Serious Black Powder Shooting?

[.22-5-40]

Hello, everyone.  In reading the old notes and records of some of the old-time black powder marksmen around the end of the 19th century, they mention the recording of temp., humidity, and barometric pressure, during their shooting.  Does anyone still practice this?  Thanks.

Yes. The guys that shoot creedmoor and long range gong matches need to keep very good notes and do a lot of testing to insure that bullet goes where it's intended way on out there. These things are also important for silhouette shooters, but since that only goes to 500M things are quite a bit easier to deal with.

Thuer, add wind velocity, direction and cloud cover.  Most folks I read don't barometric pressure now a days.  I get the pressures for the day from weather websites.
I carry 2 instruments in my range box:  one for temperature and RH, plus an anemometer that records multiple reading ...

Here are multiple range charts you might want to copy and record on when shooting various distances ... http://www.longrangebpcr.com/FiringLineForms.htm

I try and keep a good set of notes for mid and long range muzzle loading (we compete out to 1200 yards here in the UK). A good 'database' of sight settings along with prevailing atmospheric conditions should enable you to find the target quickly.
