68cal Prototype Breach Test Results

[Frank Pittelli <frank-at-pittelli.com>]

After getting the septic line repaired yesterday, putting the yard back
into reasonable shape, and watching my daughter's soccer team get
trounced, I had some time to work on a 68cal prototype breach. 
Fortunately, things went much better on the firing range ...

The results of my tests and a discussion of the breach design can be
found at:

including a couple of pictures.

In summary, more tests are still needed, but it's cheap and it fires!!
