Hi from Nova Scotia

Hey guys. Thought I'd register after spending some time getting some great info from the site here. I'm new to Airguns, about 6 weeks in and am addicted already. I've been mostly hunting on permissible lands and documenting my new adventures with a video series.

While I'm here if I could ask a trigger question. I have a Beeman Sportsman RS2 purchsed from Canadian Tire and although it's just a stock trigger, I see it's adjustable with a screw but am unsure of what it does exactly. I haven't found any info on the Beeman site and don't want to mess with it if I don't know what I'm doing. Any tips? Thanks in advance!
