I have an Ithaca model 200E double barrel in 20 Ga. Barrels are fixed skt / skt. Those worked good for me 20 years ago before I got to be an old man. I could double on a covey within 20 yards. Now that second bird is getting out there to about 30 yards and skt is just to open for that distance.

Who does the best job installing screw in's? And does anyone have any advise?

Thanks
