Yes, the pressure or altimeter setting as it is known to pilots is calculated at each airport that makes such reports. Otherwise, if you pulled up a town that had no official weather reporting, the pressure would be an estimate using surrounding station data. Most weather apps will tell you the altimeter for a specific location. I use The Weather Channel app for an un-official source of weather information.

Yes, a METAR is the official current condition report that pilots use.
The pressure (altimeter setting) you get from these sources is not the actual pressure at the station. It is actually representative of what the barometric pressure would be at sea level given the barometric conditions at the station. For example, if the pressure is reported as 29.92" at Lincoln, the ACTUAL pressure would be approximately 28.72" since the Lincoln airport is about 1,200ft. Sounds goofy, but there is an important reason for this in aviation.
My assumption is that the ballistic calculators will use the common pressure read from most weather sources.

If anyone is interested in attending a similar style match here's one in Missouri I ran across.

A package showed up today from Redding Reloading Equipment. They have generously donated two 50% off gift certificates to the SAPPRC prize table!!
More info on Redding:

I use Redding comp dies for .308, and they are definitely among the best, IMO. As near as I can tell, these gift certificates are for 50% off of an order of unlimited size. We also have a 8" Rifle Gong donated by www.nebraskacoyote.com, and a $100 gift certificate from Centrolutions/MWTS. More prizes are on the way, from companies like Nightforce Optics and Run-N-Iron Customizing. And don't worry, some prizes will be saved for "tough luck."
On a separate note, I was out on the main match area last week, the wind was so strong that I had to anchor down the spotting scope. I Kestrel'ed the wind at the firing point at up to 35mph, full value. Be ready for it!

Very nice. I also use Redding dies for .308. Good stuff.

You actually gave me pretty good idea this weekend.
No pistol targets will inherently be worth points (and you still have to hit them all), but there may, or may not, be an opportunity to get *bonus* points on some pistol stuff. (Not gear related)
