Looks like the BC of a typical 22 long rifle would likely be between .150 and .200, but I don't yet know how to incorporate BC into the formulae. Still researching...cbr600 wrote: What BC did you use? What's your calculated velocity at 100 yards and 1000 yards?

Re: Mystery Bullet In Rowlett
It looks like you are missing a factor or two. Remember that air resistance is significant (BC is Ballistic coefficient BTW) it appears that your formulae would only apply in a vacuum.
The path of a projectile fired in our atmosphere does not describe the perfect arc your program predicts ...

Re: Mystery Bullet In Rowlett
What BC did you use?
I assume you mean bullet caliiber. For this example, lacking the facts, I used 1300 fps initial velocity.
What's your calculated velocity at 100 yards and 1000 yards?
I did not calculate velocity.
HP calculator formulae:
range = initial velocity sqared / gravity ...

Re: Carry in a grocery store that sells alcohol???
If an establishment obtains 51% or more of their income from the sale of alcohol for on site consumption they may have a 51% license; they may not. You would need to view the license certificate which should be posted in a conspicuous place. If it says Sign = RED then it is a 51% establishment ...

It seems we always hear about bad instructors and classes. I want to put in a good word for the class I took

The one thing, however, that he did not mention and I wish he had, was that veteran's paid a reduced fee. I didn't know that until after I'd paid. I suppose that's not strictly considered course material, but I could have saved a few bucks if I'd known about that.

The day I received my pin the status was 'processing application'. Of course, it was about three weeks from the date that DPS received my application before I received my pin. See my signature block.
