Reply To: Brocock Elite Contour S6 takedown and rebuild
To Spysir: It is possible that I got a bad barrel, but I don’t think so for the seating depth. The design of the action does not permit a longer probe than my replacement. Also, the beginning of the barrel sits only about 0.100″ from the air supply hole from the air tube below it. The barrel does not have a hole it like most other PCP designs. For this Brocock, there is a small air chamber between the end of the bolt (excluding the probe tip) and the beginning of the barrel. The air supply hole is between these 2 points.
I did some further testing today, and the “honey moon” accuracy has declined somewhat. I shot JSBs 13.43s, 15.89s and today 18.13s, and the 18.13s won hands down. I think this is because the pellet is filled with more lead inside and the probe seats it deeper. Even with the 18.13, I estimate about .025″ of the pellet’s skirt is not seated yet.
More later. Thanks for reading my article.
