| I am full length sizing my LC brass and some of it is still having a tough time chambering. They are being cut to .3.90". Is annealing the answer or is something else going on? |
|
I made a mistake cleaning an AR-15 one time and some crud ended up in the chamber in the shoulder area. I just for the life of me could not get a round to got to battery. Found out when I ejected the round that there was some carbon that was caked on to the shoulder of the round that would not chamber. After this, no more problems. Not saying that you are having the same problem, just saying that I had this once. And it will not cost to much to do a double check to see if this happened to you too. |
Another trick is to blacken a sized case with a Sharpie marker, then try to chamber it. That should show you where it's rubbing in the chamber. Are you crimping your case mouths into the bullet cannelure (if there) too? If not, try one and see if the cartridge chambers any easier. If it does, then it's likely your chamber is just a little shorter than avg. I have to trim my cases to 3.89 to get them to chamber easily without any crimping. If you have a Viper, my experience with them has been that they have tighter necks than usual and I have to turn the case necks to get a proper fit. |
| I do have a viper. I have turned some necks and that worked. I also had to really be concious of doing the quarter turn down from flush with the dies. I think I have it resolved. BTW do I have to resise them again after neck turning or can I load them up and shoot? |
They should be fine to load up after turning. I do like to have annealed them first. That seems to make for a better fire-formed case and minimizes any cracks/splitting that might occur on their first use. |

I use a Ken Light automated annealing machine as I do thousands of cases each month... Here's a simple rig that one of the FAR-50 shooters came up with: bohicaarms.com/forum/viewtopic.php?f=32&t=306 and a good article on the principles of annealing: www.6mmbr.com/annealing.html |
