failure to feed

I just got an SAI M1A NM in february. Have shoot 160 rounds so far, reloads. Yesterday I had 2 failure to feed. Loaded 5 rounds in a 10 round mag. 3rd round the bullet tip hung on the feed ramp, thus holding the bolt open. Pulled op rod back pushed round back and let go of op rod and it chambered fine. Did the same thing on another 5 round. These are 150 gr. FMJ bullets. Any ideas? Also, how often should I take a nation match out of the bedded stock for cleaning and lubricating?
Thanks Jeff

Did you disassemble, clean and grease before you fired it the first time??? If not try doing that before you head back to the range. Grease sliding parts, (op-rod and channels it rides in, under the bolt, top of hammer), and oil on the rotating parts (like the trigger and safety pins). Use any good grease and oil, but remember, a little goes a long way. Since it's NM, you need to leave it in the stock as much as possible but you'll need to take it out every now and then. Most guys I talk to who have NMs, take them out about once a year for full cleaning or repairs. At the top of the M14 forum, check out the Tony Ben sticky for disassembly, cleaning and assembly. Hope this helps. -Lloyd

Clean the Gun. Make sure the Mag is properly seated. Use good Ammo and don't ride the Op rod ( I don't think you did but anyway...)and all bad thing will than go away.

Thanks from unkola

What brand magazines are you using? I trust USGI and CMI only. I've read that Chinese Type 57 magazines are good, but I have zero personal experience with them.

the ammo is my reloads. 150gr. FMJ seated to 2.80. Mag is the SAI 10 round. Have not shot it yet with CMI 20 round mag. the gun is lubed per Tony Bens videos. so far this has only happened twice in 160 rounds. The bullet tip hits the feed ramp and sticks there.
Thanks for the input.

Thanks from unkola

Has it ever done it with factory ammo, like Federal?

Any new M1A needs to have a box of Federal M1A 168 OTM run thru it. (It has a picture of an M1A Socom on the box).

This load is 43 grains of 4064 under a 168 grain match bullet. It was specifically designed to function accurately and reliably in an M1A.

If this load works fine, your rifle is fine.

I suspect your recipe is too light. The bolt isn't coming rearward enough to get full strength from the recoil spring.

thanks for all the input. My loads are on the light side. I made them for cheap plinking rounds. 40 gr. H4895 150 gr FMJ LC brass, chrono at 2590 fps 10 feet from muz. They are very accurate for plinking rounds. They shot 2 moa or less at 100 yds. and I can hit a 6 inch plate at 200 every shot. I loaded some 168gr. SMK with 41.5 gr IMR 4895 they shot good but the primer pockets were slightly flattened. Which from what I have read should be similar to Federal GMM. I am still working on that load. Did not have any failure to feed with them, but I only shot 20. I will up the charge by .5gr on the plinking round and see if that helps.

The M1A/M14 has a very narrow operating band-too light a load and it will short cycle, too heavy and it beats the piss out of the operating system. Check the ammo threads on here for your best load levels that work. With the right powder and load level you can shoot anything from 125gr. up to 175gr safely.
