Re: Flatness of trajectory
Worth noting -
The "new" Exbal PDA program gives you an option to input the target height in the Ballistic Retical Analysis screen and then will calculate the near and far range in yards that each Tic mark on your specific reticle is actually zeroed for.
The older Exbal program will tell you how many inches high or low you would be if using each of the Tic marks based on the target distance you enter... I actually prefer this way of looking at the solution myself, although as pointed out, the other has its inherant advantage as well.
If you're a little bit limited on elevation dialing, or just prefer to use an R2 reticle or other BDC type reticle, and knowing you've got to dial some oddball number like 20.88 MOA to hold on a target at 1048 yards is made much easier than holding the 20 MOA Tic mark .38 over POA if you instantly know the POI will be just about 8" low if holding right on the Tic itself... Not hard to hold 8" high and just use the 20 MOA Tic mark now. On the other hand, if you think holding on a Tic mark that's kind of close, but not nearly perfect and it may be too far off, then punch it up and see it only amounts to and inch or two at what ever range, that's what I also find very useful about it.
Nice to see on the new program how far off you can be in yards though and still keep the shot within so many predetermined inches of POA (with a rig that shoots one holers that is), especially if you're ranging a bush, rock, or what have you that's just close to the animal or path/area one might show up at.
I'll stick with a high BC bullet myself, I need all the help with cheatin wind way out there that I can get, up closer I'm less concerned with as my rangfinder is spot on and work well all the time... out far's where I run into the major error stacking and wind issues.
My wife seems to think the "Danger Space" is still much, much, too big, at any range, as I still can't convince her to set up a chair and hang out next to my target to relay back to me each POI via walki-talki! [img]images/icons/grin.gif[/img]
