Fair enough. I have been known to rag on pretty well anybody, just not
constantly.

I have to grant the truthfulness of this to you JF.

I had not thought you inhabited dodge city. All but gun nuts tend to use
magazine (mag) and clip semi-interchangeably. Heard of "banana clips"
holding 50 rounds or more? Not arguing about precise military
