do shotgun barrels wear to the point of replacing? Is that why you log her shooting?
They can "wear out" but it's very, very unusual,
with her semi I was really tracking for cleaning purposes but turned into a good info base on amount of shells we were shooting,
with her O/U, by that point my OCD had kicked in and since she shoots better than me I can't really give advice or critique so I focus on documenting so I can show here numbers,
since Sept 1 she's shot
60 rounds of skeet, 90% 20ga with a few 28ga and .410 mix in
28 rounds of trap
on skeet she misses #5 low house 65% of the time and in skeet there are a total of 24 "normal" shots, on your first miss you get to shoot it again (your miss still counts as a miss), if you don't miss any you shoot the last station #8 low house twice instead of once, for a total of 25
surprisingly enough we've found out she misses her "option" shot 65% of the time also
it's a lot like boating, somebody may say "I've put xx hours on the boat in the last few years" when in reality it's a lot more or less than their perception.
I do keep a spread sheet on the boat with the YDS for my hours, every piece of maintenance I do and additional parts/supplies (I've spent $7,600. in toys/supplies/fixing (not counting oil/filters).
