The pin loads need to be "crafted" for the particular type of match you are shooting. Some indoor matches set up the pins on a flat table closer to the back for different calibers,
.22, on the back,
9mm, 2ft from the back,
full power .45, etc-pinguns the regular 4ft from the back.
For the regular pin matches using either tiered tables or flat tables the prevailing opinion of the top shooters is that you need a power factor of 195 or higher. bullet weight x velocity(200gr bullet going 980fps).
In .45 caliber the general loads are
[email protected], 230 or 235gr bullets at 900fps, 200 at 1000fps, etc.
10mm- 155jhp @ 1350, 180 @ 1200+
Revolver shooters use the 230 "pinbuster" from R&R bullets @900fps. It is thought by many to be the best revolver combo,period. Of course .45acp, .45colt, and 44mags also work, but dont need to be loaded to elmer keith velocities to talk pins.
As you can see, most of the top pin shooters shoot either one of these cartridges at these power levels to take pins off the table with even a marginal hit at a match when you are pushing the envelope.
As far as a 9mm load, I would use a 147gr bullet with a slow burning powder, and realize that it will work when the pins are closer to the back of the table, but not well for a standard pin set 4ft from the back. Hope some of this helps, DC
