I built a 458 SOCOM. Radical Firearms receiver, bolt and barrel. 5.5 oz buffer with a normal AR buffer spring.
I am reloading cast 500 grain bullets. (Lee Mold)
The bullets plunk well. The first shot loads and fires fine. The next shots are hit and miss. They fail to load into the chamber.
I changed the Mag to a C Products duramag for 458s and it helped, but the gun still fails to load the next round frequently.
What do I need to change?
Thank you in advance for your help!
