Anyone ever done one? Got a donar, thinking 18 1/2".... no turrets,hint.....
I've had several 22" pumps over the years. Owned an 18.5" carbine for the last 30yrs so I've tried them all.
The best length for these rifles is 20" for handling.
A 760/7600 in 9.3x62 with a 20" barrel sounds like a well balanced, feng shui, match of rifle and cartridge. I don't know if a 286 grain .366" bullet will kill any better than a 130 grain .277" bullet, but there isn't any arguing that it would be 2.2 times as heavy upon impact.
