ISSF pistol specs?

Kramer

Quick one for the ISSF guys (& gals :cool:).

.22lr "Olympic" specifications. What are they? i.e. barrel length, distance between sights, sight type, revolver/pistol, ammo (subsonic/high velocity, solid/hollow point etc.) permissable etc.
Not looking for a 100 page .pdf document, just the basics. Would a 20 shot, 3" barrelled .22lr/.22wmr pistol be considered suitable for "olympic" shooting? What about a 7.5" barrelled .22 WMR revolver?

:cool:

Full ISSF rulebook (new for 2009) is on the web for free here. You're looking for the pistol specification table on pages 337 and 338, the end of the pistol chapter.

Here are some examples of the usual ISSF stuff:


Barrel Length up to 153mm and sight radius up to 220mm for 25m .22 pistol, unrestricted for 50m.
Sight type is ordinary open iron sights only - no red dots, no telescopics.
Revolvers are allowed, so are normal semi-autos, but loaded with 5 rounds only for 25m and 1 round only for 50m.
For 25m, no compensators, muzzle brakes, perforated barrels or anything along those lines is allowed (which includes silencers).
The pistol has to fit in the measuring box, which is 300x150x50mm in size. It has to fit in it; beyond that there's no rule as to arranging it in the box.
Max weight of the pistol is 1400g for 25m pistol, and 1000g is the minimum trigger pull (no such restrictions in 50m pistol)
As to ammo, no high power or magnum loads for the centrefire stuff, calibre from .30 to .38 (7.62 to 9.65mm, inclusive); and for the smallbore stuff, it's standard .22lr ammo, minimum velocity 250m/s measured 2m from the muzzle (chronographs are meant to be available on the range for shooters) and minimum bullet weight of 39gr.

So basicly, the barrel length on the WMR revolver is too long and the WMR bit is a problem. But most .22 pistols and a lot of the fullbores would qualify.

Pistol Type|Weight|Trigger|Measuring Box|Barrel Length|Sight Radius
10m Air Pistol|1500g|500g|420x200x50|Box size|Box size
50m Pistol|No restriction|NR|NR|NR|NR
25m rimfire Pistol|1400g|1000g|300x150x50|153mm|220mm
25m centre fire|1400g|1360g*|300x150x50|153mm|220mm

*to be reduced to 1000g in new rules

For air pistols: May only be loaded with one (1) pellet. Ported barrels and perforated barrel attachments are allowed.

For 50m pistol: May only be loaded with one (1) cartridge. Hand covers will be permitted, providing they do not cover the wrist. Special grips are permitted.

For rimfire and centrefire 25m pistols: Compensators, muzzle brakes, perforated barrels or any device(s) functioning in a similar manner are not allowed.

Other restrictions:
a) 10 m Air Pistol Grips: No part of the grip, frame or accessories may touch any part of the wrist. The heel rest must extend at an angle of not less than 90 degrees to the grip. This applies to the heel rest in front and behind the grip as well as on the sides. Any upward curvature of the heel and/or thumb rest and/or a downward curvature of the side opposite the thumb is prohibited. The thumb rest must allow free upward movement of the thumb. The grip must not encircle the hand. Curved surfaces on the grips or frame, including the heel and/or thumb rest, in the longitudinal direction of the pistol are permitted.

b) 25 m Pistol Grips: Note a) applies. In addition, the rear part of the frame or grip which rests on top of the hand between the thumb and the forefinger, must not be longer than 30 mm. This distance is measured at a right angle to the extended center line of the bore.

c) The weight of the pistol is measured with all accessories, including balancing weights and unloaded magazine.

d) Measuring Box: The pistol is measured with all accessories in place. A manufacturing tolerance of the rectangular Measuring Box of 0.0 mm to + 1.0 mm in each dimension is permitted.

Quick replies :eek:. Thanks guys.

Now, that "measuring box" specification: what if I made one from very flimsy plastic & was able to shoehorn an (oversized by ISSF standards apparently ) 6.5" barrelled revolver into it..........would that be OK?
I'm talking VERY flimsy plastic BTW .

Reckon I'll have to get out my trusty Dremel & get cutting before next August :D.
Looks like the 3" barrelled pistol's OK though (will fit in the box) but might be slightly disadvantaged in terms of proper olympic competition.

Minister Ahern, you're a bad man, a very, very bad man .

You'd be diddled when you went to any national level match Kramer, our measuring boxes aren't flimsy
But you could give it a try with just about any .22lr pistol really. All you need is a paper target and 25m between you and it on the range. (And the backstop behind it, obviously ).
The specifics of what you can and can't use don't come into it up until you get to the national level (or club matches for the clubs that are more serious about competitions!).

The 3" barrell might put you at an awful disadvantage though - RRPC couldn't get the P22 to even hit the card reliably at 25m from a benchrest, let alone hold the centre of the target, and it's barrel is longer than 3" if I remember right.

It'd probably fit anyway, the box is quite big. But might I draw your attention to the maximum barrel length of 153mm?

We had a benchrest pistol competition recently and as far as I remember the first four places were all taken by ISSF pistols. They were followed closely by Hammerli X-esses and Browning Buckmarks which are very competitive at that level.

Having said that, I've seen competitions won by Buckmarks, so bring it on
