Where can I get a .22 scoring plug with a .17 shank?
+1 on Hughes,great product . I just received one in the mail today,very impressed.some of the best so far and certifiable are from Hughes Precision https://hughesprecision.com/product...6-caliber-scoring-instruction-sheet-included/
The custom brass gauges endorsed by USARB are precision machined by Michael Aber, and are available for purchase from him upon request at cost of $15 each plus $5 for shipping. To contact Mike, you should email: michaelaber@xxxxxxx.com. These custom gauges have proven to be significantly more effective a tool for scoring .177 caliber holes, than other gauges better suited to scoring .20 and .22 caliber holes, which are available from Hughes Precision and Champion's Choice.
and i did not know Mike was selling his brass ones, i have both his and Hughesi 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...
