    For the past few weeks I have been out confirming and reconfirming my drop chart for a shoot where I will be responsible on targets out to 1k.
    I have enjoyed doing this so much.
    I am shooting on steel that is placed 100 yards apart from 200 yards to 1200 yards.
    I start at 500 yards after I get the close drops confirmed the first time, as anything closer is sort of boring.
    Here is some thoughts from the different times out.
    The first date posted was the first time to shoot at these targets and getting a sense of the lay of the land.

    How many of you spend time confirming drops?

    He has some 7", 8", 10" and 12" circle targets and then some square ones.
    Using my center-grip XP-100, chambered in 7mm SAUM, with 162 A-Max's @ 2759 fps.
    Shooting was prone off of a bi-pod.
    Optic is Leupold's Mark 4 FFP 6.5-20 with Holland's ART reticle.
    I started at 300 yards and made all first shot connections except at two distances. I missed at 1200 yards (wind) and at 800.
    Had a weird wind going on at 800. Found out later there was a stream bed that was fooling me.
    My main goal was to confirm my drops for the International Tactical Riflemans Championship.
    Most pleasing shot of the morning was at 1100 yards, where I made a center hit-first shot.
    Target is a 7" circle.
    I plan to go out a couple more times and make sure everything is fine tuned.
    Match is 3 weeks from today.

    Went out again today. Wind and mirage was not nearly as friendly.
    In other words-more misses.
    I was able to see the impact difference between sunny and cloudy though.
    There will be a POI change from cloudy to sunny or sunny to cloudy.
    Feeling pretty confident out to 700 even with goofy wind.
    Did okay at 1K too.
    I was spotting for myself, so that was more challenging, as I cannot get back on target to see impacts when I miss.
    I knew I was hitting at 1k, but couldn't see where because of the mirage. I assumed I didn't have enough wind. Corrected for more wind then shot one more time. When I went down range, my first two shots were perfect for wind (more vertical than I wanted though) and my third one was toward the left edge.

    Went out again with the the 7SAUM this morning.
    No misses (100 yard increments, starting at 500 yards) until I got to 1000.
    Then I missed multiple times. Wind was swirling, changing directions, letting off etc. With the target being a little larger than MOA, it can humble you quickly--And It Did!

    Moved to 1100 and 1200 and did just fine.
    Started back at 500, on again.
    Then I jumped to 1K and made 2 hits in succession.
    The weirdness of wind.
    From the shooting position today we had wind from four distant angles while we were shooting.

    Here is a picture of the specialty handgun I am using.

    What is the eye relief on that scope?

    I don't remember off-hand, but I see a full FOV most of the time, even on 20x.
    It looks dangerous with a specialty handgun, but with the proper set-up (emphasis great muzzle brake!) it is not dangerous.
    Here is an article I wrote about it: http://www.handgunhunt.com/promo/me...d=12&title=Rifle Scopes On Specialty Handguns

    Here is a video:
    Look how little it moves back: http://drop.io/8ctxa6l/asset/video-2010-07-31-14-04-45-3gp?ref=yahoo

    Even in my 7mm Dakota XP--200 grain Wildcats at 2700fps.
    Holland's new Radial brake is what I am using in both XP's (video clip):

    I was about to say good job, and then I saw that you are using a handgun.. so I will say, GREAT job... What's the muzzle blast like on that thing? ;-)

    muzzle blast is not so bad for the shooter, but if someone is beside me they will get buffeted:D
    When you are spotting though and directly behind me, it is not an issue.

    Most of the time, I am not at regular range, or in a line of shooters.
    When I am, it is usually with a group who is also using brakes.
    So in essence, we deal with the blast.

    I have found that if you can concentrate when being buffeted, it just makes you a better shooter, as you can stay focused amidst noise and concussion.

    I wouldn't say I enjoy it, but now I see it as a means to better myself in the midst of distraction:)
