I have one of these rifles and am working at getting it shooting nice tight groups and was wondering why the information on bullet weights to shoot say not to use anything over 150gr but regulary found post about people using heavier bullets,

I'm confused :confused::confused::confused::confused::confused:

Is it safe to use the heavy bullets or not.
 
Isn't there stickies for stuff like this? I would normally say use search but it rarely works well here.

To the best of my understanding nothing heavier than 168grain, unless your rifle is specifically tuned by a gunsmith for anything heavier.

Yes your rifle will fire and cycle heavier ammunition but it will put excessive wear on components. There have been threads indicating that the bolt will smash into the back of the receiver so hard as to make it crack and split away.

So nothing heavier than 168 grain.
 
The M14 is descended from the M1 Garand, and the Garand had a well documented history of problems with heavy bullets due to its long, skinny op rod that was prone to buckling.

The M14 doesn't not have the same op rod, but the recommendations against heavy bullets remain. How much of this is fact and how much is blind carryover from the Garand, I have never been able to decide.
 
Nothing more than 180 gr. Is my rule. Mine shoots the best with 168gr. Try some different loads. A buddies shoots 150 the best. Each rifle likes diffrent ammo.
 
I'm a lover of the 125 grain and 130 grain weights of bullets! Hey, it's cheaper and I'm only shooting inside 500m :eek:

So why beat up your op rod ? :D
 
i hunt with the 168 ballistic tip, but i think i might try lite bullets Hungry said
 
i can speak from experience with the real thing, and i've had troubles feeding the lighter bullets- i go with 147 minimum and 168 max- most of the time it's 165-168- i use ww748 and when i was using 130 grain , it wouldn't cycle- really wierd- even when i upped the powder charge, it wouldn't cycle as in short stroke, then when you did add the extra powder to compenste ( lighter bullets take more powder for faster vel) you ran into PRESSURE SIGNS ( sooted primers, head swells) almost immediately- in other words, the M14 JUST PLAIN DIDN'T LIKE THEM- and this was ACROSS 4 RIFLES- so i went back to a minimum 150 - the reason i use 165/168 is because they GROUP BETTER in MY RIFLESand i'm all about tighter groups
 
was thinking a drop and go load with blc-2 and the lighter smk might be worth a try
 
I mostly go to the range to watch the casing get ejected from the rifle and I'm less concerned about it I'm hitting within a certain distance. As long as I hit what I'm pointing at I'm happy. Now we just need real 20rounders so I can see how many casings I can get into the air at a time!
