I just bought a Bergara B14 R 22 steel barreled action to put in the Foundation I run my 6x47 Impact in as well. I had to grind down the trigger hanger pins a little to fit the stock, but not a big deal. The Bergara 22 aics mag does not want to latch into the Hawkins m5 bottom metal. I will probably see if I can buy an extra mag catch and file one down. Before I do I was curious if anyone has used the Bergara barreled action in other stock or chassis and if you can successfully run Vudoo or Rim X mags in the Bergara if it is not in the factory stock?
