Hi Been lurking on this sight for a long time. Finally got up the funds to buy my new Rifle. It a Cooper 6.5x284 M52 Excalibur, 24" barrel with a NightForce 5x22x56 scope with MOAR reticle. Med NightForce rings on Warne Bases. Gun with scope weighs in right at 10lbs. I Been working up a load and the best one to date is pictured. 4 shots within the size of a dime, thats a good start. I have learned a great deal from this site "Thanks You" Virgin Lapua Brass Fed 210 primers 51.5 gr of 4831sc Powder. I started at 48gr and worked up slowly, please do the same 140 gr Berger Hunting VLD bullet at 3.155" OAL chronoed at 2665fps but that seem a bit slow. will verify during drop tests. Coming from a 300RUM you gotta love the lack of recoil with this caliber. One question, will my groups get better using fire formed brass???
