Inner ten oops

Not ISSF. 50ft in U.S. I understand some folks in Europe shoot 15 meter smallbore indoors, which is close to 50 ft. (15.24 meters) Almost all of our clubs shoot paper, and scoring i.t.'s on soft paper is a bit of a chore.

Expanding pellets?

The rifling is extremely fine, so there would be little size change from head to skirt. The paper is another matter. On good paper, Edelmann or Kruger, the grain of the paper will extend inward from the hole. You can lift a pellet by the skirt. On US paper, the holes are not so clean. In either case...

Inner tens

My bad, thinking of another target. Air rifle looks OK, no change.

Electronic and paper innter tens

Gary Anderson told is that at the ISSF B class a few weeks back. However, using the Air Pistol outward gauge inside the 7 ring requires a 10.4 for an i.t., whereas the old rule, inward gauge covering the dot, only needs a 10.3 At least it treats everyone the same. The USA-50 target has similar probl...

Electronic target scoring

The small dot in the middle (air and USA-50) is not really used. The rules call for outward scoring, with the gauge inside or just touching the 8 ring. The inner dot is used for scoring inner tens, sometimes. All acoustic electronic targets base their score on the center of impact, not the edge of t...

Noise bounce

Most of the sound comes from the muzzle of the gun, with some from the ejection port. It is close to a 'point source'. You also get sound off the trap, less of an issue outdoors. If you only had to worry about the source, the gun itself, it wouldn't be that bad. But sound radiates in all directions,...

Websites and WAGs

The old website provider had problems. I worked with them when USAS transferred from the internal database (mine) to the web accessable one. There were problems from the start. It got to the point where the powers that be decided the first provider could not provide what was needed, thus the change....

Noise control ?

Active noise suppression works well in headphones, with a limited "target" area, your ear. Over a large area, like a shooting range, not practical. Egg crate foam is about the only reasonable option.

During the actual shooting part of Rapid Fire, nothing works very well.

Results posting

USA Shooting has switched to a new service provider for some of their website functions. Should not affect results, which seem to appear a day or so after the event. There were about 250 competitors at the WAG match, with two venues as it ran over range capacity. So it may have taken a bit longer to...

Megalink scoring

If you can, please post a printout or link to the output from the target in question. Megalink has received ISSF approval for their 10 meter system, as well as 50 meter. I assume (dangerous) that the scoring accuracy would have been verified. In my experience (Megalink user and tech support for Nort...

ISSF vs USA Shooting plug

Minor point: the ISSF does not have an outward gauge for the 50 ft target as they do not recognise it. USA Shooting has such a gauge, which is NOT the same size as the A-36 outward plug, although close. The NRA has adopted the 50 ft target and will use it for international style competitions startin...

Outcome goals vary from person to person. Making the final, shooting a good score, making the national team are all motivating, for different people. They are the things you want to achieve. They are why you compete. If you focus on them during the competition, you probably won't shoot as well. That...

Goals come in two flavors: Outcome and Process. Outcome goals (like winning the match or shooting a good score) motivate you. And keep you coming back to the range to train. Process goals (like proper shot execution) make outcome goals happen. I don't keep track of score. I think about shooting a te...

Why the formula is several pages long

It gets a little bit worse, because you should consider bullet diameter as well. Sound travels out from the edges of the hole, not the center. For a dead center 10.9, it doesn't matter, anywhere else it makes a differrence. Most electronic target systems measure the temperature in the sound chamber,...

I believe the process is weighted already. Scores fired in the Pan Am year, count more heavily than scores in the year before. and so on. Doesn't really matter if you have only one quota (or none!). As for travel (outside the U.S.), this has gone on for years. There is a clearly specified procedure ...

Electronic target calibration

I don't think the targets have any adjustments for this. Any method would be a verification rather than calibration. We have used the black paper roll to verify shot placement. Can't do it with just one shot, but it does work for a series of shots. Almost all the target mfr's use acoustic detection ...

Depends on the match: NRA International rules follow ISSF, usually with a year or two lag, so the 25 mm rule applies. Up to the match sponsor as to which rulebook applies to the particular match. I've never shot a match that wasn't NRA International, USAS or ISSF. Like front aperture size, this coul...

Rule 7.4.3.7 allows a maximum front sight diameter of 25 mm for air rifle, so the 22mm globe is legal. I don' have an old rule book, but I think that is a change in the last quad. May have happened at the same time the higher riser block (up to 60 mm from center of barrel to center of sight) rule we...

For air rifle, ISSF limits you to the 'normal' 18 mm globe. Free/Sporter have more flexibility. I use the 22mm with a tube, to get a similar sight picture to the 18 on a standard barrel. I would not use the big guy without a tube, you won't see much around it. Light reaching your aiming eye is mostl...

I cannot comment on IPSC, never shot or coached it. International rifle, mostly. I have seen a wide variety of strategies that worked (if we define success as winning medals at the national/international level). One common factor was persistence. Refusing to give up. Beyond that, I can't say as I ha...
