    Thatís ok I went back to first match this year, scored them myself, and would have scored considerably higher according to WRABF guidelines for scoring, but in the relm of things everyone was scored by same person so itís all relative? Besides on a national scale Iíd just get my butt handed to me! Lifes good...

    Well we just started shooting BR at my club, and I looked at all the gadgets for measuring holes and decided that what we are going to use is another pellet shot from the same gun.

    It's unfortunate that (to my knowledge) BR targets aren't available in the same cross-grain paper (Kruger and Edelman) used for 10 meter Olympic air pistol that cuts (almost) perfect holes with wadcutter pellets. Sure, it won't be perfect with a round-nose, but it would never rip or tear and be as good as we can get, no backer needed.

    At 10 Meters most pellet guns designed for 10M and other guns with more power will hit the target perpendicular for practical purposes...If you shoot a wadcutter at this distance then the hole will be almost perfect...At 25 Meters no pellet is going to hit the target perpendicular and if you add WIND to the equation, the holes can and will vary in shape.

    Using another pellet for gauging is not the way to do it and then consider that BR is shot with .177, .20 and .22 calibers...The scoring ring has to be .22 or the shooter of a .177 will be in disadvantage vs. another shooter using .20 or .22 calibers.

    Your best alternative is to use the OFFICIAL HOMOLOGATED plug for BR or machine one yourself...The USARB site has mnore info about these plugs but essentially It has a shaft of .184" and the scoring ring is .22...These plugs will fit the .177 hole tight and will be very accurate...Not even the Orion system will be as accurate as an official BR plug and the one and only more accurate scoring system would be an Olympic ASUS or a similar machine where the impacts are measured with a combination of laser beams and acoustic microphones and you can use these systems with paper or no paper...Look at thee systems and you will see that the the paper target has a hole in the Black section, nevertheless you can also use full paper targets.

    AZ,

    You are right. I didn't consider that .177 and .22 shooting at the same time would give the advantage to the .22 if scoring only by pellet size. Using a .22 for .177, .20, and .22 will make things fair. In addition, you probably just added a few points and X's to targets I've already shot if I go back and rescore them with a .22.

    Thank you!

    One problem though. If .177 and .22 are shooting together, then ALL of the .177 shooters shots need to be measured as .22 to be equal and fair. That's just not doable in a match.

    I must've missed something when I tried to explain the plugs and scoring..It is DOABLE and it is done everywhere...You only require 3 different plugs for scoring any of the 3 calibers.
    The .177 USARB scoring plugs have a .184 shaft to make sure they fit tight in the .177 pellet hole but the scoring ring measures .22...The .20 plug also fits tight in the hole and has a .22 scoring ring...The .22 plug has similar characteristics....Since all plugs have a .22 scoring ring, no caliber has an advantage over the others...

    Get and use a perfectly leveled scoring board so the plugs are perpendicular to the targets/pellet holes...Otherwise the scoring may not be correct

    AZ,

    Your tip has certainly improved my scores! I was scoring my targets by their .177 holes, but although I don't a pro tool yet, I found a rod with a perfect .223" diameter and carefully resized all of the .177 holes to .22, using calipers to be sure the diameters were correct. Beside making the holes much more concentric and easier to judge, my 225 jumped to a 234-2X, and my 230 jumped to a 237-3X. It feels almost like cheating to see these huge holes in the paper, large enough to almost take out the 9 ring at .31459", but rules are rules. Thank you so much!

    I just bought a .177 scoring plug for our club from Hughes Precision. I don't know if it's the best, but I'm sure it will do the job. It was only $8.50 with free shipping. Thanks for all the advice.

    Wish I had had that information earlier strever, thank you! Contacted Hughes immediately to make sure I got the right one, but I definitely would have enrolled our club if I had known.

    To cover my bases and make sure I have the proper equipment. I went ahead and joined USARB, and will get those two free gauges and magnifier as well. If nothing else, I can teach someone else to score.
