This will take quite a bit of time, so bear with me...
1st of all, the targets used in the anglosaxon world (more or less standard for LR work) have a 5-ring as max score, with an x-ring inside that, which is called V-bull.
When you shoot and are scored, the number of V-bull is noted, so a 60.03 would be a score of 60 (out of a possible max. of 75), with 3 V-bulls.  In LR shooting, MLAIC rules are not used, so it is not the best 10 out of 13, or whatever.  
For LR work, you shoot 15 shots for score, each shot having a potential max. score of 5 ( so the max. score is 75).  
BUT you also have  - as a rule - 5 ranging shots, to get on target and 5 sighters to get good sight settings for the range and conditions.  The 1st shot hitting the target will be your 1st sighter.
You can usually convert your sighters to scoring shots in the reverse firing order, i.e. you can convert the last shot, or the last 2, 3,... - or all 5.  However, you won't be allowed to convert the 1st 3, and not the last 2 (reverse firing order, remember?)
And as to spotting your shots, actually nobody is able to see them with their spotting scopes - but there's markers in the butts which will both indicate score and fall of shot on the target.  Sometimes these are 'dedicated' markers, sometimes it is just other shooters that aren't shooting in the current detail, so your turn will be next...
 

Belgmart can you take a look at this link and tell me if it�s anyone the target used long range you mean ( five rings , v-bull , etc ) ??

Okay Gents is it 5 ranging shots �and 5 sighter or unlimited ranging and 5 sighters?
 

FWIW,  I only have experience with the HBSA and The WLRHSA matches, so those are all the reference points I have...  Suffice to say, getting on target at 1,000 isn't as easy as it seems at 1st glance!  LR shooting is at the same time a very satisfying but also sometimes an extremely frustrating sport - like getting off the target during your string, and trying to get back on...

600?  Now, that's midrange!  And where in/near Madrid might that be?  In Januari, would be rather cold, no?

Unless you have the modern luxury of electronic target scoring you will most likely require a butt marker to pull target frames up and down, mark shot placement and signal score. Shot placement is simple indicated by placing a 'pin' through the shot hole - the pin itself holding a piece of flourescent orange card which the shooter can see with the aid of a spotting telescope. See the MLAIC rules refered to above for signals etc used.
 
Some competitions shooters share duties with marking while in others paid markers are employed. It really depends on your renage facilities.

Yes, you need a marker for each shot so that the shooter can see the plot fall. It is also usual to have 2 or 3 shooters share one target, so one will fire while the others are loading. After the shot is fired, the next shooter will take his turn. So you could have say 5 targets, but 15 shooters in the same detail. For this reason each shot is scored and recorded.
 
I realise all this sounds somewhat complicated if you don't have experience of it, but things do (generally) run smoothly!

( I�m thinking that when I will suggest that kind of things over here next June they will shut me in a mental hospital !!! HAHAHA )

An alternative that is used in International matches and nowadys also with the MLAGB is to have a score keep allocated to each target. So....
 
Rifleman 1 fires while rifleman 2 is loading
Butt marker scores target
Score keeper on firing point agrees score with rifleman and records it
Rifleman 2 fires while rifleman 1 is loading
Butt marker scores target
Score keeper on firing point agrees score with rifleman and records it
Rifleman 1 fires while rifleman 2 is loading
Butt marker scores target
Score keeper on firing point agrees score with rifleman and records it
....etc....
 
The person manning the target never needs know who is shooting.
 
This also works with 3 people to a firing point. Those at Bisley are wide enough for 3 shooters (and 4 at a squeeze) to leave matts scopes etc. on the firing point. Other ranges may have different constraints.
 
 
Come over to Bisley next sping and shoot with the MLAGB as a guest (or join) and see how easy things run. We already have shooters from France, Holland and sometimes USA who have joined the MLAGB and shoot with us.
 
David

Overseas shooters have been coming by car ferry. Powder can be obtained here in the UK. The MLAGB can arrange for the necessary paperwork for firearms and a temporary permit.  
 
David

I will be over there for sure.. if my wife doesn�t kill me when I suggest the idea !!!
David , do you know when in spring , more or less ?

Provisionally (and still subject to confirmation) we have:
April 6 MLAGB National 300 yard Free & Enfield Rifle Championship, Bisley
May 4 MLAGB National 500 yard Free & Enfield Rifle Championship, Bisley
 
These are both Sundays and there are more shoots later at 600, 900 and 1000 yards. There will also be some shooting on the Saturday with the Long Range Rifles Branch of the MLAGB. The full calender will be available on the MLAGB around christmas.
 
Email of PM me via this forum and we can sort details, as much notice as possible to ensure your entry and arrange paperwork. I will be able to arrange for you to shoot as a guest. You will notice above that we also shoot Enfield rifles at long range!
 
Bisley is on the west side of London and Heathrow airport is fairly near. Have at look at the National Shooting Centre web site.
