Why does everyone chop their barrels to an even number length?

I bobbed a 300WM to 21 3/8 while living in AK (and dropped it into a Bansner)... Does that count?

21" 7PRC I determine length based on ballistics and how it will carry with suppressor/folding stock/on pack hiking in, etc.

I think the most vocal guys make it seem more prevalent than it is. Much like many rifle parts.

For me I will never own another rifle with a barrel over 18 inches as soon as I buy one it goes to Kampfield to get cut
