You are living within 2-3 hr driving distances of two of the best clubs to start learning lr shooting. You will find some of the best LR shooters in the US at both of those clubs.
just NE or Raleigh off I85 you have Camp Butner where they shoot F class every month. They just had a clinic this weekend on how to shoot and read the wind. go to www.long-range.com/forums
and read a little on Fclass. There is a link there to the NC club that shoots at Butner (www.northstateshootingclub.com
), just ask under the Fclass forum.
Second you have the NC 1000 yard BR club at N. Wilkesboro. They have a factory class you can shoot in also. If you want to shoot the 270, try the 150 gr bullets. www.nc1000ydshooters.com
The Fclass has a FTR class (308 or 223) and that is where I would suggest you start.
All you need to shoot Fclass is a bipod and scope with target knobs.
Go and watch both before you decide what to do and how. You will find from 3-5 participants at each that are premier smiths and will tell you what you may want to do once you decide.
If you decide to buy a new gun do yourself a favor and go to Vass NC (5 miles north of Southern Pines on Hwy 1 and 30 miles from Fayetteville) to Eds Gunshop. Ed is one of the biggest volume dealers in the US and the cheapest. He normally has used heavy barreled 308s for sale at really good prices.
When you go to Butner, find an old codger named Vernon Harrison (goes by Dot.250 on LR Target shooting forum). He runs a LR shooting course on his farm in S. VA that is premier. He only has 35 yrs as military, and "other" fed agency (3 letter alphabet name that is forbidden to mention) sniper and routinely trains snipers for federal Law Enforcement agencies there. If you decide to get a 308, strongly suggest you listen to him on suggestions for gun and scope.
