I use a Ruger LCR 9mm revolver, but the bullets I had yesterday couldn’t fit into the cylinder,
I'm worried I might wear the cylinder if I continued to do that . I tried some Rem oil but didn't work. It seems to have something with the bullets ( Bronze 9mm luger )which I used now . I originally used Winchester, but I ran out. Thanks.
 
In my experience, Ruger cuts their 9mm chambers pretty tight. I've had trouble with some budget ammo fully chambering in some of my Ruger 9mm offerings. Used to be that when I tried to shoot S&B 9mm in my Ruger P89, I would consistently get 2 or 3 cartridges out of a 50 round box that wouldn't fully chamber. I say 'used to' because I stopped trying to shoot S&B in Ruger pistols years ago so I don't know if it's still an issue.

If you are sure that the ammunition is the proper caliber for the handgun, then you could contact the ammunition maker and let them know you're having an issue. Another option is to see if the ammunition will work in one of your other 9mm firearms.

JohnKSa , I will contact the ammo maker in Texas. PMC Ammunition thanks.
 
If you're shooting factory ammunition, I'd do a thorough cleaning of each cylinder. Then try a couple different brands.
 
After thinking about this I am curious. Are you using the moon clips to load the ammunition? If not the cartridges will not fully go into the cylinder, but will fire according to Ruger and the manual for the LCR. The cylinders must be headspaced to use the moon clip but still hold the cartridge without the moon clip for firing.
Here is an excerpt from their manual on page 18:

Yes, I already knew that , if I want to use the ejector rod to extract , I have to use the moon clips. thanks.
 
Measure the outside diameter of the case from mouth to base on the rounds that won't chamber and see if that is different from those that will.

luck,

Dumb question here:

If you have a set of calipers, what is the case mouth diameter?
(as near to the mouth as you are able)

If so, I can tell you from my experience, they make very good ammunition.

I would take the advice of @cfullgraf above. Try some different rounds from different ammo m

Yes， It was the final step for me to contact the PMC，I don't think they can help me. I will try different ammo first.

I used the set of calipers, I tested 5 good ammo and 5 bad ammo,
they are almost same size, it is just bigger than 83, I am not familiar with this calipers, and haven't used it for long time. thanks.
