather more dope on my turrets and more knowledge on wind calls. I'm on it. Thanks!

        One other thing...

        Watch out for parallax. After re-reading it looks like you probably have a rimfire scope, which are typically calibrated for 50 yards. When going to 200 yards, unless it has an adjustable objective (so-called "AO"), this can introduce parallax -- any change in your head position away from directly on axis will move the crosshairs over the target.

        Sometimes folks confuse parallax with wind interference, but it's important to correctly diagnose shooting errors. Both wind and parallax are capable of producing errors of 4-8 MOA at 200 meters.

          You are correct. I do have a rimfire scope. I'll need to look more into it then. Thanks!

              Very nice write up! I passed on to Marik. that Nikon also has a PROSTAFF 3-9 Target EFR that has parallax adjustment. Great little scope and one of my favorites. Knowing exact MV from your rifle and scope height makes a big difference when using Nikon's Spot On Program, even when getting the correct number of clicks instead of using a BDC reticle.

                I mounted this AO scope on my 455 Trainer: http://www.presmainc.com/products/details/100036



                Works great. BTW, I called the fliers.
