25Y .22 scoring gauges

[iainfm]

Hi,

I've just discovered the gauge I bought from the NSRA shop a year ago is for 25M not 25Y 😒 so I'm on the hunt for an oversized official/regulation 25Y one please.

I'm (probably) going to be taking on some scoring duties, so I'd also be interested in any graduated gauges for tiebreaks etc.

Thanks in advance,

Iain

@iainfm You “should” be able to get a 25 yard gauge from the NSRA, it is a very basic item and I would have thought they would be able to supply one. As for graduated gauges they have all but disappeared from use. IIRC there is only one occasion mentioned in the NSRA Rules where they are used*. Some local and county leagues still mention them in their regulations but as far as I’m aware, graduated gauge sets haven’t been produced for years. Anyone who has a set is likely to be holding onto them.

*5.5.5.5.6 At the National Meeting only: where there is an unbreakable tie having used all the other tie breaking rules and the decision decides the presentation of a trophy, graduated gauges will be used to decide winner.

I believe this rule dates from 2002 which explains the scarcity of graduated gauges today.

Thanks for that. The NSRA shop seems to be offline at the moment for anything except targets.

I found the gauge dimensions etc in the NSRA rule book, so it wouldn't be beyond the realms of possibility to make some. Annoyingly I was offered, but turned down, a lovely metalworking lathe a few months ago by someone who has since passed away. The number of things since then where a lathe would have solved my problems is unbelievable 😔

I also have a notion to make an electronic gauge, a bit like the TargetScan app, but on a computer. I've still to figure out the best way to build it though.

I've been trying to contact the NSRA about a 25 yard gauge, emailed Bisley and Aldersley, called both but so far nothing heard back

A lathe if you can use it must be a wonderful thing to own!

I would try the competitions department and explain your problem. You could then remind them of:

5.1.2 Only plug scoring gauges as offered for sale by the NSRA are officially recognised

Then offer to manufacture your own if they can't come up with a solution.

Electronic "gauging" is nothing new, the 156 DISAG RM IV target scoring machine or its predecessors have been around for 40 years. A few years ago, I saw a method that employed a flat bed scanner to produce an image that could be emailed and then scored by software. I seem to recall that the issue was achieving a satisfactory standard and quality of image rather than the scoring process. However in these days of EST, is it worth the effort?

I had an update from the LRC this morning, they do have 25 yards gauges in stock

Thanks for letting me know. I've emailed them so hopefully they'll get back to me.

I have been thinking about alternatives though (while conscious that only nsra ones can be used for nsra competitions, I'm unlikely to be scoring these any time soon). 

Ideas so far are to knock them up in a cad package and get them machined in China. I've not priced this yet but I'd imaging getting a few would work out pretty cheap. 

The other thought was that 5mm brass rods and 12-13-14mm discs are easily available. Add one to the other, and turn it down to suit. The ~80° angle of the disc as per the regs would be the trickiest part. But 90 is approximately 80, right? 😁

Having said all that, they emailed right back so I've ordered one. Thanks all!

Maybe they're watching this forum 🤣

The 80 degree angle is only specified for Air Rifle and Pistol, no mention of a similar specification for smallbore rifle.
