I have had Jim Kobe in Bloomington MN build a number of custom guns for me, the last was a 375 Ruger that I intend to use in Africa but I think it would do outstanding work on Grizzlies also. His phone number is 952.884.6031, I am away from home and do not have his email with me.
Jim has always done outstanding work in a timely fashion at a good price.
