Bullet problem in SR1911?

I just bought a ruger SR1911 a few days ago. I haven't had time to shot it yet, but I noticed that after loading a bullet in the chamber after a few times it starts to move the bullet back into the case. Any ideas why this is?

Re: Bullet problem in SR1911?

If you are continually loading the same round by chambering then ejecting and putting the round on top of the mag the bullet may have loosened from the casing. What brand ammo is it. Through work we shoot lots of rounds using Federal jhp. Was not uncommon to find once chambered, unfired rounds that had the bullet push back in slightly. I know some guys who go ahead and shoot them. I personally don't as I'm unsure how much more pressure it can create. Someone who reloads may be able to give some clarification on that. So to answer the question I would say it is more likely the ammunition than your gun. Weak seating on the ammo vs tight tolerances in a nice new gun.

It can increase pressure and if the bullet is pushed too deep the pressure can be excessive.

There are two ways to be fooled. One is to believe what isn't true; the other is to refuse to believe what is true.

Re: Bullet problem in SR1911?

I assume you are able to notice the difference in seating depth just by looking at the round...as apposed to using a caliper to measure it. If it is that noticeable, you should not shoot the round. I reload for an SR1911 and don't have that problem with mine.
Does the slide close all the way? If I don't get a good taper crimp on a round, the round will not go all the way into the chamber and the slide will be stuck open a little bit. Try some different ammo and see if it continues.

Does the bullet have any markings on the tip that would suggest it is hitting something inside the chamber? If so, I would talk to Ruger.

The brand of ammo I am using is federal. The slide does close on its own, and from what I can tell the bullets don't have any marks on them.

Federal is a good brand. Can you post a picture of the bad round and a good round beside it? Might give some clues if we can see the rounds.

Re: Bullet problem in SR1911?

I'm not sure how to post a picture but according to the caliber it's eighty thousandths off of a new round

Re: Bullet problem in SR1911?

What is the actual COL of the bad round and one of the good rounds?

PAturkeyhnter, the COL of a bad round is 1.135, and a good round is 1.210

Re: Bullet problem in SR1911?

The 1.135 is an acceptable length, according to my Lee Manual, with an 185gr jacketed bullet and about 15 different powders. Since you don't know what powder is used in the round, I would dispose of the bad round and try another box of ammo. If the problem continues, contact Ruger and see if they have any ideas.
Sorry couldn't help with figuring this one out...
Once you get this worked out, you are going to love the SR1911. It is the smoothest gun I have...best trigger, eats all the ammo I put through it and is very accurate.
Good luck beard collector!!!
