Bill recently received a unique request, a father and son rifle build project. Both are customer supplied actions. Sako extractors installed. Both bolts have been fluted and new threaded bolt handles. Manners stocks both painted and bedded by Premier Accuracy. Both have muzzle brakes. Each brake that Bill installs is custom designed for each type of case to maximize efficiency. Both are shooting extremely well. Once these two rifles are completed, both father and son will take one of Bill’s, Premier Accuracy Shooting Schools (P.A.S.S.) to learn how to develop loads and shoot the the absolute best they can.
300Remington Ultra Magnum
Bill really likes the new Leopold scope and it is quite light for a 34mm tube. He tells me the optics are very clear too. The 300RUM caries two rounds in the mag and one in the chamber. The 300 RUM is showing great promise. The original receiver was a 30-06. Bill modified the follower, magazine box and feed well ramps to receive the larger cartridge with out volcanoing. If you do not do this the bigger cartridge will nose up(volcano) and jam the rifle. The customer has requested the new ELDs from Hornady and a few other good bullets in the 180r class. The rifle has a 26in 1:10 twist barrel that is Cerakoted Graphite Black. Bill also Cerakoted the receiver to match a stainless steel finish.
The 7mm RSAUM has been handling every bullet very well. With H4350 and Sierra Game Kings 160gr and every group has been under 3/4in at 100 yards. The scope is quite heavy but the gun weighs just 6.5lbs. Below are some targets. Norma brass is proving to be really great for this cartridge. The barrel is a 24in 1:9 twist and is Cerakoted Graphite Black. The receiver is Cerakoated in a custom Dark Grey.
The barrel is a very light #4 contour with fluting. Again a custom brake has been made for this exact caliber. Bolt is fluted and a new custom threaded bolt handle has been installed too. Action was completely blueprinted. Stock is a light weight sheep hunter stock in Premier Sage.
Update: The 300RUM is not shooting great. Attached is a photo of some of the results.
