As others have mentioned, the lack of availability/proximity of high powered ranges, plus the rifle, reloading and accessory equipment expense can be an obstacle for increasing the number of new shooters entering the sport. I'm going on close to 2 years since I started shooting mid-range FTR (no 1000yd ranges within reasonable driving distance for me). Despite it being a 150mi drive each way, I try and shoot every monthly match at my local club (Port Malabar in Central Florida) - If it were closer I'd shoot FTR much more often. I shoot 100yds most other weekends to practice. I'm already in the process of having my 2nd custom 308 rifle put together (approx. $5k/each w/ Sightron Scopes), because I'd like to have 2 identical rifles (1-competion, 1-practice rifle). You add my reloading station, bipod (Joypod), Bags (Protektor), chronograph (Labradar), reloading supplies (lots of Berger Bullets, Lapua Brass, Varget Powder, and CCI Primers!), and other miscellaneous supplies and it gets pricey. Certainly, it can be done a lot cheaper, but it's still pricey if you get hooked! Then there's the time factor - between reloading and shooting every weekend to tune bullets and practice my technique, it takes lots of time that not everyone has available.
Fortunately, I can afford the toys, have the time and can travel to the occasional event to supplement my local shooting. In fact, shooting 1000yd event in a couple of weekends at Butner, NC for the first time! I also try to encourage shooters at my local 100yd range that show interest in longer range shooting whenever possible. However, for many of the reasons listed above, I'm not sure this sport will ever get the mass numbers of participants that other sports do - shame!
