I’m considering having a 6.5x47 caliber barrel cut for my present rifle. The rifle has a Defiance action and a Manners stock. I already have .308, 6BR and .223 barrels for this rifle. I’m tired of the recoil of the .308 so I thought about the 6.5x47 for my 1,000 yard barrel. I had a RPR in 6.5 Creedmoor with a 26” Krieger barrel which shot well but was not as accurate as my Defiance rifle. I have access to a 31” Krieger blank to use to make the 6.5x47 which has an 8:1 twist. I would most likely shoot the Berger Hybrid Target 140 grain bullet and will test the Berger 144 grain Long Range Hybrid Target bullet. My question to the forum is how long would you recommend cutting the barrel? My .223 and 6BR barrels are Krieger barrels and cut to 29.5”. The .308 is a Hawk Hill barrel and cut to 29”. All 3 barrels shoot lights out in my F Class matches. I shoot F Class matches at 200, 600 and 1,000 yards. If it matters, I’m shooting these matches with a JoyPod bipod but do have a new SEB NEO that I could use for FO class. Would greatly appreciate your input. Thanks!
