I’m somewhat detail oriented.
i keep data cards for all m Airguns on 5”x7” index cards - a second set of these cards are kept separate from my Airguns for a couple of reasons:
#1) inventory / insurance in the event of loss
#2) quick reference to details in the event I have to break the gun down for repair. allows me to return it to previous excellence
#3) to examine for a ready reference when I’m away from the gun and I am contemplating how to improve its performance.
#4) various dope data with various pellets
i always make 2 cards. One I keep in with the gun in its own little special box and the other in my fireproof safe.
One of the young guys I shoot with keeps his on his phone and in the cloud - I’m old school.
how about you?
