Good morning
Imput !!! I enjoy these items.

I have tried several ways into the site. The last I have seen is a cache of the page from 27 June 2011. It shows the ballistics.zip file but I can't access it.

If anyone has it, could you PM me and we could arrange to email it to me.

I just clicked on it, it went right to the page. You need to read down through it, to find the download link.

A nice utility. I use a more complete program from huntingnut.com called Point Blank. You can get it here its free also: http://www.huntingnut.com/pointblank.html

and I see where it has finally been proven that an electrical spark can ignite black powder (but it ain't easy)

I don"t see the spark setting off the blackpowder. I see the spark heating the metal cup that the powder is sitting in to a point were it sets of the powder.

I also got tired of piddling with it so I did this:
Used the following RB ballistic coefficients then ran them through the "simplified JBM calculator" But really it's just an exercise or reality check because of the nature of the ballistics of a sphere. :)

32 cal- .043
36 cal- .049
45 cal- .062
50 cal- .069
54 cal- .075
58 cal- .080

The question was never that electrical spark could not set it off.It was static spark.It is all about
heat.Static spark from ones body just does not have enough amps to make heat to set it off.

The same thing with the stun gun test.If a stun gun burned you they wound not be used by law enforcement.
Volts & amp's are two different things.

Sweet!!!!!!!!!!!!!!!!!!! Thanks for the link

Now it needs just one more column, showing where the projectile sits on the Taylor Scale. LoL

A very nice and useful program. Thanks.

The download worked for me, but wouldn't unzip the file, because my copy of win.rar to unzip it with had exceeded the deadline for having t pay for it. I downloaded Zipgenius, which is free with no apparent snags, and got the program installed and working.

I was only able, possibly due to ignorance, to unzip and install it in the downloads file, but unlike many it works when you simply copy the installed folder into the programs folder.

It is an extremely interesting program. While the amazing long-range exploits of Kentucky rifles in the American Revolution certainly happened, it does show up pretty clearly that they depended either on very exceptional judgment of trajectory and distance, or someone running out of luck.

i got on. a great site, thanks for posting it.

Greetings
Just did a work up using a 4 bore ball out to 50 yards. I have gained a whole lot of respect for those large bore "stoppers".

Greatly appreciated. Works fine with Wine under Linux.
