It appears that our new member Klinkers has developed a handy ballistics calculator available on line. (see The first topic in this topic section for the link.)
It is my intention to begin this post for discussing questions, suggestions and comments concerning this program with its author. Mostly because I have a bunch of questions that someone else might also have.
It is not my intention to bash or argue about any points of this site. If you don't have constructive input please don't put IT in here. If you find something that you dissagree with politely make your point and let it rest. Klinkers was nice enough to share this with us. His site asks for suggestions and comments.
I have taken a brief look at the site and I would like to start with a few questions.
1. Elevation as it relates to the sight relationship to the gun. I guess I dont understand what this is all about. At first I thought it meant altitude. It became obvious that this was not right. Then I thought it meant the distance from the center of the bore to the center of the scope. I'm not sure if this is right. Could you please explain what "elevation" means exactly on this site. I looked in the glossary and this did not clear it up for me.
2. When calculating recoil, what does the "velocity" window represent? Is this the theoretical rearward velocity of the gun if it were mounted to a weightless carriage rolling on frictionless bearings? Is it measured in feet per second?
3. If I set the maximum range at 2000 yards I get a message that the maximum incremental drop is exceeded. What does this mean?
4. How do I know which drag function to choose?
5. Are the 3 windows under "B.C." and "Vmax" so that we can enter the BC for the given bullet at different velocities like those given on the Sierra bullets website? If not then what do they do and what does "Vmax" mean?
Now I have one suggestion. It would be nice for us knob crankers to be able to see our come ups in "MOA+ clicks" instead of just clicks. By this I mean if my come ups for X distance is 14 clicks and my scope has 4 clicks per MOA I would like to see 3+2 (or 3MOA plus two more clicks) if my come ups are 49 clicks the column would show "12+1". This saves doing the math wrong because at 1000 yards 7 clicks is a 23 inch miss. 27+3 is alot easyier to crank in than 111 clicks.
Lastly a comment. On your site you say "You will find on most if not all american made scope that the reticle is magnified as power is adjusted."
I'm not sure this is quite accurate. I have owned Leupolds and Weavers and Bushnell and Tascos. As a gun store clerk I have sold many other brands and I can only think of one scope that had a reticle that grew as the magnification increased. I'm sure there are more but I don't think it is most and it is certainly not all. Unless you mean something different.
Klinkers I know I didn't ask you if you wanted to have this post so if you don't want to handle questions like this say the word and I'm sure we can get one of the moderators will nuke the whole post. /ubbthreads/images/graemlins/wink.gif
