What do you guys use for hunting ammo for your M14/M305 rifles? I have just been using Winchester Super X 150 grain .308 rounds and they seem to work fine for the few shots a year I take with them.
It is my understanding when using sporting cartridges in the M305 one should install a Sadlak grooved gas piston to handle the extra gas pressure. This includes sporting bullet weights of 150g which are close to NATO weights of 147g. This is to reduce strain on the op rod and receiver. M305 NATO SPEC. cartridge walls are thicker and have a SMALLER powder charge. This is because the automatic action is so fast the brass is extracted before it fully contracts in the chamber after firing. The thicker brass prevents case head separation. Comments anyone?
I had 7 rifles at last countbull#### - just someone trying to sell you a sadlak piston- I use 168 grainers all the time and have used 180 on occasion when the need arises- ie elk moose ,and bear- best ask barney or dennis or 45 acp king what he thinks - as far as head separation goes , it's a matter of the chambering- ie headspace- every time you fire the case expands and contracts and that's where the stretching comes in- that's why we use the 4 or less and gone rule in the m14 et al
Mine handles the Federal hunting ammo without problem. I mostly use the lighter, but have on occasion shot the 180 grain.
Federal blue box 150gr soft points, shoot well,

yea, you keep telling yourself that- and glen zediker , ( who has done far more testing than the rest of us put together) the other big three that are on this board are wrong-as far as f/a goes , it's the same story as the fn- they're designed for 3-5 shot bursts, not true full auto- why do you think we learned sonofa*ich repeat in the armyyou got that right, the heavier bullets and higher charges have bent op rods. the extraction can be so quick and violent that the case rim can be bent. the m14 was designed around the 147 gr. nato round, and to have full auto mode.
