270 ACKLEY IMPROVED
This is a custom rifle built on a Remington 700 action. It has a Shilen stainless steel, # 4 fluted barrel finished at 25 inches. It was installed in a McMillan Remington classic synthetic stock. All metal parts were Teflon coated and the stock was painted black. A Jewel trigger, and a Leupold 2.5 – 8 X scope in Leupold mounts and bases was installed. We decided to stick to only the premium hunting bullets for this rifle, sacrificing some accuracy for bullet penetration. Several people used this rifle on several African safaris, bagging well over 100 big game animals, including all the larger plains game such as sable, zebra, kudu and waterbuck. Most were shot using the Barnes X 130-grain bullet, although some were shot with the Trophy Bonded 140 grain Bear Claw. Both bullets performed without a single failure.
Winchester brass and Federal 210 primers were used. All groups are 3 shots at 100 yards.
