I just read that Butch shot a .082 group in a BR competition last week in Seymour TX. There’s the proof in the pudding on his rests right there!Butch is to modest to say it but, buy you some kind of cast iron base. Call Butch and tell him what you have and get him to send you one of his shade tree tops. You will have a front rest that won't hold you back and if later you want to upgrade you can sell it for more than you paid.
