where to get .17-.22 scoring plugs?

I recommend

A plug with a magnifier from either ARA or IR 50/50. Both ate alike. and the magnifier makes all the difference.

Scoring Plugs/Gauges

The custom brass .177/.224 gauges endorsed by USARB are precision machined by Michael Aber, and are available for purchase from me upon request at cost of $15 each plus $5 for shipping. Contact me at email: michaelaber@xxxxxxx.com. These custom gauges have proven to be significantly more effective for scoring .177 caliber holes

The solid brass scoring plugs are made to a tolerance of... 0.224" +0 -0.0005" on the scoring ring and the insertion probe is 0.179" +0, -0.001

OK, i guess the board was slow again to give an answer. :)
if you were to search some of the airgun forums this has been discussed on a cpl of them.
and here is one of my answers on one.
i have been checking with other makers of the scoring plugs and most of them say the same thing
they do NOT meet the specifications on the Rimfire and Air Rifle Benchrest Federation page ? http://www.wrabf.com/Scoring Guide.htm
but one maker does say they meet the specifications
Hughes Precision products says this plug is .190 insertion spindle/shank and a .224 visual flange TARGET SCORING GAUGE .22 (.223/5.56) Caliber.

I didn't know it. I had to email the board. I posted the answer here because it's obviously not widely know to posters here. Or anywhere else for that matter. Makes me wonder about the viability of this sport...

The plug program is prominently shown on the home page of the USARB. The sport is quite viable. https://www.usairriflebenchrest.com
