can anyone out there help me with ajusting my cooper mod. 21 -20.tac. trigger .great rifle benice if had a fiberglass stock

I just picked up a Cooper 20 Tac. and noticed my trigger was a little stiff also.If in doubt may want to give Cooper a call.
If I may ask have you worked up a load yet and if so what powder and bullet? Have you shot any coyote with it yet?
I probobly wont get around to messing with mine until next summer but think it will prove to be an interesting caliber.
