Re: Getting in to Long range rifle competition.
Actually, you're in a good area for this. Williamsport is the original 1000 yard benchrest club, and will be a good resource for you, even if you don't want to try BR. It's worth the drive to get to talk to the guys there and make contacts with the 'smiths in your area. Beyond that, take a look at some of the Palma or LR matches, as F-Class shoots are frequently held in conjunction with these. I just came back from Raton, NM and the Spirit of America match. Palma match, but they had several firing points for F-Class competitors on the line, and they fired concurrently with the other shooters in the match. Call the NRA, or look them up on line (the competitions division will have all the info you need here) for matches, dates, and the persons to contact for each.
Good luck, and welcome to the game!
