No groups. rounds all over the place. slightly better with gas off.I replaced the op rod spring and Sadlak spring guide. Did way way better with 168grain burger and 42.5 RE15. groups slightly larger than 2 inches at 100 meters. Have a hunch I can get better with some more research. Will try IMR 4895 when I can find it in stock. until then I am putting the rifle away as powder is not available right now.
All of the Chinese ammo went bang. Had one round out of 40 that failed to extract as it swelled in the chamber and had to pound on the extractor handle to get it out of the chamber with a hunk of log I found at the range. One round that I examined had a split neck. Did not look at every case after shooting as they are steel? and I just let my bones fly. I have only experienced a split neck in a commercial brass case once. I have been reloading for about 10 years now for everything from 22/250 up to 375H&H and 338/378 Weatherby and mucho calibers between.
Now I have previously been reloading commercial 308 Win in my Norenc. No split necks, no hard extraction,no incipient case head separation. I check each piece of bras for case head problems before reloading. I am on number 6 reloads for some of my 308 Win. I also do not use a small base die for resizing. I only neck size and I have a shell holder that sets my shoulders back about .002 when using a full length resizing die. Any comments? lets hear some opinions on experience with Norenco ammo and M14 Norenco. I could be wrong here can only describe what I experienced today on the range.

I have been using the surplus norc stuff for a while now, down to about 375 out of the 1000 round crate, and have never had an issue, as it stands now i get 2.5-3 inch groups at 100 yards and thats just fine for me, I wasnt expecting a precision rig when I got it nor was I expecting amazing groups with the ammo, its military surplus ball ammo and when you really look at it, and the rifle does just what it was expected to do, when the real m14s were being used back in the day, 3 moa at 100 yards was standard. for me this rifle is just for fun plinking, Tho later I intend to build a precision rig for sure.

How long ago did U purchase your last batch of Norenco ammo for M14. Have a hunch I might have got some that might not have the same quality control yours had? no way to prove it of course.
 
It has to be at least a year ago. The date is stamped on the casing. I do belive mine ia stamped "96" or "92" i will have a look when i get home let you know for sure.
 
Also i got minr from canadammo. Tho i really dont think it makes a difference on where you got it from. It all "should" be the same. But then again the difference from one norc rifle and another from the same batch can be quite surprising.
