I have a Timney trigger on a R700. Suddenly went from the factory set 2.5# to 5#. Noticed this when squeezing off on a nice Antelope buck. The first time I ever had trouble with a Timney. I have several. I checked it later and it seemed fine. Then started noticing varied pull weights. Took it off reinstalled it and readjusted it myself. Ran a cleaner lube through it first. Ran the weght adjustment screw in and out then set it at 2.5". Before it varied 1.3#-5+. Now 2-3.5#. Tried to get a hold of Timney but got sent to a recording. No return call. Sent an email and got a responce in 2 days. We can send an RMA. I accepted. No responce 2 days later. This could take awhile. Covid?
