Need help in reloading 223

[wc12]

I just got my new dies for 223. I loaded three blanks (bullet and brass only) to try on my AR. My OAL is 2.24 and crimped it. When I loaded them on my AR for the function test, the bolt gets stuck and takes a few pulling of the charging handle to eject the bullet, what could be the problem? The ar functioned fine with the factory ammo.

Assuming this is once fired brass...My guess is you did not resize the case neck as well as push the shoulder back properly/completely. Please ensure you read and reread a reloading manual before going too much further.. Calipers are your friend

You haven't bumped back(resized) the shoulders of the cases enough. Turn your sizing die in another 1/4 turn or so and try it again. You'll have to keep trying by trial and error if you aren't using a case gauge to set your dies up properly.

Lookup "shoulder bump" in reloading. Lots of info on the net.

Also make sure you leave a small space between (about the thickness of two nickels) the seating die and the shell holder so you don't crimp the case necks and deform the shoulders.

Most of the time, chambering issues are from not F/L resizing enough.

Improper/lacking re-size like mentioned above. If the ammo came from the exact firearm, it should be ok due to being fire formed. Fire formed brass can be neck re-sized to extend case life, just don't try to shoot in any other weapon...could cause a major jam.

you have a auto loader & the main thing with them is functioning . Adjust your die to kiss your shell holder so it cams over with a little preasure. This way you get complete sizeing, assuming you have a full length or small base die.

thanks for the advises. I'm gonna try to resize again.

Sounds like everyone is in agreement. Brass is not fully/completely resized. Base of the brass hasn't been completely resized so its hanging up in the rifle.

I would suggest getting a case gauge and using that when adjusting your sizing die. Makes it a lot easier than adjusting die and re-chambering until it chambers and ejects smoothly.

I had the same issue when I started loading for .223

I will get a case gage. Thanks for the quick response everyone.
