mybrainhurts 23 Posted November 13, 2013 Report Share Posted November 13, 2013 Just bought a weihrauch hw77 .22 but I need to lower its power as its shooting over 12ftlb with a heavy pellet , just wondering if I bought a weihrauch service kit would the mainspring be under 12ftlb ??? On a bit of a tight budget with Christmas round the corner so don't fancy paying a gunsmiths price , if I have to I will Quote Link to post

Lewis Ste 245 Posted November 13, 2013 Report Share Posted November 13, 2013 Stripping a hw rifle isn't very hard and see if it's got any packers or washers in and take these out first and check the power then if not then take a coil off don't be doing both and dropping the power to low Quote Link to post
