Before I passed the family heirloom 1886 Winchester down to my daughter a few years ago, I loaded all sorts of bullets into NEW 45/70 Winchester brass...

@jerry-attrick You can get the 392 HEMI in a Wrangler these days, but I can't imagine WHY anybody would want one. 470 Horsepower doesn't make any sens...

Very cool! A significant upgrade over the "old" version. Now if we could get the USGS, BOR, etc. data into the database. Loyal?ÿ

I've been playing around with all of this data for a few days now, and I find it quite interesting. Although I have seen somewhat similar situations f...

Even a blind squirrel finds a nut once and a while.

Little treats like the one below, can come in handy at times (1016 CRTHG), the second BM on the list (bottom of page 28 in Bulletin 889, I'm sure that...

Yo Sacred Cow, don't forget this one... Ya never know what you might find. Loyal
