I just got started in air guns last year. I've fished and hunted all my life. (up till now) I have a skin condition that turns to cancer (melanoma) if I stay in the sun too long. I've had to give up everything else, but I can sit in the shade and shoot my air rifles. I have "10" of them at this time, and two of them are Marauders, one in .177, and one in .22. I have a set up on my patio and keep the starlings and sparrows thinned out. I do hand loading for my long guns, and have been doing my own work for over 40 years now. I am retired, 71, and still going strong. I get my air fill at a Scuba shop, which is another thing that I had to give up.

Thanks, and good shooting,
