Have a couple of questions today. Been using a Federal 7/8oz #71/2 load for years in a 21/2 chamber they show on box 1165fps. Is this to high preasure for this gun? They also read 67mm on the box and measure 2.62in. Also looking for a Smith gunsmith near the Bham, Al. area as I would like to get the stock glassbead. I have never done this before but may try it myself as you can get a kit to do this. I am no smith but I have made tools to work on this gun and work the flat spring back in. How do I post pics?Thanks Tommy
