Scoring .30 to .38 or 7.62 to 9.65 mm in ISSF CFP?

Post by IPshooter »

Hello all,

I used to know this, but I can neither dig it out of my old brain nor find the answer in ISSF/USAS rules.

The current rules allow for calibers between 7.62 and 9.65 mm (.30 to .38) to be used in Center Fire Pistol. Most shooters use a .32 or .38. When I fired this event many years ago with a .32 on paper targets, it seemed to me that .32 hits were scored with an overlay that measured the hits as .38. I would assume this was done so that .32 shooters were not disadvantaged by the smaller bullet diameter of the .32.

However, I can find no reference to this in the rules from either USAS or the ISSF. Nor do I see it addressed when firing this event on electronic targets. Is it possible this was only a NRA rule?

Can someone please explain?

TIA

Stan

ISSF rule 6.3.5.1

The measuring edge diameter of the CFP gauge is 9.65mm +0.05/-0.00

It's just the spindle diameter that changes according to calibre.

On electronics the same 9.65 diameter is used.

From the 2016 USA Shooting Rulebooks:

6.3.5.1 25m Center Fire Pistol
Measuring edge diameter: 9.65 mm (+0.05/ -0.00 mm)
Edge thickness: 0.50 mm approximately
Spindle diameter: According to the caliber being used
Spindle length: 10 mm to 15 mm
To be used for: Center Fire Pistol Events

With electronic targets, since the computed shot location is determined from the center of the bullet, there is no need to account for what caliber is being shot. Some systems may have a means of showing the actual bullet diameter on the target, but that would not be used to determine the shot value.

.... and there's no truth to the vicious rumour that I like shiny gauges so clean mine with metal polish and wire wool before each match ;-)

Thank you both. I sailed right past this in both rule books. Getting old sucks!

...but it's better than the alternative.

Not Quite.
Yes, the EST will calculate the centre of the shot; but half the (nominal) projectile diameter is then subtracted to determine the shot value in relation to the scoring rings (i.e. 2.8mm for .22 rimfire and 4.825mm for CF).

Good job too! or else they would soon be undersize.

I obviously wouldn't do that, but do like to give my trigger weights a nice fresh coat of paint occasionally ;-)

With a special stock of lead-based paint, or would that be telling? ;-)
