M&P 10 FTF, break-in issues and reloads

[marathonrunner]

yikes! From looking at this thread, it seems .308 on an AR platform is not as reliable as an AR in 5.56 is that correct? also seems .308 in AR platform is much harsher on parts and parts are more prone to breaking.

Simple answer—-Don’t shoot reloads out of a new rifle.

I’d be interested to know if you fixed the issue. I’m having failure to feed issues as well, but it’s on certain factory loads. Remington and Winchester jacketed soft points work fine... federal 7.62 NATO and perfecta not so much. After I use something that has issues, and go back to the stuff that works, that stuff starts acting screwy as well. Also getting a ton of brass shavings in my chamber. I made a separate thread Bout this with pics of the shavings and a more in depth description of the issue. Any help would be greatly appreciated.

I really do not understand "break-in" issues with firearms. Guns are supposedly test fired several times at the factory, right? So, you buy a new firearm, take it home, clean it, lube it, load it up and fire it. It should go BANG! every time. Now, surely over time as parts wear a bit and mate a bit better, the firearm might operate a bit more smoothly. But if it isn't working properly after a clean'n'lube job with decent ammo, then there is something wrong and the factory shouldn't be telling you it requires a few hundred or a thousand rounds through it to work properly.
