Local range used to do pin shoots in the 80s
And, yes, it is fun! The plastic coating on th epins makes them very tough, but they will crack and shatter when hit with something of suitable power.
And 9mm isn't it!
Our shoots were as follows: 3x5' table, 5 pins, spotted about 2" from the front edge of the table. (Major caliber). 7 pins, spotted down the center of the table (minor caliber-9mm/.38spl). And 5 or 7 pins spotted 2" from the back edge of the table for .22LR class.
Guns divided into 3 classes, auto, DA revolver, SA revolver, and Major, Minor, and .22LR.
NO FMJ AMMO ALLOWED!!!!!!!
Started with gun at low ready, touching the rail, and time ran until the last pin cleared the table. No limit on number of shots, or reload, time ran until the last pin cleared the table.
Pins would usually last for 3 to 5 runs against .45acp, before they were too badly cracked to stand up on the table. Less against larger rounds.
A 250gr SWC .45 Colt @ 1100fps throws them off the table with authority!
A 240gr JHP .44 Auto Mag throws them off the table and breaks them into two or three pieces!
I never finished better than 3rd in SA revolver (7.02sec), and never even placed in major with my .44 AMP, although at 5.36sec, and 4 shattered pins, I was happy!
