    Sure, I'll cop to asking some questions that kinda stir the pot, but all answers have helped me this last week.

    I noted that Kolar Arms offers barrel bedding services. This is a procedure that, as I understand it, is done mostly with rifles to allow barrel vibrations to be consistent from shot to shot. Some rifle stocks have contemporary "pillar" beds which merely hold the barrel in a secure manner so that the barrel does not touch the stock. I have a rifle stock or two that uses pillars; I have relieved one of those stocks a bit so the barrel does not touch it and torque the two allen screws down using a torque wrench for evening some of the stress in theory.

    So, question, does mitigating against inconsistent barrel vibrations, whipping, etc., upon firing, in a target trapgun, particularly a shotgun used for long distance shooting, improve patterns and/or create more consistent points of impact. I have read about an engineer, Mr. Seahase, who claimed that using a secret electrical process helped change the grain structure of barrel steel to allow better patterns. Allegedly, this was not just snake oil. And, of course, some riflemen that shoot long distances have barrels relieved of stress via cryogenic processes; cryogenics have been used, as far as I recall, for a long time with certain parts in race cars to strengthen parts, e.g. ring and pinions and spider gears.

    I dunno where the "literature" is; I just saw the alluded to service at the Kolar website.

    Thanks in advance.....and I hope I'm not just stirring the pot, but sure hope to read informative and passionate answers.

    I looked at the Kolar website and didn't see anything about barrel bedding. I also Googled shotgun barrel bedding and didn't get any hits. That's got to tell you something. I have never heard of it being done. Mark

    What kolar is referring to is glass bedding the forend to the iron, not the forend to the barrel. It just makes for a tighter fit b/w the wood and metal and prevents cracking, it has no performance advantage.

    Yep, if you seen Gun fitters thread of the stock he did on that beautiful Krieghoff, you could see in that stage where he used the glass bedding on the receiver. That relieves the stress points and makes the pressure even throughout the metal to wood connection. It also makes for a perfect fit to the point that there is no gap between the wood and metal anywhere. Looks much better. As you can see in the pictures. The fit is perfect. Maybe Joe will clarify this, as to his procedure.

    Also click on the link above and see the whole process. Joe goes one step further and adds a dowl in the stock for added strength.

    Glass bedding a rifle is for a different purpose. Obviously accuracy is more important with a single projectile. Jon
