Reading an article in my new mag about Daniel defenses new DMP 5.56 .sweet looking rifle a 1 to 7 riffling freefloated handguards . The odd thing was the three types of Ammo they chose was odd ,a federal 52g , Hornady 53g and a remmmington 55g . They boasted the whole article about shooting the heavy stuff and-then they chose these ? They claim they shot a .73 .88 and a .97 . Even odder ,the 52 grain was the .73 . A 52 grain in a 1to 7 twist ? I'm getting mine out tomorrow and trying that. Don't think it will be promising.
