Butch, the only 6BR you would likely see used in short range BR is mine. It is a Shilen barreled 40X chambered for the original 6BR Remington. I bought the reamers for the 22 and 6 in 1978. I built a few BR's but many more PPC's of course. I use the BR today because I am a bit of a contrarian. To be honest, I have not competed in a short range match for several years and have not fired the BR for three years. It still shoots well though. If Lapua brass had been available in the seventies, the BR might have been a little more common. Forming brass was a chore. I let Cindy Six do the forming back then and bought the formed brass from her. GD
