    Why did this happen? 2 ammos, same zero.

    The answer maybe that the target was only 25 yards away, but here's how it went. I zeroed the rifle with this ammo Winchester M-22 Ammo 22 Long Rifle 40 Grain Black Plated Lead Round then I changed ammo to subsonic WINCHESTER SUBSONIC HOLLOW POINT (50 PACK) After changing to the...

    How does shooting angle effect ballistics?

    That cosine indicator is nice. I don't know what I was thinking about the scope mounted indicators. I think I just imagined it up spontaneously.

    How does shooting angle effect ballistics?

    What great channel thank you. I have a mildot master and a leica 1600b which has the angle thing on there. Why not use the angle indicator mounted to the scope? What is a cosine indicator? After reading the manual to it, it seems that I need to learn some other stuff first before learning...

    How does shooting angle effect ballistics?

    I'm guessing when your shooting upwards the bullet is going to drop more from crosshairs, and the opposite shooting downwards. I know you can plug the angle into a ballistic calculator, but is there another way to do it with a scope with some equations?

    Advanced Marksmanship What conditions defeat a laser range finder?

    Not what I was expecting, but I suppose that is a valid response. What do mean by lateral displacement to front focal plane?

    Advanced Marksmanship What conditions defeat a laser range finder?

    Some obvious ones to me are snow, rain. How about fog, mirage, or soft objects? I read for soft objects you can lrf a nearby hard object instead.

    Help me with MOA

    I'm still confused, why would I want one of those? A Spotting scope makes sense to me though.

    Help me with MOA

    455pt or 40x? What are you talking about? Are those spotting scopes? I have a leica range finder.

    Mil value changes with range? How do you use it?

    I was visualizing the problem wrong. I'm a noob super star. So what do learn next, dope or mildot master?

    Mil value changes with range? How do you use it?

    I thought the aim point and the target point were .3 away from each other. If you had to dial up .3, wouldn't the target be around 3 low, and the aim point be at 3.3? So you would have to adjust up .3 so the aim point = the target? Speaking of which, how can you tell if it's + or - mils? Like...

    Advanced Marksmanship My Mil formula for distance in yards

    what is subtension?

    Mil value changes with range? How do you use it?

    I did the equation to get 3.03 mils, and your dope was 3.3. I don't understand dopes yet, but if your dope is higher than the answer, wouldn't you dial down .3? Or is it up?

    Help me with MOA

    I went with the RF instead of a better scope. I kind of drool at the vortex ii scope that can zoom out to 27, but my swfa 5-20 can get the job done right. I need to start learning about dopes.

    Help me with MOA

    On another thread I started talking about this subject more. If you have a guessed size of an object you are firing at, you still will not use the translated mil value of inches. You plug in the estimated height into the equation, measure the height of the object in mils and that will give a...

    Mil value changes with range? How do you use it?

    I'm trying to figure this one out. So you would put the inches and yards into the equation which would give you the mils. Now the top of the mil value would have been the bottom of the target which is 60 inches above? Or was the center of the target at the top of the mil value? Point of aim is...

    New 10/22 Tactical Trainer stock by RTAC

    Can't you just make mine then send it to me as a gift? Then I could donate an amount you would find reasonable for the work you've done?

    Mil value changes with range? How do you use it?

    I know a few things about the kestrel. I know it can get most of the environmental measurements I need to plug into the ballistics calculator it has onboard, and even blue tooth it to a smart phone (that I don't have personally) for ballistic applications. Some other cools stuff I have is a...

    Mil value changes with range? How do you use it?

    Seems like you need to know the inches part only if you are doing range estimation with known size. Also is appears possible to tell the size of something if you have a known distance. I have the kestrel 4500v with applied ballistics coming in the mail, how can that (I want to say thing) tool...

    Mil value changes with range? How do you use it?

    I thought knowing the inches per mil at a given range would be good for corrections. Or does it really matter to know? I mean I read somewhere that if you miss, you can just use the POA as the cross hair.

    Help me with MOA

    After watching the first video on the mildot class I posted earlier, I think it's possible to estimate a target's size using the mil dots. In the first video you see this triangle where 1 mil = 3.6" at 100 yards, 7.2" at 200 yards etc. Say you see a target 100 yards out which looked 1/2 mil...
