I must disagree I am a pretty high volume shooter. Some people can shoot those stocks and some can't. Usually people just come away with the opinion that "I just can't shoot a SXS. My shooting with a SXS really improved when I got something that fit. Caveat I have unusual dimensions. I will NEVER have a target O/U that does not have an adjustable comb.

I must admit that I have never tried the "BRASS RING" approach.
