cayugad, I fire lapped mine same as back in the old days when I was building Hawken Rifles. It shoots ok I guess
I only have a 2 power scope and it groups less than an inch with the 50/40 200gr.Shock Wave since I fire Lapped.
The thing that bothers me is except with the 50/40's I get a flyer now and then say 8 to 10 shots that will be an inch or a little more out of my group. Lee
