The XBR target stock was kept as original. The non XBR rifles are housed in a Stockeys’ LRT aluminum blocked stock and fitted with a Stockeys’ stainless Obendorph trigger guard and floor plate. The XBR bull barrel which was originally chambered for 22-250 was set back to accept the 22x47 and was kept at 1:14 twist. I then hand honed the bolt to where it was a smooth tight fit and had a gunsmith true the action. All except the XBR (which has a trued action/bolt) were fitted with a PTG oversize one-piece stainless bolt with small firing pin and pinned Sako extractor. Two of the rifles started out with donor Remington 700 short actions and a Rem 40 XBR action. The rationale was all three can be formed from the 6.5x47 Lapua case without having to fireform. A primary driving factor was the availability of Lapua brass, case neck length (which allows seating longer bullets out farther), the cartridge has a good reputation for accuracy and works in a magazine if desired.Īfter that initial endeavor I built a 6x47 and a 22x47Lapua. I originally started out building a 600 yard F class rifle and after considerable research decided on the 6.5x47 Lapua cartridge.
