Quilly,
I have a marlin model 25 in a .22 cal rimfire. The trigger on it was very very stiff. I had a gunsmith adjust it for me and he got it down to 3.6 lbs. He said he had to do something to the seer to get it lower. If you do get it worked on, be careful to check if there are any accidental misfires. The first time I went to pick up my gun, he handed it to me and it seemed fine when you cycled the bolt quickly. However, when I cycled the bolt slowly, it would FIRE! So I gave it back to him and he said that he filed to much off of the seer, and he tried again. The second time it came out great, it feels good, no creep and a lot easier to pull the trigger. The gun is a shooter.
