I shoot ten meter Olympic targets in my back yard range. I need maximum shot count and consistent velocity for target shooting only. I have sent for a Lane regulator and have been advised by him that I may wish to install a 25% less powerful valve spring. It is my understanding that the original factory spring is part number CR-054. I got the idea to install the Lane regulator from watching an excellent complete tear down and regulator install by sub12airgunners: https://www.youtube.com/watch?v=iNg2554hOCw. Of course this was on a UK .177 caliber Akela and sub12 got 200 shots from this installation. I hope to maximize my shot count and use primarily Crossman Premier pellets 14.6 grains since I purchased many of these years ago. If any of you have done this install I would appreciate tips since this is my first real tuning modification to an air rifle. I have added a DonnyFL Sumo moderator to help keep my system as backyard friendly as I can. I also put a barrel band on this rifle and attached my bipod to the bottom of this fitting. I shoot low power and just need as much accuracy as possible. I can use advice on how high to set the regulator and other adjustments that may be necessary to balance this install. Thanks in advance for helping me.
