Good Day.
I recently acquired a Cooey model 78. I cleaned the worst of the rust off the barrel with motor oil and 0000 steel wool. The rifling looks pretty good and I took it to the range at 50 metres and it shot better than I expected. The trigger is quite poor (like hitting a wall that you have to force your way through)
If anyone can suggest any improvement please advise. Thanks
 
I never had a single shot Cooey but on many rifles I've just 'polished' anything that 'rubs' anywhere . . . the sides of the trigger, the pin it pivots on, the sear release point. Just Lightly polish with 1000g wet dry paper to take off any rough patches. Stampings often have raised edges that can drag on whatever they go against. I've done this on pistols 'innerds' as well. And finally I use PTFE grease - Permatex 'Synthetic' at CanTire, abouot $15 or so for a 3-4 oz tube, I forget exactly. Just a very light film, like a match-head spread thinly is all it takes. If there is any 'wiggle' in the trigger, I've 'made' washers from thin plastic containers. That can help, too. I couldn't find anything about the 75-78-82 triggers themselves on YT either.
OH, I forgot to add, maybe a lighter spring there ? As long as it will hold the trigger snugly - bump safe.

No amount of polishing will fix them. They're like a very cheap spring airgun trigger. But the mating surface of where the sear sits and catches in the striker is very aggressive.

Only way of lightening the trigger is with some stoning and reshaping where the sear catches on the striker.

Unless the trigger pin walked off and the trigger is binding, due to being on an angle.

I gotten the trigger down to 1#
