Dont have time to start load work up on new 308 rifle so ordered two boxes of federal 150 grn so i could at least shoot it . thought federal loaded with sierra bullets , been a long time since i bought factory ammo but these round are loaded with a soft point that has a cannelure . any one know what it is ? looks like a speer mag tip maybe ? seems like i read or saw on web speer cci and federal were somehow connected ?
